摘要
胶东地区晚中生代金矿床均有一个与岛弧玄武质、安山质岩浆相一致的δ3 4 S( 6 .5‰～7.0‰ )硫源 ,而金铜矿床的δ3 4 S为 4 .5‰～ 5 .0‰ ,与岛弧玄武质岩浆的δ3 4 S接近。可初步认为该区金 (铜 )成矿流体的热源来自地幔或俯冲地幔楔产生的玄武岩浆。成矿流体的产生与岛弧玄武质岩浆底侵 /内侵作用密切相关 。
The gold deposits have a sulfur δ 34 S of 6.5‰～7.0‰,which coincid e s the sulfur source of the arc basaltic-andesitic magma, and the gold-copper deposits have a sulfur δ 34 S of 4.5‰～5.0‰ which is closed to tha t of the arc basaltic magma in the late Mesozoic gold deposits of Jiaodong pen insula. It is believed that the thermal source of gold-copper ore-bearing fluid derived from mantle or mantle wedge dominating the basaltic magma, with the un derplating or intraplating, and the fluid is originated from the heated crust.
