摘要:

西涝口矿区位于胶莱盆地北缘。出露地层主要有古元古界荆山群、中生界莱阳群地层,岩浆岩以燕山期活动为主。区内与金矿成矿关系密切的构造复杂多样,地表矿化蚀变随处可见,使找矿工作较难开展,通过总结该区矿床地质特征,把与金成矿关系密切的构造划分为层间滑动构造带及其上盘张性裂隙构造带2种主要类型,理清了找矿思路,对今后工作方向进行了探讨。

Abstract:

Xilaokou gold deposit is located in the northern edge of Jiaolai basin.The main strata are Paleoproterozoic Jingshan Group and Mesozoic Laiyang Group.Magma activity of Yanshan Period is the main.Th e structures relates to gold mineralization are complex.Surface mineralization and alteration can be f0und everywhere.it makes ore—prospecring dificult. By summarizing the geological feature of this area,The regional stru cture relates to gold mineralization can be divided into two types,namely interstratified sliding structure belt and tensile fracture belt of upper plate.The
ore—prospecting thinking is put in good order.Discussion on future exploration is carried out.
