乳山西涝口矿区成矿规律及找矿分析

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，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，由于地表矿化蚀变，使找矿工作较难开展，通过总结该区地质特征、矿床成矿规律，理清找矿思路，对下一步工作方向进行分析。

Metallogenic Regularities and Prospecting Analysis of Xilaokou Ore Area in Rushan

Xilaokou ore area is located in the northern edge of Jiao-Lai basin. The strata appeared in this area are Jinshan groups of early Proterozoic and Laiyang groups of Mesozoic. Magma rock is mainly formed in Yanshan period.The structures which have close relation with gold m ineralization are complex, and surface alteration can be found every where. It makes the prospecting work difficult.Through summarizing the geological features and ore-forming regularities, we put the prospect ing thinking in good order, and further prospecting direction is analyzed.
