摘要
通过龙沟河-鲜花山地区1:5万水系沉积物测量工作,获得了较丰富的区域地球化学测量成果.利用变异系数、浓幅分位值、相关性和异常特征研究对11种元素进行了数理分析,分析元素的地球化学特征,发现Au、Ag、Mo、As、Sb为主成矿元素.结合异常分布和元素成矿特征优选出了2处成矿远景区,经槽探验证,双目咀金锑成矿远景区发现2条金矿化体.
The geochemical characteristics of Longgouhe-Xianhuashan area is studied on the basis of the 1：50 000 stream sediment survey. With large amounts of regional geochemical data, the author carries out a mathematical analysis for 11 elements by variation coefficient, concentration quantile and anomaly characteristics. It is found that Au, Ag, Mo, As and Sb constitute the major ore-forming elements. Based on the anomaly distribution and metallogenic characteristics, two prospective areas for mineralization are optimized. With verification by exploration and surface work, two gold mineralization bodies are discovered.
