    STUDY AND DETERMINATION OF Rb-Sr ISOCHRON DATING ON GOLD MINERALIZATION ALTERATION ZONE IN ZHAOYUAN-YEXIAN GOLD MINERALIZED BELT, EASTERN SHANDONG

      摘要
    • 摘要: 招-掖金矿带已得出三次金矿化的年龄。最早的一次金矿化发生在距今188.94±4.24Ma；第二次金矿化距今100.74±3.58Ma，这两次均属燕山期。最晚的一次金矿化发生在距今46.52±2.290Ma，当属喜山期。几次矿化年龄证明，招-掖金矿带的成矿作用是多次的，每次矿化又是多阶段的，可互相叠加。这充分反映了含矿热液的脉动性。矿体围岩蚀变是金矿化的同步产物，是一个锶均一化的封闭体系。用Rb-Sr等时线法测出其同位素年龄，即为一次金矿化的年龄。几条等时线给出的87Sr/86Sr初始比说明：招-掖金矿带成矿热液来源于大陆壳。
