山东莱西山后金矿床地质特征及找矿前景分析

山后金矿床位于招平成矿带的中南部，为破碎带蚀变岩型金矿床，矿体严格受断裂构造控制，矿体埋藏深度大，具有多期次多阶段叠加成矿的特点。围岩蚀变主要为钾化、硅化、绢云母化、碳酸盐化等，具有水平分带现象，在矿体周围能形成异常的元素有Au、Ag、Cu、Pb、As、Sb、Bi、Mo等元素，在平面、剖面上，异常元素组合齐全，强度大，浓度分带明显的部位，是矿体最易形成部位。综合地质、地球化学、地球物理特征表明深部找矿前景巨大。

Geological features and prospecting potential of Laixi Shanhou gold deposit in Shandong

Shanhou gold deposit locates in the central and southern part of Zhaoping metallogenic belt. It is a fractured belt altered rock-type gold deposit, and the orebodies are strictly controlled by faults. The orebodies buried deeply with characteristics of multi-stage and superimposed mineralization. Wall-rock alterations are mainly potassium, silicification, sericitization, carbonatization and so on, with horizontal zonation. There are abnormal elements such as Au, Ag, Cu, Pb, As, Sb, Bi and Mo around the orebodies. The compounding.of abnormal elements is com- plete in the plane sections and the intensity is high. The orebodies are easy to form in the areas where the concentra- tion zonation is obvious. The geological, geochemical and geophysical characteristics indicate that there is great pros- pecting potential at the deep part.
