Abstract:The geotectonic setting, the geology of ore deposits, geochemical and sedex rock characters and metallogenetic temperature were studied, as well as metallization phase and stages of mineralization of Laochang ore deposits. It was considered that the Laochang ore deposits should be contained in the submarine volcanic sedex-reformed deposits in Lancang rift. The "three-storey building pattern" metallogenetic model was established, which has important theoretical and guiding significances for the prospecting in future.
Key words: massive sulfide deposits genesis of deposit metallogenetic model
