Read MoreMinerals are naturally occurring, homogeneous inorganic solid substances having a definite chemical composition and characteristic crystalline structure, color and hardness. For example, copper pyrite (CuFeS 2), calamine (ZnCO 3) etc. are minerals. A mineral from which metal can be economically extracted in a maximum amount is called an ore.
Read MoreColor: Most minerals have a distinct color while others are variable in color. Hardness: A measure of a mineral's resistance to scratching. This is measured by scratching it against another substance of known hardness on the Mohs Hardness Scale.

Read MoreGeologists recognize two categories of weathering processes . Physical Weathering - disintegration of rocks and minerals by a physical or mechanical process.; Chemical Weathering - chemical alteration or decomposition of rocks and minerals.; Although we separate these processes, both work together to break down rocks and minerals to smaller fragments or to minerals more stable near the Earth's ...
Read MoreIn geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.. The geological definition of mineral normally excludes compounds that occur only in living beings. However some minerals are often biogenic (such as calcite) or are organic ...
