摘要:
丝毛岭金矿床位于陕西凤太多金属矿集区的西北部,产于NWW 向脆韧性剪切构造带中,矿体赋存于丝毛岭向斜北翼上泥盆统星红铺组的斑点状铁白云质粉砂质千枚岩。金矿化类型包括蚀变岩型和石英脉型两种,成矿过程可划分为早、中、晚3个阶段。对其早期成矿阶段热液蚀变形成的绢云母开展40Ar/39Ar测年研究,获得其坪年龄为(211.9±1.5)Ma,指示其成矿作用始于211.9Ma左右,即晚三叠世。结合前人有关区域地质与多金属成矿作用的研究成果,认为丝毛岭金矿床与凤太矿集区中的八卦庙柴蚂、双王等金矿床一样,都属于造山型金矿床,它们是中、晚三叠世—早侏罗世时期位于东古特提斯构造域中的南秦岭碰撞造山带大规模构造-岩浆-流体活动的产物。
