Geological Characteristics and Prospecting Direction of Taishanmiao Copper Deposits in Fengxian County,Shaanxi Province
摘要
Abstract
The Taishanmiao copper deposit of Fengxian County is located in Tieluwan-Jiuzigou mineralized district of Qiandongshan-Weiziping-Tongpaigou Cu-Pb-Zn polymetallic mineraliza-tionbelt,south of Fengxian-Taibai ore-concentrated area.Mineralization zoning is clear from east to west of this area and metallogenetic conditions are favorable.Ore body occurs at the contact zone or nearby of Middle Devonian Gudaoling formation limestone and Upper Devonian Xinghong-pu formation phyllite,belonging to sedimentary-reformation deposit.Anticline,contact zone of limestone and phyllite,silication and pyritization are the main indicators for prospecting.Ore bodies including K1 and K2 are found in this deposit,in which silicified limestone is the main ore type,followed by silicified phyllite type,copper-bearing quartz-calcite vein type and siliceous rock type.Comparing with Jiuzigou copper deposit in the east of Fengxian county,they are in thesame ore-bearing position,prospecting should thus be based on transition and two wing twists of anticline and contact of limestone and phyllite,attention also should be paid to iron-carbonate veins of southern anticline and parallel to it.Combined with geophysical and geochemical anoma-ly,we can define optimal target and conductin-depth engineering test.Based on this exploration method and procedure,new prospecting break through is expected tobe madein Taishanmiao cop-per deposit.关键词
