Anatase
TiO2 Tetragonal, Trimorphic with Rutile & Brookite
If you want a fine specimen of Anatase in your collection you usually want one from the older localities in Switzerland or one from the newer ones from Norway. Which locality has produced better specimens? I prefer the ones from Switzerland, but also want a good one from Norway. There are many localities for Anatase and many localities produce beautiful sharp crystals that micromounters cherish. You could probably put together a collection of Anatase from over fifty localities if you tried. Most of the specimens would look rather nondescript and the Anatase crystals on them would be best appreciated under a microscope. Many micro sized crystals of Anatase are sharp, steeply bipyramidal and a translucent blue or brown in colour. Often they are growing on beautifully contrasting white quartz or Albite and make for striking specimens under the microscope.
Anatase is a commonly found in small quantities in alpine pockets where it can occur with its too other polymorphs. It is also found in many igneous and metamorphic rocks and as a fine-grained alteration product of various titanium bearing minerals. The number of localities that produce fine large crystals is quite limited but the number of localities that produce good micro crystals is much larger.

Austria
Carinthia, Hohe Tauern Mts, Ankogel group, Ankogel area
Area famous for orange to red Anatase crystals, especially Grauleiten mountain hasdelivered some outstanding red Anatase. Brown to almost black Anatase crystals come from the Plattenkogel mountain.
This area includes the mountains located in close vicinity to Ankogel mountain (3246 m), which is the second highest elevation in the Ankogel group and one of the highest elevations in the Eastern Alps. Specimens coming from this area are often simply labelled 'Ankogel'. However, the latter actually refers to Ankogel mountain only.

Anatase
Austria
Salzburg, Hohe Tauern Mts, Habach valley, Gamseck Mt. area, Leffler Brunnen
In 2005 a very interesting and prolific Anatase locality was discovered near the Leffler source in the lower Habach valley. Several Quartz fissures in black Phylite (Schwarzphylit, a grey to black Schist) were encountered holding hundreds of Anatase accompanied by Brookite, Rutile, Ilmenite, Apatite, Synchysite, Calcite, Aragonite, Adularia and Quartz crystals. Most of the Anatase crystals show a tabular habit and have an almost opaque black colour although blue Anatase crystals showing a double pyramidal habit have also been found in 2007. Two other noteworthy Anatase localities in the lower Habach valley close to the Leffler source are the Windbach and the Schönbach valleys, it is said that in the early 1900s or late 1800s an Anatase crystal has been found in the Schönbach area measuring 4 cm. Nowadays it is still quite easy to find nice blue Anatase in the Schönbach up to 0,5 cm in length. The best locality for Anatase in the upper Habach valley is the Teufelsmüle area, an area most famous for fantastic finds of electric green Sphene.

Austria
Salzburg, Hohe tauern Mts, Rauris valley, Grieswies
Many fine Anatase specimens have been found in the Rauris valley, especially from the Grieswies area, a shallow slope on the eastern side of Grieswies-Schwarzkopf mountain, adjoined by steep cliffs to the west. These rocks contain numerous clefts, some of which reach very large dimensions. The Grieswies itself is composed of rocksled material, dating back to prehistoric times when a large part of the northeast slope of Hocharn mountain slipped off.

Southeast Region, Minas Gerais
Minas Gerais, Minas Novas. In 1986 Ed Swoboda came to Tucson with “a superb lot of large, bluish black anatase crystals on matrix from Minas Novas…The largest crystal measures nearly 3 cm; most are 1 cm or so. The habit is typically bipyramidal; the matrix is smoky quartz. About 25 really good specimens and a couple of flats of mediocre material comprised the find.”1 Also, probably found at the same locality “sleek blue-black bipyramids to 2.5 cm long on brown quartz crystal matrixes; a 3.5 x 3.5-cm matrix with 2+ cm anatase crystals sold for $220.”2 The author was talking about some specimens at the Ste. Marie-aux-Mines mineral show in France in 1988. The locality Lavrinha means only little mine in Portuguese and is probably little more than a small pit.

