| 中文摘要: |
| 对于浅覆盖区或基岩出露差的地区,综合物探是区域地质调查和远景区找矿等工作中不可或缺的技术手段,方法搭配得当可达到优势互补,相互印证的效果。依托内蒙古东部大兴安岭北段乌音呼日勒庙等4幅区域地质矿产调查项目的开展,综合物探工作开展了地面高精度磁测和大功率激电；工作是在优选面积性化探异常的基础上,以大比例尺地、物、化综合剖面的形式展开的；物探控制性剖面在布日罕特银多金属矿点和山登脑银钼多金属矿点均发现磁、电异常；经山地工程查证,磁、电异常由构造蚀变矿化带引起；沿矿化带又陆续发现多处多金属矿(化)点。综合物探方法可以为在残坡积层和草原植被严重覆盖条件下的区调和矿调工作提供范例。 |
| 英文摘要: |
| For shallow cover or poor bedrock exposed areas, integrated geophysical prospecting technology is indispensable method for regional geological survey and exploration inprospective area. With proper method collocation, effects of complementary advantages and mutual verification can be achieved. Supported by the launch of geological and mineral investigation project in four regions like WuyinhurileMiao, situated in the northern section of Great Khingan Mountains in the east of Inner Mongolia, high-accuracy ground magnetic survey and high-power induced polarization have been invested in this integrated geophysical prospecting. The work was carried out by the way of large-scale generalized section in geological, geophysical and geochemical exploration, based on optimizing previous geochemical exploration anomalies.The section of geophysical survey has captured magnetoelectricity anomalies in Burihante silver polymetallic mineralized occurrences and Shendengnao silver and molybdenum polymetallic mineralized occurrences.These geophysical anomalies werecaused by structural alteration mineralization zone verified by exploration engineering. A number of polymetallic mineralized occurrences have been gradually found along the mineralization zone. This integrated geophysical prospecting will provide forceful guidance for regional geological survey in the severely covered area withresidual slope sediment and grassland vegetation. |
