Limestone vs Dolomite: What Are They, And What''s The …

Dolomite is a type of limestone that contains magnesium crystals. The Dolomite is slightly more complex than limestone. Limestone has a hardness of 3, while Dolomite has a hardness of 3.5 to 4. Dolomite smolders more slowly than calcite. Dolomite effervesces gradually with dilute hydrochloric acid, whereas calcite fizzes vigorously.

sedimentary rock

Limestones and dolomites. Limestones and dolomites are collectively referred to as carbonates because they consist predominantly of the carbonate minerals calcite (CaCO 3) and dolomite (CaMg[CO 3] 2).Almost all dolomites are believed to be produced by recrystallization of preexisting limestones, although the exact details of this dolomitization process continue to be …

Alkalinity and Hardness

Alkalinity and water hardness are fairly similar--essentially they both come from sources in nature. Water moves through rocks (and picks up minerals as it does so) on its way to rivers and lakes.

In rocks, it is a function of the densities of the individual grains ...

What is the hardness of shale on the Mohs scale of hardness?

 · Shale does not have a Mohs hardness listing as it''s a rock, not a mineral. What is the hardness of dolomite on the MOHS hardness scale? Dolomite has a hardness of 3.5-4 on the Mohs scale of hardness.

Difference Between Limestone and Dolomite

 · Dolomite. Dolomite is also a carbonate mineral but is made of ''calcium magnesium carbonate'' instead of pure calcium carbonate material. Therefore, dolomite is called a double carbonate rock, and it doesn''t readily dissolve in dilute acidic media. The way dolomite is formed is not quite clear, and it has been found that it forms under high ...
