Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater. Question: UESTION 5 10 points Save Answer Identify the unknown samples. *Remember* clastic rocks are composed of fragments, or clasts, of pre-existing minerals and rock. Chemical rocks are rocks that form by precipitation of minerals from water and contain only one mineral Biological rocks are rocks that form when living organisms die, pile up, and are then compressed
