山东山后金矿床构造控矿规律及找矿预测

山后金矿是武警黄金第七支队在招平成矿带上发现的又一处金矿床,探明金资源量超过20 t。通过研究区域地质背景,从遥感解译构造与成矿的关系、不同期次断裂对金矿体的控制、断裂性质对工业矿体定位的控制、断裂形态产状的变化及破碎程度对工业矿体定位的控制和断裂的规模对工业矿体定位控制5个方面总结了山后金矿构造控矿规律。同时,对构造应力场转换、成矿作用及成矿系列进行了分析研究,认为该区金成矿与构造关系密切,断裂交会、分支和复合等部位是成矿有利地段。

The Structural Ore-controlling Regularity and Prospecting Prediction of Shanhou Gold Deposit in Shandong Province

Shanhou gold deposit is another gold deposit discovered in Zhaoyuan-Pingdu metallogenic belt by No.7 Gold Geological Party of CAPF,at present,the gold resource extent proved has exceeded 20 t.Based on studying regional geological background,we sum up the structural ore-controlling regularity from five aspects,such as the relation of remote sensing interpretation structure and mineralization,the fault at different periods controls the gold orebody,fault characteristics controls the location of commercial orebody,the change and broken degree of fault pattern occurrence controls the location of commercial orebody.At the same time,by discussing and researching the transformation of tectonic stress field,mineralization and metallogenic series,we think that the gold mineralization is close to structure,the intersection,branch and composite of the fault are good for mineralization.
