龙口金矿区地球物化特征及控矿条件分析

Analysis of Earth Physical and Chemical Characteristics and Ore-controlling in Longkou Gold Field

龙口金矿区位于中生代胶莱盆地的东北缘,牟平—即墨断裂带为重要的区域性断裂,控制了本区基本的构造形态,使该区断裂构造整体呈北东走向。该区东北临辽上、蓬家夼金矿,东临西涝口金矿,金成矿条件较好。从地球化学、地球物理、构造等方面分析了该区金成矿地质条件,总结了找矿标志并对该区成矿远景进行了评价。

Longkou gold field is located at the northeast edge of Jiao-Lai basin in Mesozoic. Mo faulted zone is an important regional fault which controls the basic structure of this area and makes the fracture structure north-east trend. Gold deposits condition is fine for its position of near Liaoshang, Pengjiakuang gold deposit, and Xilaokou gold deposit. Geologic conditions of gold mineralization from the aspects of Geochemistry, physical geography, structure are analyzed, indicator is summarized and the prospective of mineralizing is evaluated
