摘要
皖南宁国竹溪岭钨钼银多金属矿床位于江南造山带东南缘的北东部,是近年来新发现的一个大型钨多金属矿床。矿体主要产于燕山期黑云母花岗闪长岩与震旦系兰田组灰岩接触带。矿区W、Mo矿体可划分为矽卡岩型W、Mo矿体,石英硫化物脉型W、Mo矿体和蚀变花岗闪长岩型W、Mo矿体,而以矽卡岩型W、Mo矿体为主要矿体;银矿体主要为石英脉型矿体。矿石矿物主要有白钨矿、辉钼矿、黄铁矿、闪锌矿、方铅矿、辉银矿、碲银矿等,脉石矿物主要为石榴子石、透辉石、透闪石、石英等。矿体呈似层状、脉状产出。矿床成因类型属矽卡岩型钨钼银多金属矿床,控矿因素主要有震旦系地层、燕山期岩浆岩和近东西向断裂构造,找矿标志包括岩浆岩、地层、构造、蚀变、矿化等。研究区具有重要的找矿潜力。
The Zhuxiling W-Mo-Ag polymetallic deposit in south Anhui province is a giant deposit discovered within the Jiangnan orogenic zone and adjacent areas in recent years.The orebody was generated in skarn which formed in the contacted zone between the Yanshanian biotite granodiorite and limestone of the Sinian Lantian Formation.W,Mo orebodies can be divided into skarn type,sulfide quartz vein type and altered granodiorite type.The skarn type W and Mo orebody is the main orebody of the deposit.The Ag orebody is quartz vein orebody.The main ore minerals are scheelite,molybdenite,pyrite,sphalerite,galena,argentite,hessite,and gangue minerals are garnet,diopside,tremolite,quartz etc.Tungsten polymetallic orebodies occur in stratiform or vein.The deposit belongs to skarn tungsten-molybdenum-silver polymetallic deposit.The ore-controlling factors are:Sinian strata,Yanshanian magmatic rock,and the approximate east-west fault factors.The prospecting marks include magmatite,stratigraphic and lithologic,structure and mineralization alteration,etc.The study area has important ore prospecting potential.
