| Abstract: | The silver bearing source unit of the Laochang lateritic silver deposit is carbonate rock of middle and upper Carboniferous. This paper deals with the metallogenic conditions of the deposit. It is suggested that the formation of the silver bearing source unit has a great deal to do with continental marginal rift structure and sedimentary exhalation of middle and late Carboniferous and has some indirect relations with early Carboniferous volcanicity. The conditions of silver secondary enrichment are warm and humid paleo climate, relatively gentle paleo topography, lithololgy of carbonate rock and stratigraphic horizon of middle and upper Carboniferous. The prospecting criteria for Laochang type lateritic silver deposit was put forward in the end. |
