摘要
大平掌铜矿位于滇西澜沧江火山岩带的中南段,矿体呈层状、似层状赋存于泥盆纪-石炭纪的一套细碧-石英角斑岩系中,矿体具明显的“上层下脉”双层结构特征,即上部为块状矿体,下部为细脉-浸染状矿体。矿床为火山岩型块状硫化物(VHMS)特征矿床。矿石的金属矿物为铜-铅-锌-金-银矿物组合为主,矿化及蚀变具明显的分带性。沿矿区北西向控岩控矿构造带南北两端及西侧具有较好的找矿前景。
Dapingzhang Cu deposit is in the middle south section of W Yunnan Lancangjiang volcanic rock zone.The ore body is bedded,stratoid in the D-C spilit keratophyre series and with the clear 2 layers structure of“upper bed and lower vein”,ie upper massive orebody and lower veinlet dissemination orebody.It is the massive sulfide deposit of volcanic rock type(VHMS).The metal minerals are mainly in the assemblage of Cu-Pb-Zn-Au-Ag mineral.The metallogenesis and alteration zonation are clear.The good prospecting potentiality is in the S,N ends and W side of NW rock control and ore control zone of orefield.
