| 中文摘要: |
| 甘肃红柳泉北山位于北山造山带南缘,处于小独山-白山堂钨-金(银)-铜(铅、锌)-铁-钼-铬-稀土-菱镁矿-萤石成矿亚带内。目前红柳泉北山已发现有铜多金属矿点6处。但总体勘查工作程度低,缺乏理论研究,找矿难以取得较大突破。近年来通过化探显示该区铜金等异常强烈,且区内构造运动强烈,岩浆活动频繁,显示了该地区良好的找矿地质条件。在分析1∶5万水系沉积物测量以及1∶1万土壤测量成果的基础上,重点剖析了与研究区成矿有关的乙类综合异常HS-18及与之相对应的次一级综合异常HT-8。并结合异常区地层、构造、岩浆岩及矿化特征等成矿地质条件,对找矿潜力进行了分析,以期对该区以及外围铜多金属资源找矿起到一定的借鉴作用。 |
| 英文摘要: |
| Hongliuquan Beishan is located on the southern edge of the Beishan orogenic belt, within the Xiaodushan-Baishantang tungsten-gold (silver)-copper (lead, zinc)-iron-molybdenum-chromium-rare earth-magnesite-fluorite metallogenic subzone. At present, six copper polymetallic deposits have been found in Hongliuquan Beishan. However, the overall level of prospecting work is low and theoretical research is lacking, making it difficult to make major breakthroughs in prospecting. In recent years, geochemical prospecting has shown that the copper and gold in this area are abnormally strong, and the tectonic movement in the area is strong, and magmatic activity is frequent, which shows the good prospecting geological conditions in this area. Based on the analysis of 1∶50,000 river sediment measurement and 1∶10,000 soil measurement results, this paper focuses on analyzing the type B comprehensive anomaly HS-18 related to mineralization in the study area and its corresponding secondary comprehensive Abnormal HT-8. Combined with the geological conditions of the formation, structure, magmatic rock and mineralization in the abnormal area, the prospecting potential is analyzed, in order to provide certain guidance and reference for the prospecting of copper polymetallic resources in this area and the periphery. |
