| 中文摘要: |
| 在1:5万水系沉积物测量的基础上，初步总结了茶庵铺地区地球化学特征。通过元素含量特征、变异系数等分析探讨了元素的成矿可能性，通过相关分析得出了多种元素组合，进而圈定了19处综合地球化学异常。AS10异常区经初步查证发现了3条较大规模的金多金属矿体。通过成矿地质条件和区域成矿规律分析，确定了沃溪式金多金属矿和沉积型钼钒多金属矿为主要矿产预测类型，圈定了3处找矿远景区。结果表明：水系沉积物测量方法在湘西地区有较好的金多金属矿找矿效果。 |
| 英文摘要: |
| Based on the 1:50, 000 stream sediment survey, the geochemical characteristics of the Chaanpu area were preliminarily summarized. The elements contents and variation coefficient were analyzed and the metallogenic potential of elements was discussed. The geochemical elements assemblies were identified by correlation analysis. As a result, 19 comprehensive geochemical anomalies were determined. Three Au-polymetal orebodies were found after preliminary exploration in the No. 10 anomaly area. The Woxi type Au- polymetallic deposit and the sedimentary type Mo- polymetallic deposit were identified as the important mineral prediction types, and the predicted prospective areas were determined according to the ore-forming geological conditions and metallogenic rules. The study results show that the stream sediment survey method can obtain ideal effects in prospecting of Au-polymetallic ore deposits in western Hunan Province. |
