Limestone

2020-10-13 · Basically, commercial limestone is much richer in calcite and dolomite and poorer in other rock materials than most of the limestone as defined by the academic community. Because of its higher purity, commercial-grade limestone is generally stronger, holds up better as a building material, and is less susceptible to being degraded by weathering.

What is Dolomitic Limestone? (with pictures)

Dolomitic limestone is a type of rock that includes up to 50% dolomite. Normal limestone is primarily made up of calcite and aragonite, but dolomite forms in the stone when the calcium ions in the calcite part are replaced by magnesium ions — this process is called dolomitization.
