Thanks for the advice. I've got several photo edit programs, and I often adjust the dynamic range of my photos.
In this case I'd rather leave the photo as it is, because it's much more true to the pitch black specimen. ;-)

I copied one of them into photoshop and lightened up the shadows a little. I don't know if the one you uploaded to mindat looks better of the one included here that I lightned up looks better. If this one looks better, you might consider lightening the shadows some in some of the other images and uploading them again. I think this is called called increasing the dynamic range of images. In a basic photoshope program it is very quick and easy to accomplish.

Unfortunately I don`t have a pic or a collectors name but I`m quite sure others have as its a well known specimen.

Then the large xtls (also excellent twins) on dolomite from Forchtenau [www.mindat.org] come in my mind.
I have huge specimen with way over 50kg weight in my cellar, but covered by 30 years of dust - so no good pic possible.

Then I remember the also huge xtls from Rohrbach near Ternitz (locality not present here on mindat yet) that I collected in my youth.

Can you help make this a better article? What good localities have we missed? Can you supply pictures of better specimens than those we show here? Can you give us more and better information about the specimens from these localities? Can you supply better geological or historical information on these localities?

Here will go a good picture of a calcite specimen from Austria and general remarks about the calcite from this country. Here are some url's to some of the better Austrian calcite specimens here on Mindat that can be considered for inclusion in the article. These, in most cases are just for temporary use until we can get images of the much better specimens that are almost certainly out there. We should also consider that there are probably localities out there with fine specimens that are not even mentioned on Mindat. Also in some instances there are sometimes pictures on Mindat, of specimens from a locality, but they were so ratty that I did not include them here, but there may also be really good specimens from there that we should talk about in this article.

Calcite from Bad Bleiberg FOV: 15 x 12,5cm © Rudo

As Calcite is found in most geologic settings it can be come across almost everywhere in Austria.
But there are currently only 127 Austrian localities listed in mindat due to the fact that in most
occurences the crystals are rather small and insignificant. Big and spectacular Calcite specimens have been
rescued in numerous alpine clefts, the Pb - Zn mines of the Bleiberg area, the iron - manganese mines
of Hüttenberg, the ancient silver mine of Oberzeiring, in several limestone outcrops like the "Krallaloch" at Götzis,
dolomite quarries like the Bundesstrombauamt quarry at Bad Deutsch- Altenburg.
To say where Austria's most aesthetic Calcites have been collected is a matter of personal taste. I have a preference
for those from the Pb-Zn mines of the Bleiberg district, the brilliant crystals found in some alpine clefts in the
Glocknerwand at Kals and the wonderful specimens from the huge cleft in Mitteldorferbachgraben at Virgen in East
Tyrol.

The ancient Pb-Zn mines of the Bleiberg area which had to be closed in 1993 because of falling prizes for lead and zinc produced over 50 different minerals with some of them in excellent quality. Best known minerals from there are: Wulfenite (Bleiberg is the type-locality), Hemimorphite, Cerussite, and Calcite in many different forms and habits. The most common form of the Calcite crystals measuring up to 16cm is the scalenohedral type that mainly was found in Antoni Mine and Max Mine.
Most attractive are the sometimes water clear prismatic crystals (Kanonenspat) from Stefanie Mine. But as there were not many excellent specimens rescued these brilliant crystals can only be seen in a few local collections.

In 1982 a huge cleft which contained more than 2 tons of Rock Crystals was opened on the south slope of Grauleitenspitze in the Ankogel group. Several teams worked the cleft which also produced nice Calcite twins in sizes up to 12cm and some one off specimens with Calcite crystals perched on Rock Crystals. As the cleft was right beside a path and so could be reached very easily each team working there only stayed as long as they were able to guard the cleft over night. As soon as they got tired and left the cleft the next team went in and rescued crystals as long as they could. For over three months this certainly was one of the busiest places in the Austrian Alps.

When the dams and the hydroelectric power plant were constructed during the 1950's, a number of manganese mineralizations were cut. The minerals usually appeared as finely grained inclusions in prasinites, free-standing crystals did not occur.
In summer 2007 collectors opened clefts with calcite and chlorite in the Mooserboden area.

Clefts in epidote-amphibolites of the so-called Knappenwandmulde series. The well known mineralization with outstanding epidote crystals is restricted to places where these clefts intersect with an aplite vein. The locality owes its discovery in 1865 to prospection works in search of copper ores, which occur at several places both at the Knappenwand and in its vicinity. Rarely, fine bornite crystals occur in association with epidote. The deposit was intermittently worked for epidote until 1956. Later, specimens were recovered during a scientific project guided by staff from the National History Museum of Vienna.
Presently (2007), the site is leased by the Zukunftkollegium Neukirchen and mined for specimens.

