Dolomite pseudomorph after halite from Oklahoma, USA.

A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are over 6100 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.

The carbonate minerals all contain one or more carbonate (CO3-2) anions.

Dolomite is a calcium magnesium carbonate - CaMg(CO3)2. Many ancient rock units (dolostones) were long known to be composed of dolomite. Strangely, dolomite couldn't be found forming in modern oceans. Modern seas do precipitate aragonite, a calcium carbonate mineral. Cores drilled on coral atolls show that dolomite occurs at depth, below beds composed of calcite (= hexagonal CaCO3), which in turn occur at depth below beds composed of aragonite (= orthorhombic CaCO3). Dolomite appears to form principally by the addition of Mg to pre-existing limestones (rocks composed of CaCO3). Dolomite is also now known to precipitate directly from water in a few localities (e.g., some oceanic tidal flats and some lakes).

Dolomite has a hardness of about 3.5 to 4 on the Mohs Hardness Scale. It tends to form pinkish or whitish curved rhombic crystals ("saddle dolomite"). Dolomite will bubble (effervesce) in acid if powdered first. The bubbles are carbon dioxide gas. If the acid is dilute hydrochloric acid, the chemical reaction is:

4HCl(aq) + CaMg(CO3)2(s) -->> 2CO2(g)↑ + 2H2O(l) + Ca+2(aq) + Mg+2(aq) + 4Cl-(aq)

A pseudomorph is a mineral that has replaced another mineral, but still retains the original crystal shape. Seen here is a halite crystal (NaCl - sodium chloride) that has been completely replaced by dolomite.

Magnesite is a magnesium carbonate mineral (MgCO3). It is the end member of a chemical continuum with dolomite (CaMg(CO3)2) and calcite (CaCO3). It often forms coarsely-crystalline masses or chalky / earthy masses. It has a nonmetallic luster and can be any color, but is often whitish. It has a white streak, a hardness of about 3.5 to 4.5, and rhombohedral cleavage. Magnesite is usually the result of metamorphic chemical alteration of Mg-bearing rocks such as peridotites and serpentinites by the action of carbonic acid-rich fluids.

Seen here is a magnesium ore sample - this is rock-forming, very fine-grained magnesite from a mine in west-central Nevada. At the site, magnesite and brucite (Mg(OH)2) are mined for their magnesium content. The deposits are hosted by the Triassic-aged Luning Formation. Published research indicates that dolostones in the upper Luning Formation were hydrothermally altered to magnesite. Brucite in this area formed subsequently by contact metamorphism (metasomatism) of the magnesite during emplacement of a granodiorite intrusion in the Jurassic or Cretaceous.

Or so the sign would have you believe, a miracle mineral. Well, I do use some for cramps in my legs and it seems to help. At the Eumundi Market, one of, if not the largest market in South East Queensland inland from Noosa. It operates on Saturday and Wednesday and the day we went a month ago before my back decided to give up, it was mid week and crowded. Just at the end of the school holidays so that explains the crowds.

The markets are built along the old Bruce Highway and the old Eumundi Railway station in town and have been operating since 1979 when the station was superseded by an alternative route to reduce grades through the Blackall Ranges. So there are some fine establishments in town as well. Don't think the Gold Coast has it all!
