摘要
龚家湾矿段与沃溪金锑钨矿、官庄金矿均位于沃溪大断层下盘的马底驿组赋矿板岩中,沃溪金锑钨矿位于仙鹅抱蛋穹窿NE倾伏端,龚家湾矿段位于两穹窿的凹陷对接处,官庄金矿位于明月山穹窿NW侧伏端,同处"两窿+断层"式独特的成矿构造格局中.文章分析钻探工程已经揭露到的龚家湾矿段V8S工业矿体及V8N蚀变层位,提出沃溪金锑钨矿十六棚公深部向斜轴及两翼,呈"牛腹式"以NEE71°方向,经过龚家湾矿段往官庄金矿延伸,推测两矿区连接部位的龚家湾矿段6～98线,NEE侧伏的矿体向斜轴部和南北两翼存在巨大的找矿潜力.
Abstract
Gongjiawan ore segement,Woxi gold-antimony-tungsten deposit,and Guanzhuang gold deposit are all located in Madiyi Formation ore-bearing slate in the footwall of the Woxi fault.Woxi gold-antimony-tung-sten deposit is located at the NE plunging end of the Xiangebaodan dome,Gongjiawan ore segement is loca-ted at the concave junction of the two domes,and Guanzhuang gold deposit is located at the NW plunging end of the Mingyueshan dome.Together,they form a unique ore-forming structural pattern described as"two domes plus one fault".The article analyzes the V8S industrial ore body revealed by drilling hole ZK13*2 and the V8N alteration zone revealed by drilling hole ZK6*1 in Gongjiawan ore segement.It is proposed that the deep part of the synclinal axis and both wings of the Shiliugongpeng area in Woxi gold-antimony-tungsten deposit extend in a'cow belly'shape towards the NEE direction at an angle of 71°,passing through Gongjiawan ore segement and extending towards Guanzhuang gold deposit.It is inferred that the Gongjiawan ore segement between prospecting line 6 and 98,which connects the two deposits,has a great exploration potential in the NEE-dipping ore body's synclinal axis and the north and south wings.