Canada
Ontario, Wilberforce, Cardiff Mine
“Some of the titanite crystals from the Cardiff mine have been replaced by anatase resulting in light brown “leucoxene” pseudomorphs after titanite. Leucoxene is a discredited name, one that was given to a mixture of iron and titanium minerals.”1 George Robinson tells me via email that these pseudomorphs were found loose in the soil or in coarse calcite-syenite matrix. He says that he found crystals up to 7 cm, but the largest crystal was only a partial crystal and the most abundant associated minerals were allanite, pyroxene and microcline.

Mahaiza is a small town and a market place about 20 km west of the city Antsirabe and 10 km south of the city Betafo in the central highland of Madagascar. The town is easily accessible by car. Many minerals from numerous different localities, mostly south of Mahaiza -many as far away as 30-40km- are been brought here by local people for sale. Among the localities you'll f.ex. find the Tsaramanga (Itongafeno) pegmatite known for its beryl with the Tongafeno blue-colour and large good columbite xls. Or f.ex the Antsongombato gem mine, famous for its large londonite crystals. Minerals bought here in Mahaiza and which finds their way to foreign mineral collections are very often labeled just Mahaiza.
Anatase
Norway
Hordaland, Hardangervidda National Park
Hordaland Fylke, Ullensvang Statsallmenning, Matskorhae. This locality has also been know as Hardangervidda (vidda=high plateau). Local collectors informally call it “Grisebingen” which means the pig pen. The name is a derogatory Norwegian term for mineral pigs which would loosely be translated as “rockhound” and to the very dirty working conditions at the locality. Because of the deep snow the deposit can be worked only one or two months a year.1 The specimens show sharp blue-black steep bipyramidal anatase crystals, frequently doubly terminated, usually growing on well formed sharp transparent quartz crystals. Some of these anatase crystals are a deep blue if you hold them to a strong light. Most crystals are in the cm range, but fine crystals as large as 6 cm have been found, some of them on matrix. Many of the specimens from this locality are clusters of prismatic quartz crystals, lustrous and fairly transparent with cm size bipyramidal dark blue anatase crystals growing on them. On larger specimens the quartz crystals tend to be broken and the small anatase crystals tend to get lost against the overall aspect of the specimen. Two spectacular small matrix specimens from this locality with crystals of 2.5 and 6 cm each respectively are pictured in Rocks and Minerals Magazine, Nov/Dec 2002, p400-402. A good one of these will cost you over a thousand dollars and one of the best, perhaps $5000 or more.

Oppland, Valdres
Near Gudbransdalen, “Valdres region.” “At Siegbert Zecha’s stand were a few mostly thumbnail specimens of a remarkable new anatase from Norway, not to be confused with the older “Hardangervidda” or “Matskorhae” anatase – pointed blue-black bipyramids to 1 cm at most. These older ones, scattered on sometimes immense quartz crystal groups…. The new crystals feature, by contrast, flat basil terminations on the bipyramids; the matrix where present is drusy albite; and, though as dark-looking at first glance as the older crystals, these are not really blue but red, with richly glinting rubous highlights. Most often the crystals come as loose singles to 2.5 cm long, but sometimes they form parallel groupings which are extremely bright and handsome. The best matrix-free thumbnails of this sort cost around $200. Apparently the largest crystal yet found, now in the Kongsberg Mining Museum, is r.8 cm long… . The locality is (no surprise) very vague. “Valdres region” appears on some labels, and the big one (mentioned above) displayed by the Kongsberg museum at the recent Tucson show is labeled as coming from “near Gudbransdalen.[Mineralogical Record, Vol. 20, 1989, p 483]
Some of the specimens with Valdres labels are in fact from Dyrfonni. It should be noted though, that this locality has been staked out as a claim , and according to Norwegian mining laws it is considered as a theft to collect at this site without permission from the holder of the claim. Even so, at the end of the 1990s several people collected here illegally more than 200 pieces of anatase specimens and sold it to mineral shows in USA and Germany. Some collectors have thus been legally prosecuted. Specimens of anatase from this locality have been erroneously labelled as coming from "Valdres", probably to avoid prosecution or to keep the locality a secret.

