Abstract:

文章首次对冈底斯成矿带的甲马和知不拉铜_铅_锌矿床的辉钼矿进行了Re_Os同位素定年。甲马矿区辉钼矿的模式年龄介于15.4~15.5Ma之间,7件样品得到187Re-187Os等时线年龄为(15.18±0.98)Ma。知不拉矿区辉钼矿样品的模式年龄介于16.88~17.06Ma之间,5件样品得到187Re-187Os等时线年龄为(16.90±0.64)Ma。获得的Re_Os年龄与冈底斯成矿带驱龙、拉抗俄和冲江、厅宫等斑岩铜矿床的成矿年龄一致,明显晚于侏罗纪拉萨弧间盆地的发育时限。据此作者认为甲马和知不拉等铜_铅_锌矿床不属于喷流型矿床,而是冈底斯成矿带斑岩_矽卡岩成矿系统的组成部分,是岩浆_热液流体系统在不同的深度条件下与富钙围岩交代成矿的产物。
