Granite: Igneous Rock, What is Granite? Granite is a light-colored igneous rock with grains large enough to be visible with the unaided eye It forms from the slow crystallization of magma below Earth's surface Granite is composed mainly of quartz and feldspar with minor amounts of mica, amphiboles, and other mineralsThis mineral composition usually gives granite a red, pink, gray, or white color with dark mineral ,Locations of Deposits, Almost all phosphorus is mined as phosphate rock (PO4) Deposits are typically found in shales, cherts, limestone, dolomites and sandstone as well as hydrothermal veins or as chemically dissolved phosphate minerals in igneous and metamorphic rocks One of the world's largest phosphate deposit is the Phosphoria Formation, located in southeast IdahoGranite, Granite (/ ˈ ɡ r æ n ɪ t /) is a coarse-grained igneous rock composed mostly of quartz, alkali feldspar, and plagioclaseIt forms from magma with a high content of silica and alkali metal oxides that slowly solidifies undergroundIt is common in the Earth's continental crust, where it is found in various kinds of igneous intrusionsThese range in size from dikes only a few inches across to ,Exploration Potential, Mining companies in Zambia focus on excerpting copper and uranium, as well as gold, nickel and industrial deposits, which are more limited For companies interested in mining operations, or the opening of mining companies, in Zambia, the Zambian Ministry of Mines, under which the Chamber of Mines is located, is the first port of callMineralization types in the Mozambique Belt of eastern Zambia, Oct 01, 1994· Main host rocks and mineralization types in the Mozambique Belt of Eastern Zambia Host rock Sands and Gravels Quartz veins Pegmatite Gabbro Schists and metavolcanics Paragneisses and granulites Disseminated graphite of metamorphic origin Paragneisses and Volcanogenic massive Zn-Cu sulphide amphibolites deposits Mineralization type Deposit ,.