Famous Fluorite locality which also produced Calcite crystals.
The area around Weißeck mountain is dominated by dolomites and limestones of the Radstadt formation. They occupy an area that is elliptical in plan view, about 3.5 km long and up to 1.5 km wide, with Weißeck mountain located a little south of its center. Fluorite is found in outcrops and loose boulders in numerous places on the slopes, either in clefts or in quartz veins. These occurrences have been known since the late 18th century.
Located on the ridge between the Murwinkel and the upper Zederhaus valley.

Currently (2009) a tunnel is driven (at an inclination of about 28°) up the mountain to gain underground access to two large diabase lenses higher up on the mountain. These lenses, and additionally metasandstones and metagreywackes, will be exploited in a large open-pit quarrying operation and the rock material will be transported through the tunnel down to the processing plant.
The quarry will be closed and backfilled starting sometime in 2010.

Located NW of Bruck an der Mur. Well known mineral locality because of its excellent Strontianite crystals.

Comprises the districts/mines Angerer, Kaintaleck and Wiesergut (Wieser) (all separate (sub-)localities).
Located in 1852, magnesite mining started in 1870, in 1906 the industrial production of magnesite products started. In 1911 the first furnace was built in Oberdorf. Now the Styromag Company operates one surface mine (Kaintalegg at N47.44602 E15.09434) and two underground mines (Angerer at N47.45696 E15.11423 und Wiesergut at N47.45778 E15.11683).
The furnaces are still in Oberdorf (parish St. Katharein an der Laming).
From 1945 – 1963 the Wiesergut-mine was also used for the production of talc.

Despite its great size, Canada doesn't have any outstanding and prolific calcite localities. Nonetheless, there are many localities that produce very nice calcite specimens and the occassional excellent specimen. The photos below highlight some of the better known localities or those that might be lesser known but have still produced nice specimen for which photos are available.

Shoreline exposures. The calcite forms in vertical fault veins and less often in isolated pods. These occur in Triassic sandstone and to a lesser degree in the overlying conglomerate. Some of the crystals reach a large size (approx 10cm+) but these are usually contacted, due to the limited space available for growth.

Nova Scotia, Hants County, Walton




There are several small manganese deposits in the area around Walton. These occur in a brown shale. Generally the crystals are dogtooth scalenohedrons, brown to creamy white in color. Very steep and pointed crystals, and blocky rhombohedrons have also been found.

More attractive specimens are black due to heavy inclusions of manganese oxides. In some cases the manganese oxides (identified as groutite) have replaced the calcite in excellent pseudomorphs. Calcite twins have also been found. In addition to the Mn-oxides, the calcite is also associated with barite.

Crystals in vuggy limestone exposed on the shore of Lake Huron. The mineralized layer is often below high water level. The crystals are very complex with many faces, both flat and rounded, and also hoppered faces. Many of the crystals are twinned along the c-axis. Though they don't get large, they are very interesting to the calcite collector. At this locality, the lustrous calcite crystals are usually found in clay-filled seams while the more frosted crystals are not formed in clay. Associated minerals include sprays of strontianite and blue celestine. The locality is now inside a provincial park.

This was preceded by Steetly Industries (1951 - ?) which operated two pits fronting on Hwy 5, which was in turn was preceded by Canada Crushed Stone (1912 - 1951).
All quarries and their names reflect a continuous operation with the name changes tracking the historical progression of ownership and the several pits which were consecutively and concurrently worked.

Formerly: Mathers quarry, Saint-Eustache, Deux-Montagnes Co., Québec, Canada. Recently (2011) renamed "Carrière et pavage Saint-Eustache". This active five-level quarry has been in operation since 1961. As of 2012, it spans some 850 m in length, a width of 350 to 750 m, and a depth of roughly 50 m.

The following description is taken from the Deposit File of the MRNF (Ministère des ressources naturelles et de la faune) : The main rock type is a very fine-grained, pale medium grey siliceous dolostone, in generally thick beds and marked at places with fine clay laminae. This rock is irregularly interstratified with a dark grey, fine grained dolostone, in thin beds separated by thin interbeds of shale, and by thick beds of fine grained, medium dark grey dolostone dotted with small cavities filled with white crystalline dolomite. These strata are assigned to the Beauharnois Formation of the Beekmantown Group.