Among the best localities in Tujetsch for Anatase are Val Nalps, Val Curnera, Cavradi gorge and Druntobel although probably the best Tujetsch Anatase locality remains the area around the Sontga Brigida chapel.

The area around the St Gotthard pass. In a geological sense, the St Gotthard massif encompasses the area from the Nufenen pass (Novena pass) in the west to the southern side valleys of the Tujetsch (Tavetsch) in the east. Hence, many of the localities in the upper Wallis, in northern Ticino (on the north slopes of the Bedretto valley and in the valleys northeast of the upper Leventina), and in western Grischun are actually situated in the St Gotthard massif. Though, this is not explicitly noted, except in some locality descriptions.
Anatase crystals in excess of 2 cm have been found in the St Gotthard massif.

Many Anatase crystals can be found on the slopes of Mount Basòdino near Lago del Zött, in the region around Pizzo del Arzo and the Cavagnoli glaciers in the upper Bavona Valley. Colours range from yellow, brown, red to black. The Anatase crystals are accompanied by Rutile (often as Sagenite), Brookite, Apatite, Titanite and Hematite (often as Eisenrose). They can be found in-situ as well as in landslide material.

Wallis (Valais), Binn Valley
Some collectors feel that the best anatase specimens come from the older and more classical Swiss localities like the ones from the Binntal. Here crystals can be found up to about 5 cm that are amber or brown in color. Several different crystal habits are found here. There is a matrix specimen in the Museum of Natural History in Geneva that has rough brownish black crystal on it that measures 1.8 x 4.5 cm. Another somewhat rough brown crystal on matrix in the Smithsonian Institute in the Carl Bosch collection from Alp Lercheltini, Binntal, measures 3.5x5.0 cm, another one measuring over 4 cm is in the Geneva museum. Most collectors would like their crystals to be sharper than these, but these are perhaps the reigning monsters, so far as Anatase is concerned. Lärcheltini is a zone high up in the Binntal that can be subdivided in several localities famous for good Anatas finds: Gorb, Riggi, Kollergraben and Spissen. The last one is known for the very typical "Spissen-habit" Anatase and in the lower Kollergraben very nice long prismatic yellow Anatase have been found in recent years. Other localities for Anatase in the Binn valley are: Tälligletscher, Balmen, Bochtenhorn, Ofenhorn, Mittlenberg, Turbenalp, Fäldbachtal, Blausee area, Cherbadung and Fleschsee. An interesting recent discovery from the Binn valley is the find of Niobian Anatase. To get a great one from the Binntal is like trying to leap a tall building in a single bound but the occasional superman succeeds. I don’t think I have ever seen a great one for sale. It would certainly cost you several thousand dollars. Here are some spellings for this famous locality that have been put on labels over the years. (Binntal also Binn, Binntales, Binnatal, Binnental, Binnenthal).

In 2005 a very interesting and prolific Anatase locality was discovered near the Leffler source in the lower Habach valley. Several Quartz fissures in black Phylite (Schwarzphylit, a grey to black Schist) were encountered holding hundreds of Anatase accompanied by Brookite, Rutile, Ilmenite, Apatite, Synchysite, Calcite, Aragonite, Adularia and Quartz crystals. Most of the Anatase crystals show a tabular habit and have an almost opaque black colour although blue Anatase crystals showing a double pyramidal habit have also been found in 2007. Two other noteworthy Anatase localities in the lower Habach valley close to the Leffler source are the Windbach and the Schönbach valleys, it is said that in the early 1900s or late 1800s an Anatase crystal has been found in the Schönbach area measuring 4 cm. Nowadays it is still quite easy to find nice blue Anatase in the Schönbach up to 0,5 cm in length. The best locality for Anatase in the upper Habach valley is the Teufelsmüle area, an area most famous for fantastic finds of electric green Sphene.

