莱州新立金矿床的发现及其地质特征

DISCOVERY OF XINLI GOLD DEPOSIT IN LAIZHOU AND ITS CHARACTERISTICS

摘要:

新立金矿床地处渤海莱州湾畔，含矿蚀变带隐伏于海水之下，矿床位于三山岛断裂带（主要控矿断裂）由ＮＥ向转为ＮＥＥ向的拐弯部位。三山岛、仓上金矿床也分布在该断裂带拐弯地段。根据胶东地区金矿主要受ＮＥ向断裂控制，构造产状变化或构造交汇部位易于成矿，以及金矿床具有等距分布的特点，今后找矿的重点地段应是仓上金矿床北部和芙蓉岛—潘家屋子一带。

Abstract:

Xinli gold deposit located in the Laizhou bay of Bohai sea and the ore-bearing altered belt hidden under the sea. The deposit lies in the turning part of Sanshandao fault from NE to NNE which is as the same as the other two discovered and evaluated deposit′s distribution in the faults, that is Sanshandao and Cangshang deposits. According to the equally-spaced distribution regulation of gold deposits along faults in Jiaodong area, it is predicated that the north part of Cangshang gold deposit and Furongdao-P...
