Analysis on Metallogenetic Conditions of Bainiuchang Ag Polymetallic Ore Deposit in Mengzi County of Yunnan Province

Mengzi county,Bainiuchang deposit is located in the southwest margin of south China fold system.By analyzing this deposit of the regional geology and ore deposit geological feature,it is decided that this ore deposit belongs to deposit-reform-magmatic hydrothermal superimposed deposit.The formation of this deposit is mainly affected by the strata and magmatic rock controlled,the lower Cambrian rock mining area of existing in metallogenic element of the original syngenetic enrichment,for the formation of the deposit to provide some material source.At the same time,Bozhushan granitic magma intrusion action for the formation of the deposit provides the heat source of ore-forming fluid and metallogenic element.