Minas Gerais, Minas Novas. In 1986 Ed Swoboda came to Tucson with “a superb lot of large, bluish black anatase crystals on matrix from Minas Novas…The largest crystal measures nearly 3 cm; most are 1 cm or so. The habit is typically bipyramidal; the matrix is smoky quartz. About 25 really good specimens and a couple of flats of mediocre material comprised the find.”1 Also, probably found at the same locality “sleek blue-black bipyramids to 2.5 cm long on brown quartz crystal matrixes; a 3.5 x 3.5-cm matrix with 2+ cm anatase crystals sold for $220.”2 The author was talking about some specimens at the Ste. Marie-aux-Mines mineral show in France in 1988. The locality Lavrinha means only little mine in Portuguese and is probably little more than a small pit.

Ontario, Wilberforce, Cardiff Mine
“Some of the titanite crystals from the Cardiff mine have been replaced by anatase resulting in light brown “leucoxene” pseudomorphs after titanite. Leucoxene is a discredited name, one that was given to a mixture of iron and titanium minerals.”1 George Robinson tells me via email that these pseudomorphs were found loose in the soil or in coarse calcite-syenite matrix. He says that he found crystals up to 7 cm, but the largest crystal was only a partial crystal and the most abundant associated minerals were allanite, pyroxene and microcline.

Mahaiza is a small town and a market place about 20 km west of the city Antsirabe and 10 km south of the city Betafo in the central highland of Madagascar. The town is easily accessible by car. Many minerals from numerous different localities, mostly south of Mahaiza -many as far away as 30-40km- are been brought here by local people for sale. Among the localities you'll f.ex. find the Tsaramanga (Itongafeno) pegmatite known for its beryl with the Tongafeno blue-colour and large good columbite xls. Or f.ex the Antsongombato gem mine, famous for its large londonite crystals. Minerals bought here in Mahaiza and which finds their way to foreign mineral collections are very often labeled just Mahaiza.

Hordaland Fylke, Ullensvang Statsallmenning, Matskorhae. This locality has also been know as Hardangervidda (vidda=high plateau). Local collectors informally call it “Grisebingen” which means the pig pen. The name is a derogatory Norwegian term for mineral pigs which would loosely be translated as “rockhound” and to the very dirty working conditions at the locality. Because of the deep snow the deposit can be worked only one or two months a year.1 The specimens show sharp blue-black steep bipyramidal anatase crystals, frequently doubly terminated, usually growing on well formed sharp transparent quartz crystals. Some of these anatase crystals are a deep blue if you hold them to a strong light. Most crystals are in the cm range, but fine crystals as large as 6 cm have been found, some of them on matrix. Many of the specimens from this locality are clusters of prismatic quartz crystals, lustrous and fairly transparent with cm size bipyramidal dark blue anatase crystals growing on them. On larger specimens the quartz crystals tend to be broken and the small anatase crystals tend to get lost against the overall aspect of the specimen. Two spectacular small matrix specimens from this locality with crystals of 2.5 and 6 cm each respectively are pictured in Rocks and Minerals Magazine, Nov/Dec 2002, p400-402. A good one of these will cost you over a thousand dollars and one of the best, perhaps $5000 or more.

Near Gudbransdalen, “Valdres region.” “At Siegbert Zecha’s stand were a few mostly thumbnail specimens of a remarkable new anatase from Norway, not to be confused with the older “Hardangervidda” or “Matskorhae” anatase – pointed blue-black bipyramids to 1 cm at most. These older ones, scattered on sometimes immense quartz crystal groups…. The new crystals feature, by contrast, flat basil terminations on the bipyramids; the matrix where present is drusy albite; and, though as dark-looking at first glance as the older crystals, these are not really blue but red, with richly glinting rubous highlights. Most often the crystals come as loose singles to 2.5 cm long, but sometimes they form parallel groupings which are extremely bright and handsome. The best matrix-free thumbnails of this sort cost around $200. Apparently the largest crystal yet found, now in the Kongsberg Mining Museum, is r.8 cm long… . The locality is (no surprise) very vague. “Valdres region” appears on some labels, and the big one (mentioned above) displayed by the Kongsberg museum at the recent Tucson show is labeled as coming from “near Gudbransdalen.[Mineralogical Record, Vol. 20, 1989, p 483]
Some of the specimens with Valdres labels are in fact from Dyrfonni. It should be noted though, that this locality has been staked out as a claim , and according to Norwegian mining laws it is considered as a theft to collect at this site without permission from the holder of the claim. Even so, at the end of the 1990s several people collected here illegally more than 200 pieces of anatase specimens and sold it to mineral shows in USA and Germany. Some collectors have thus been legally prosecuted. Specimens of anatase from this locality have been erroneously labelled as coming from "Valdres", probably to avoid prosecution or to keep the locality a secret.

