Abstract: The presenting of black shale series reflects abrupt environmental events,which formed many important ore-hosting rock series.There are high graphite bearing layers in most of the rock associations in Qingchengzi area of Liaoning Province.The high graphite-bearing rocks are regarded as black shale series.The Qingchengzi area,with several medium-large scale gold,silver,lead and zinc deposits ocurred in the ore-bearing rock series,is an important concentrated region for Au-Ag-multimetal mineralization.The forming of the deposits in the area is closely related to Paleoproterozoic volcanic eruptions.The ore-forming rock series should be turbidite origin.The large amount of CO2 released from subaquitic volcanic activities is favorable for the forming of black shale series.Biologic and metamorphic processes have played important roles for the mineralization.During the prospecting in Qinggchengzi area,we should also pay attention to other minerals occurred in the black shale series.
