岳家庄—虎头崖构造杂岩带金成矿地质条件及找矿预测

Geological conditions of gold mineralization and ore-prospecting prognosis in Yuejiazhuang-Hutouya tectonic complex rock zone

鲁西地区是我国著名的花岗—绿岩带分布区,金成矿与之关系密切。其中岳家庄—虎头崖构造杂岩带为重要的多金属成矿带,泰山岩群花岗—绿岩带为金成矿主要矿源层,退变质带和燕山期岩体的边部为主要赋矿部位。金异常沿NW向构造展布,金矿化严格受构造控制。该构造杂岩带成矿条件良好,是金成矿的有利靶区。

The area of granite-greenstone belt in west of Shandong is famous in china, it correlates closely to gold mineralization. In this area, Yuejiazhuang-Hutouya tectonic complex rock zone is important metal complex mineralization belt, the Taishan group granite-greenstone belt in this area is the main stratum containing gold, the degenerating metamorphism belt tectonic,and the side of Yanshan rock mass are the main occurrence area of orebody. The gold anomaly spreads along NW direction, and the gold mineralization is controlled by constitution. This structure complex rock zone is good in gold mineralization condition, this advantageous prospecting target area.
