摘要:
为了查明南秦岭镇安西部大型钨钼多金属矿集区成矿物质来源,在矿床基础地质研究的基础上,运用岩石地球化学、硫化物单矿物硫同位素地球化学和锆石U-Pb同位素、辉钼矿Re-Os同位素地球化学等方法,对复式中酸性侵入体与钨钼成矿的时空关系和成因联系进行深入研究。结果表明:懒板凳岩体田湾单元、王家坪隐伏岩体和花岗细晶岩脉富集Si元素,且Mg#值和稀土总量较低,稀土元素配分曲线呈明显的四分组效应并具有强负Eu异常,岩浆分异结晶程度高;懒板凳岩体九间屋单元和王家坪隐伏岩体锆石U-Pb同位素年龄分别为(222.7±2.6)Ma和(201.6±4.7)Ma,棋盘沟钨矿床和江口钼矿床中辉钼矿Re-Os同位素模式年龄分别为(199.7±3.9)Ma和(198.7±3.9)Ma;钨钼矿床中硫化物单矿物δ34S值为3.6‰~10.2‰,推测成矿物质来源于复式岩体晚阶段形成于190~200 Ma之间的高分异演化酸性侵入体。
