Fossiliferous dolostone

The red variety of chert is called jasper. Dark gray to black chert is called flint. • The carbon-rich rock formed from ancient plant material is called coal. Sedimentary rocks with non-clastic texture include fossiliferous limestone (above left), chert (above right) and coal (right). All three of these rock types can be found in Virginia..

Dolostone, also known as dolomite (not to be confused with the mineral dolomite), is a type of carbonate sedimentary rock consisting predominantly of dolomite [CaMg(CO 3) 2] and to a lesser extent of other carbonates, like calcite and aragonite. Like the mineral, the name derives from the French mineralogist Déodat Gratet de Dolomieu, after whom also the Dolomites of Italy, where the rock was ...Dolostone, also known as dolomite (not to be confused with the mineral dolomite), is a type of carbonate sedimentary rock consisting predominantly of dolomite [CaMg(CO 3) 2] and to a lesser extent of other carbonates, like calcite and aragonite.
