摘要:
通过古朔根乌拉地区1/5万矿调项目实施,共圈定1/5化探综合异常27个,新发现矿点两处,矿化点9处,矿种有金、铜、钼、银、铅、锌.通过对研究区成矿地质条件、1/5万化探综合异常特征、矿(化)点特征及分布等信息进行研究,阐明了该区成矿的时空分布规律和矿产的共生组合规律,划分成矿远景区4个,提交找矿靶区4个.对其中两处找矿靶区进行钻探验证,海勒斯特沟金锑多金属找矿靶区具有形成与岩浆活动关系密切的中-低温热液型金锑多金属矿的潜力,博和铜金多金属找矿靶区具有形成与中酸性侵入岩及后期岩脉有关的岩浆热液型-接触交代型铜多金属矿的潜力.
Abstract:
The project of 1/50000 Regional geological survey in Gushuogenwula area, worked by 514 Geological Team of North China Geological Exploration Bureau, got a good prospecting effect. 27 abnormal area of 1/50000 geochemical exploration were delineated, 2 new deposites and 9 mineralized spots with gold, copper, molybde-num, silver, lead, zinc were found. Based on the comprehensive study of metallogenic geological conditions, inte-grated anomaly characteristic of 1/50000 geochemical exploration, the characteristics and distribution of mineral occurrence, we understand the spatial and time distribution rules of the mineralization in this region, and then we divided the abnormal area into 4 metallogenic prospects and 4 prospecting targets. Through investigation, two of the target areas were verfied. The first one is in the Hailesitegou area with special of forming mesothermal-epith-ermal gold and antimony polymetallic deposit closly related to magmatic activity. The second one is in Bo he ar-ea with special of forming hydrothermal-contact metasomatic copper and gold deposit closly related to Mesozoic Era felsic intrusive rock and later stage dike rock.
