Galena type of rock
Galena – Brushy Creek Mine, Oates, Viburnum Trend District, Reynolds County, Missouri - 15 x 12 x 8.5 cm. - Iridescent octahedral galena crystals dominate this specimen that also has sphalerite, dolomite and chalcopyrite in association. The iridescence is caused by a microscopic layer of chalcopyrite on the galena. Sedimentary, metamorphic and igneous rocks are found in Georgia. The state has four distinct geographic regions, and different types of each rock can be found throughout the land. The northwest corner of Georgia falls into the Valley and Ri...

Photos and information about 80 common rock-forming, ore and gemstone minerals from around the world.Minerals form when atoms bond together in a crystalline arrangement. Three main ways this occurs in nature are: 1) precipitation directly from an aqueous (water) solution with a temperature change, 2) crystallization from a magma with a temperature change, and 3) biological precipitation by the action of organisms.
