Abstract:

豫西沙沟、铁炉坪和蒿坪沟银铅锌矿构成秦岭地区最大的银矿集区,初步探明银金属储量约4000t。在这3个矿区中矿脉群受NE向断裂的控制,单个矿脉仅数厘米到数十厘米厚,但延长达数千米和延深数百米,矿石银品位极高,是一种罕见的工业性矿床。本次研究在沙沟矿区的近矿蚀变岩中选取绢云母和铬云母进行40Ar/39Ar年龄测定,获得坪年龄为(145.0±1.1)Ma和(147.0±1.5)Ma,相应的等时线年龄为(145.2±2.5)Ma和(147.6±2.3)Ma。这些年龄数据与熊耳山地区的三道庄—南泥湖钼钨矿成矿年龄基本相同,鉴于在沙沟矿区银铅锌矿脉于深部钼矿化越来越强以及在邻区可见到围绕中生代花岗岩体发育的斑岩型_矽卡岩型钼钨矿及外围的脉状和破碎带型铅锌银矿的矿化分带之现象,可以认为银铅锌与钼钨矿化属于同一成矿系统。
