| 中文摘要: |
| 土壤地球化学测量在实际找矿中有广泛的运用，效果显著。本文通过开展广东龙门平陵径—大坑迳地区的1∶2.5万土壤地球化学测量及异常查证工作，基本查明了区内土壤中W、Sn、Bi、Mo、Cu、Pb、Zn、Ag、Au、As、Sb共11种元素的含量特征以及元素分布形态和组合特征。综合分析该区成矿地质条件和地球化学信息，认为区内主要成矿元素为Ag、Bi、Sn、Pb、Sb、W、As，圈定了有价值的地球化学综合异常HT1~HT4共4处。经异常查证，圈定了有望获得找矿突破的有利靶区2处，其中HT1综合异常预测为矽卡岩型铅锌多金属矿，HT4综合异常预测为石英脉型钨锡矿。本次研究通过对平陵径—大坑迳地区土壤地球化学特征及成矿地质条件的深入分析，进行了成矿预测，为区内下步找矿工作提供了找矿方向和有利靶区。 |
| 英文摘要: |
| Based on 1∶25，000 soil geochemical survey and anomaly verification in Pinglingjing-Dakengjing area of Longmen Basin， Guangdong Province， the content， distribution patterns and combination characteristics of 11 elements including W， Sn， Bi， Mo， Cu， Pb， Zn， Ag， Au， As and Sb in the soil were basically identified. Comprehensive analysis of metallogenic geological conditions and geochemical information in this area shows that the main metallogenic elements in this area are Ag， Bi， Sn， Pb， Sb， W and As， and four valuable comprehensive geochemical anomalies HT1-HT4 are identified. After anomaly verification， two favorable target areas which are expected to obtain prospecting breakthrough are identified， among which HT1 comprehensive anomaly prediction is skarn-type lead-zinc polymetallic deposit and HT4 comprehensive anomaly prediction is quartz-vein type tungsten-tin deposit. Based on the in-depth analysis of the soil geochemical characteristics and metallogenic geological conditions in Pinglingjing-Dakengjing area， the metallogenic prediction is made， which provides the prospecting direction and favorable target area for the next prospecting work in this area. |
