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. This type of rock was once referred to as magnesian limestone ...
