PPT-Optical Properties of Minerals

UNIT 4 They assist in the identification of minerals study their optical properties under the microscope Minerals are inorganic chemical compounds having a certain lattice shape size and symmetry being a result of the geometrical arrangement of the constituents chemical elements such as Si Al O . Geologists use characteristics to tell one mineral from another. What is a Mineral?. Must be a solid.. Must occur in nature.. Must have a definable chemical composition (. NaCl. ).. Must have a crystalline structure.. Magnetism Feel. Taste . Smell. Optical Properties. Magnetism. Lodestone – natural compass. Magnetite. Feel. Graphite. feels greasy. Talc. feels soapy. Taste. Halite. is rock salt, so it tastes salty.. biotissues. D.A. Loginova. 1,2. , E.A. Sergeeva. 1. , P.D. Agrba. 2. , . and M. Yu. Kirillin. 1. 1 .

A pure substance, such as a mineral, can be identified from observations and tests performed to determine its physical properties. These properties are based on the unique structure of the substance..
