Current theories of the genesis of ore deposit can be divided into,Learning Geology: Ore forming processes,17-09-2014· Hydrothermal process Hydrothermal process is the most common ore forming process. Water is heated by the magma chamber and this water dissolves metals. Metals are dissolved in the water and this solution seeps through cracks, fractures and through permeable rocks until they are precipitated and form a deposit.Ore forming processes - Aalto,Examples of igneous/magmatic ore formations • Chromite and Fe-V-ores – Nearly monomineralic layers in layered mafic intrusions – fractional crystallization + gravitational settling do not explain the formation • Mixing and mingling of magma pulses: Irvine model • Changes in oxygen fugasity • Pressure changesOre forming process - SlideShare,17-09-2017· Ore forming process 1.
