Dolostone – Geology is the Way
Dolostone, also known as dolomite (not to be confused with the mineral dolomite), is a type of carbonate sedimentary rock consisting predominantly of dolomite [CaMg(CO 3) 2] and to a lesser extent of other carbonates, like calcite and aragonite. Like the mineral, the name derives from the French mineralogist Déodat Gratet de Dolomieu, after whom also …

Dolomite – Geology is the Way
Dolomite [CaMg (CO 3) 2] is the second most abundant carbonate in carbonate rocks after calcite. Dolomite is named after Déodat Gratet de Dolomieu (1750 – 1801), a French geologist who first described this mineral and the carbonate rocks of the Dolomites, in Northern Italy, which are also named after him. Except for some relatively rare ...

Dolomite: occurrence, evolution and economically
Dolomite, the rock, contains a large proportion of dolomite the mineral. Ideal dolomite has a crystal lattice consisting of alternating layers of Ca and Mg, separated by layers of CO 3 and is typically represented by a stoichiometric chemical composition of CaMg(CO 3 ) 2 where calcium and magnesium are present in equal proportions (Fig. 1A) .

Dolomites and dolomitization | SpringerLink
Two types of dolomite formation are common, that is, dolomitization, which is the replacement of CaCO 3 by CaMg (CO 3) 2, and dolomite cementation, which is the precipitation of dolomite from aqueous solution in primary or secondary pore spaces. The term dolomitization is also, yet incorrectly, applied to dolomite cementation.

Dolomite Countertop Pros and Cons
Dolomite is a harder-than-average material and is not as fragile as marble. On the Mohs hardness scale, dolomite rates at 3.5 – 4, superior to marble's Mohs rating. A higher hardness rating makes it a durable and strong countertop over time, capable of supporting various uses while being resistant to wear and tear.
