Magmatic Segregation - The igneous process that generate some of these metal deposits are quite straightforward. It is important in the late stages of the magmatic process. Water and other volatile substances do not crystallize along with the bulk of the magma body, these fluids make up a high percentage of the melt during the final phase of solidification. Pegmatites - Crystallization in a fluid rich environment, where ion migration is enhanced, results in the formation of crystals several centimeters. Diamonds igneous origin. they originate 200 km where the confining pressure is hight enough to generate carbon. Hydrothermal solutions - Hot water the best known and the most important ore deposits are those generated from hydrothermal solution. Disseminated deposit - ores are distributed as minute masses throughout the entire rock mass. thats how most of the copper is extracted by disseminated deposits.
