| 中文摘要: |
| 中深部隐伏矿(化)体是当前地质找矿的重点勘查对象。研究区地层简单,多数为第四系覆盖,在已圈定出的区域化探异常范围内,通过地物化综合方法手段进行勘查,目的是发现并圈定出矿(化)体赋存部位,取得深部找矿的突破。该区位于上黄旗—乌龙沟银多金属成矿带,是冀北地区有色金属矿产的重要聚集区,成矿条件十分有利。本次工作在地表圈出的化探、激电中梯异常范围内,通过激电测深测量以及地质山地工程的揭露,验证了矿(化)体的存在,取得较好的找矿效果。由此表明地物化综合勘查技术对隐伏矿(化)体预测定位是行之有效的。 |
| 英文摘要: |
| Predicating concealed ore bodies at the depth is the focus of the current geological exploration target．The strata in the studied area is relatively simple, mostly covered by Quaternary sediments. The comprehensive geological, geophysical and geochemical methods in the anomalous area outlined by the regional geochemical survey were applied to discover the concealed ore bodies and delineation of orebody location. The studied area is located in the Shanghuangqi-Wulonggou silver polymetallic metallogenic belt,which is the important non-ferrous metals mineralization concentration area in the northern Hebei,where metallogenic conditions are very favorable.By applying IP method combined with geological approach and test engineering works, the orebodies (mineralized bodies) were discovered at the depth in the outlined anomalous area by geochemical survey and IP survey. The successful discovery has proved that the application of comprehensive prospecting technology in forecasting the concealed orebodies the most effective method． |