Many fine Anatase specimens have been found in Tujetsch. One of the first written accounts about Anatase in Tujetsch can be found in Wiser (1841). he wrote about Anatase crystals up to 2,5 cm in length although normally the Anatase from Tujetsch don't exceed 0,5 cm. Among the best localities in Tujetsch for Anatase are Val Nalps, Val Curnera, Cavradi gorge and Druntobel although probably the best Tujetsch Anatase locality remains the area around the Sontga Brigida chapel.

The area around the St Gotthard pass. In a geological sense, the St Gotthard massif encompasses the area from the Nufenen pass (Novena pass) in the west to the southern side valleys of the Tujetsch (Tavetsch) in the east. Hence, many of the localities in the upper Wallis, in northern Ticino (on the north slopes of the Bedretto valley and in the valleys northeast of the upper Leventina), and in western Grischun are actually situated in the St Gotthard massif. Though, this is not explicitly noted, except in some locality descriptions.

Good localities for Anatase can be found in the two upper Maggia valleys; Bavona valley and Lavizzara valley.
Many Anatase crystals can be found on the slopes of Mount Basòdino near Lago del Zött, in the region around Pizzo del Arzo and the Cavagnoli glaciers in the upper Bavona Valley. Colours range from yellow, brown, red to black. The Anatase crystals are accompanied by Rutile (often as Sagenite), Brookite, Apatite, Titanite and Hematite (often as Eisenrose). They can be found in-situ as well as in landslide material.

Some collectors feel that the best anatase specimens come from the older and more classical Swiss localities like the ones from the Binntal. Here crystals can be found up to about 5 cm that are amber or brown in color. Several different crystal habits are found here. There is a matrix specimen in the Museum of Natural History in Geneva that has rough brownish black crystal on it that measures 1.8 x 4.5 cm. Another somewhat rough brown crystal on matrix in the Smithsonian Institute in the Carl Bosch collection from Alp Lercheltini, Binntal, measures 3.5x5.0 cm, another one measuring over 4 cm is in the Geneva museum. Most collectors would like their crystals to be sharper than these, but these are perhaps the reigning monsters, so far as Anatase is concerned. Lärcheltini is a zone high up in the Binntal that can be subdivided in several localities famous for good Anatas finds: Gorb, Riggi, Kollergraben and Spissen. The last one is known for the very typical "Spissen-habit" Anatase and in the lower Kollergraben very nice long prismatic yellow Anatase have been found in recent years. Other localities for Anatase in the Binn valley are: Tälligletscher, Balmen, Bochtenhorn, Ofenhorn, Mittlenberg, Turbenalp, Fäldbachtal, Blausee area, Cherbadung and Fleschsee. An interesting recent discovery from the Binn valley is the find of Niobian Anatase. To get a great one from the Binntal is like trying to leap a tall building in a single bound but the occasional superman succeeds. I don’t think I have ever seen a great one for sale. It would certainly cost you several thousand dollars. Here are some spellings for this famous locality that have been put on labels over the years. (Binntal also Binn, Binntales, Binnatal, Binnental, Binnenthal).

Brookite from this location was originally referred to as being from "near Snowdon" by Sowerby (1809), but this was later confirmed by Sowerby (1838) to be Prenteg. Also incorrectly called "Fonolen" by Greg and Lettsom (1858) and elsewhere described as "8 miles from Snowdon, between Beddgelert and Tremadoc".

Hi, Harjo -

I see above that you are looking for a sample of anatase replacing titanite - this piece is from the Bear Lake Diggings near Gooderham. Bill Plavic kindly gave us a piece for our thumbnail collection.
it certainly is the runt of the litter, looks-wise!

You probably also understand why collectors (including myself) do not post images of the best Anatase crystals on Mindat.
I'll come and have a look at them in Norway
