sedimentary rocks dolomite
Dolomite (also known as dolostone, dolomite rock or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO 3 ) 2. An example of this test is done when distinguishing calcite from dolomite, especially within the rocks (limestone and dolomite respectively).
dolomite_
dolomite /ˈdɒləˌmaɪt/. 1.N a white mineral often tinted by impurities, found in sedimentary rocks and veins. It is used in the manufacture of cement and as a building stone (marble). Composition: calcium magnesium carbonate. Formula: CaMg (CO3)2.
List of Important Sedimentary Rocks | Geology

Also, it may occur at the extended boundaries of many limestone deposits. These indicate locations where magnesium rich ground waters could have an easy access for the ...

Dolomite Rock Quarry. Deming New Mexico. 575-544-1867. About Dolomite. Dolomite is a sedimentary rock composed primarily of the mineral dolomite. Dolomite is very similar to limestone as they share the same colors and are formed in much the some ways. But dolomite is slightly harder than limestone and is slightly less soluble in dilute ...
Dolomitic sedimentary rocks
· Dolomitic sedimentary rocks. L imestone and dolomite are often found together, or closely associated, but their relationships are not always clear.
