Mineral Specimen Coal

Features: OOLITIC LIMESTONE | Oolitic limestone is a carbonate rock formed from the cementation of thousands of ooids. Ooids are tiny nodules formed from the accumulation of carbonate material around...

Features: CHERT | Sometimes referred to as flint, Chert is a sedimentary rock rich in silicaGREAT FOR GEOLOGY CLASSROOMS | This specimen is perfect for teaching geology students about the many forms...

Features: DOLOMITE | Though similar to calcite, the inclusion of magnesium in the chemistry of Dolomite makes it a more robust & stable mineralGREAT FOR GEOLOGY CLASSROOMS | Ideal for learning about...

Features: GALENA | Galena grows in beautiful metallic cubes. Often refined as lead ore, galena can also be used to teach students about a mineral's luster, streak, and cleavage. Because of the lead...

Features: GRAY LIMESTONE | The massive, gray variety of limestone is often found deposited in marine environments. It is made up of organic material, primarily calcium carbonateGREAT FOR GEOLOGY...

Features: LIMESTONE CHALK | Limestone is made up of organic material, primarily calcium carbonate. The chalk variety consists of the shells of coccolithophores, small platy animals that stack...

Features: LODESTONE | This naturally magnetized mineral creates it's own magnetic field and can pick up small metal objects. Iron particles cover its surface. As an iron oxide, lodestone has a...

Features: MUSCOVITE MICA | Muscovite mica is a mineral that forms from cooling magma. It forms in thin sheets that are individually weak, but comprehensively strong. Mica is a major component in a...

Features: OLIVINE | Much of the earth's surface is covered in oceanic crust, of which olivine is a major component. With the highest crystallization temperature, olivine is the first mineral to form...
