WebA fossil is the preserved remains or traces of a dead organism. The process by which a fossil is formed is called fossilisation. It’s very rare for living things to become fossilised. WebDolostone is composed of the mineral dolomite, (Ca, Mg)CO3, whereas limestone is generally composed of calcite, CaCO3. Dolostone contains more magnesium (a trace impurity in natural calcite) and has a different crystalline structure. Dolomite can form through chemical alteration of limestone by reaction with groundwater bearing magnesium. irs corp estimated payments
