Processes of hydrothermal-sedimentary and hydrothermal ore formation are developed inside the ore-magmatic systems which include the deep (relatively deposits) intrusive bodies and hydrothermal fluid flows associated with these bodies. Ore matter in such systems could be extracted by the fluid from the host rocks and magmatic melts. The primary sedimentary and redeposited ores could be formed in ore-magmatic systems and redeposition is caused by temperature gradients there. During evolution of ore-magmatic system the primary sedimentary ores could be transformed into hydrothermal metamorphoused and redeposited ones.
