| Abstract: | Volcanogenic deposits produced at specific stages of volcanism. They coincide with volcanic structures in time, space and genesis. The evolution of volcanic mechanism are divided into four stages related to different mineralizations and different deposits, respectively. The non-metal deposit of acidic rock series formed in major eruption stage; The high-mesothemal deposit and secondary quartzitc non-metal deposit formed in caldera-instrusion (extrusion) stage; The epithermal deposit formed in hydrothermal circulation stage post-volcanism.
The major metal and non-metal deposits in this area related to volcanic mechanics occure in: ring fractures and radial rifts; ring fracture around volcanic mechanics; contact zones of intrusive (extrusive) rocks, cryptovolcanic rocks; composit parts of volcanic structures and regional faults and sliding fracture zones between beds. The volcanic-mineralization compounding model are set up according to the data mentioned above. |
