Economic Geology

ECONOMIC GEOLOGY CONCEPT Economic geology is the study of fuels, metals, and other materials from the earth that are of interest to industry or the economy in general. It is concerned with the distribution of resources, the costs and benefits of their recovery, and the value and availability of existing materials.

Indian Rock System: Archaean, Purana, Dravidian Aryan

Jan 17, 2016Gneiss == Mineral composition varies from granite to gabbro. Schists == mostly crystalline, include mica, talc, hornblende, chlorite, etc. These rocks are: Oldest rocks [pre-Cambrian era] [formed about 4 billion years ago]. Rocks formed due to solidification of molten magma – the earth's surface was very hot then. Get price

Economic geology

Economic geology deals with the formation, discovery, and extraction of mineral resources. These include construction materials (sand, gravel, building stone and limestone for cement) and nonmetallic resources (feldspar, mica, clay, potash, phosphates, fluorite, barite, diamonds, gem minerals, abrasives and many others).

mica

Mica, any of a group of hydrous potassium, aluminum silicate minerals. It is a type of phyllosilicate, exhibiting a two-dimensional sheet or layer structure.

Non-Metallic Mineral Distribution in India – Mica, Limestone, Dolomite, Asbestos, Magnesite, Kyanite, Sillimanite and Gypsum. Mica Mica is a naturally occurring non-metallic mineral that is based on a collection of silicates. Mica is a very good insulator that has a wide range of applications in electrical and electronics industry. It can withstand high voltage and has low power loss factor. Get price

Uses of mica

Uses of mica mineral: Mica is non-toxic mineral. It is one of the important ingredient in makeup and various cosmetics. It gives a shimmery effect and adds sparkle. It gives a glowing effect with a natural finish. There are no side effects and suits for all types of skin. To avoid mica in skin care products you can check the product label. Get price
