Composition: dolomite and fossils Metamorphoses to marble Environment: Sea water, high in magnesium, flows through porous limestone and replaces some of the calcium with magnesium turning limestone into dolostone. Fossils are plants or animals that have been preserved in rock as organic carbon, chitin, or some mineral that replaced the original ...
Claystone vs. Limestone: Composition: Claystone is composed of clay-sized particles, while limestone is predominantly made up of calcium carbonate (calcite or aragonite). Limestone often contains fossils and has a higher mineral diversity. Hardness: Limestone is generally harder than claystone due to the presence of minerals like …
