What Is the Composition of a Lava Rock? Sciencing

Apr 24, 2017The composition of a lava rock is a function of its mineral structure and chemical arrangement. One factor determining an igneous rock's composition is its classification as either a felsic or mafic rock. Felsic rocks are dominated by silicon and aluminum minerals, whereas mafic rocks are dominated by magnesium and iron minerals.

The composition of limestone What is limestone

Dolomite. It is a carbonate mineral that often forms from calcite. Sometimes liquids rich in magnesium carbonate (MgCO 3) (an atom of magnesium, an atom of carbon and three atoms of oxygen) pass through a limestone. When this happens, the CaCO 3 of the calcite picks up the MgCO 3,
