Those are really nice. Have you uploaded them to Mindat's image gallery. They deserve to be in the best mineral article for Canadian, Calcites. Would you like to writ it?

As I said, I don't have measurements for the first two and I need a better pic of the last one.

I could work on an article. But you'll have to promise to come to the east coast for a visit and have some lobster!

I'll need to find out more on how to write the article, what format you are looking for, what types of info to include, how to add inline pics, etc. Could you point me to this info?

OK, I understand. You can write the article in Word or notepad or any other word processor and then transplant it here into these fields. However I would advise you to write it right here in one of these fields just like the one you answered my post telling me I had to eat lobster on the east coast or the one where you will respond to this post. I work in these fields all the time and all of the best minerals articles are created in them by importing the selected images, arranging them to look nice and then writing the text associated with each set of pictures. Its sort of like one of those pizza places where you look in the window and see the guys making the pizza and making you drool and want to go in and help and get some of the pizza. It encourages others to jump in and help, and by the time you finish the article, or at least the first draft, you will come to know how little you know and how much others can help you if you can talk them into helping. Some of the suggestions will be just silly, but many of them them will be very helpful and will offer good suggestions for making the article better.

I have found that just the process of selecting the images and bringing them into these fields will start you thinking about what you want to say about them. At the beginning of the Best Minerals section there is a post that will explain how to go about doing it all and the general format that we all agree to follow. There are not hard and fast rules, and we are still tinkerning with them and experimenting to make them better. You can also look at other articles that have already been made to see what the suggested format looks like. Here is a list of the articles where the first draft has been complete.

Take a look at your post above, the one I am answering in this field. I have imported an image. You can click on the edit button and look at the code string that I used to import the image and you can fiddle with the numbers in the code string to change the picture to another or make it larger or smaller or to center it left, right or center and where to enter the caption for the image.

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?

Marcasite in calcite, 4.5 cm

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.

CalciteCanadaBritish Columbia, Slocan Mining Division, Riondel, Blue Bell Mine

Calcite, 9.3 cm

CalciteCanadaNew Brunswick, Gloucester Co., Bathurst Parish, Bathurst Mining Camp, Brunswick No. 12 mine (Brunswick Mining & Smelting Corp. No. 12 mine)

A lead-zinc mine located 26 km SW of Bathurst. The world's largest underground zinc mine and its fourth largest zinc producer. Owned by Brunswick Mining & Smelting Corp. Mine went to at least the 2,350 level. In the 1990s a dealer brought a small number of calcite specimens to collectors in Nova Scotia. They were very white in color and lustrous. They had a small rounded crystals surrounded by a wide flat disc (picture Saturn).

In basalt with zeolites.

CalciteCanadaNova Scotia, Hants County, Tenecape (Tennycape)

Calcite, 3.5 cm
Calcite twin, 3.8 cm

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.

CalciteCanadaNova 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.

CalciteCanadaOntario, Bruce Co., Bruce Township, Inverhuron

Calcite, 8.5 cm
Twinned calcite, xtl 26 mm
Calcite, 8 mm FOV
Calcite and strontianite, 8 mm FOV

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.

CalciteCanadaOntario, Peel Region, Belfountain, Forks of the Credit

Calcite, 7 cm

In exposures near contact of Silurian dolomitic limestone and underlying Whirlpool sandstone along the valley of the Credit River and quarries in the vicinity. There are 5 quarries that were notable for operation in the area surrounding Forks of the Credit: Big Hill Quarry, Cox Quarry, Hillis Quarry, Crowsnest Quarry, and Yorke Quarry. Most of these quarries have been long abandoned in the 1920's and are now overgrown.

CalciteCanadaOntario, Rainy River District, Hutchinson Township, Atikokan

Calcite, 9 cm

Dundas Quarry; Redland Quarry; Lafarge Quarry; Steetly Quarry; Steetley Quarry; Canada Crushed Stone Quarry

In 2008, there were three pits in existence. One active and two being used for storage and processing. There have been several owners of the pits, the most recent being LaFarge Ltd. 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.

CalciteCanadaQuébec, Laurentides, Deux-Montagnes RCM, Saint-Eustache, Carrière et pavage Saint-Eustache (Saint-Eustache quarry; Mathers quarry)

Calcite, 7 cm
Calcite, 3 cm

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.

Formerly: Marcil quarry, Sainte-Clotilde-de-Chateauguay, Chateauguay Co., Québec, Canada. Operated since 1998 by Les Pavage Chenail Inc.

Operating (1980-2008) quarry in dolomitic limestone (Beekmantown formation). Superb calcite and quartz specimens were found in large cavities in the 1990s. The quarry is also known for pyrite, chalcopyrite, anatase, sphalerite, barite and some secondary copper minerals.

The about 25 quarries in the area ca. 50 km from this quarry are all in different geological formations and all of the dozen of quarries closest to Sainte-Clotilde are in Chazy shale, Potsdam sandstone and other formations.

A wide variety of calcite forms are present from this locality.

Calcite and pyrite, 3 cm FOV
Calcite, 4.5 cm

Formerly: Niobec mine, Saguenay (Chicoutimi), Le Fjord-du-Saguenay Co., Québec, Canada

In operation for more than 25 years. Located 15 kilometres northwest of Saguenay city (merged in 2002 with Chicoutimi city). Notable for large, thick prismatic barite crystals.

The Niobec orebody, which measures 600 metres by 800 metres, is situated in the southern part of the Saint-Honore carbonatite complex, which is mainly comprised of dolomitic carbonates in the centre and calcitic carbonates on the edges. This carbonatite is an oval-shaped pluton covering 12 square kilometres. The Niobec property now covers a total area of approximately 1,735 hectares, comprising two mining leases and also includes 43 claims totaling 1,605 hectares.
