内蒙古库伦旗拉民稿金多金属矿化区成矿地质特征及找矿方向

拉民稿金多金属矿化区位于通辽市库伦旗西南部拉民稿地区,根据野外地质调查结果,在矿区圈出金多金属矿化带四条（PS1、PS2、PS3、PS4）,采样含金品位一般为（0.11-7.48）×10-6,最高为13.56×10-6,含银最高品位为92.5×10-6。钻孔中圈出矿体可分三类：灰岩（见黄铁矿化、硅化）、板岩（见黄铁矿化...

Geological features and prospecting directions of LaMinGao Gold polymetailic mineralized area in KuLun, Inner Mongolia

LaMinGao gold polymetailic mineralized area is located in the southwest of KuLun, TongLiao city. In the mining area differentiate in four gold polymetallic belts (PS1、PS2、PS3、PS4) , according to the field geological survey results. The gold contents of the samples range commonly from 0.11×10-6 to 7.48×10-6, the highest is 13.56×10-6, the highest contents of silver is 92.5 x 10-6. It can be divided into three kinds of ore bodies in drilling: Limestone(produced pyritization, siliconization), Slate(produced pyritization, siliconization), Andesites including breccia(produced pyritization, siliconization, ferritization). In the surrounding rock(Limestone and Slate), the gold contents of the drilling samples range commonly from 0.11×10-6 to 4.30×10-6, the highest is 8.59×10-6, the highest contents of silver is 165 x 10-6. The gold contents of the drilling samples in Andesites including breccia range commonly from 0.12×10-6 to 6.69×10-6, he highest contents of silver is 27 x 10-6. Comprehensive research shows that magmatic hydrothermal activity provides the material, fluid and power source for gold polymetallic mineralized belts, the part of northwest tectonic and northeast tectonic stack with each other is the position of the gold polymetallic body places for the output. LaMinGao gold polymetailic mineralized area has found gold polymetallic deposit metallogenic conditions.
