| 摘 要： | 山东省宋家沟金矿位于胶莱盆地东北缘 ,产于莱阳群林寺山组断裂破碎带中。牟—即断裂带为切割莱阳群的断裂 ,对金矿起控制作用。早白垩纪晚期的火山—岩浆活动为深部含金热液的运移提供了通道 ,并在其有利的构造部位沉淀成矿。稀土元素特征和氧、硫同位素特征亦说明宋家沟金矿的物质来源以深源为主 (幔源及下地壳中的金 ) ,是早白垩世晚期的火山—岩浆活动作用的结果。

| Abstract: | Shandong Songjiagou Gold Deposit is loucated in the north-east edge of Jiaolai Basin where the fracture zone of Lisishan Formation, Caiyang Group appears. The ore is controlled by Mu-JI faulted zone which cuts Caiyang Group. The Glod-bearing hydrothermal solution moves up with the activies of early Cretaceous terminalvolcano-magma, and deposits in the favorable places. The lanthanon elements and sulfur and oxygen isotopic feature suggest that the ore materal comes from the deep place of Earth, and is related with the volcanic-magmatic activites in Cretaceous period. |
