An ironstone (76) is a sedimentary rock that contains more than 15% iron, which may be present as variable proportions of iron-bearing minerals such as goethite, siderite, and berthierine. Sedimentary ironstones may be hard and calcareous and contain quartz grains, ooliths, pebbles, and a wide variety of macrofossils.

Read MoreHypersthene: Hypersthene is an important iron-rich orthopyroxene in the Pyroxene group with an orthorhombic crystal system.Other orthopyroxenes forming a complete chemical series with hypersthene are enstatite and bronzite. When the iron content of enstatite increases than it is converted into hypersthene, therefore it is opaque.
