摘　　要：为了研究广西龙川地区的水系沉积物地球化学特征和找矿潜力,在该地区开展1∶5万水系沉积物地球化学测量,通过对2111个样品分析结果进行统计分析,综合研究元素地球化学特征参数、元素平均含量地球化学分布特征及元素异常特征,圈定了11处水系沉积物综合异常。依据水系沉积物综合异常圈定及解释推断,结合本区矿产分布情况、成矿地质背景及区域成矿规律等,划分出了4个微细粒型金矿找矿远景区。并对找矿远景区找矿潜力进行分析,初步建立了研究区内微细粒型金矿地质-化探综合找矿方法。In order to study the geochemical characteristics of water system sediments and mineral prospecting potential in Longchuan area of Guangxi,we conducted a 1∶50,000 geochemical measurements of water system sediments in the area.By statistically analyzing the analysis results of 2111 samples of water system sediments and comprehensively studying the characteristic parameters of elemental geochemistry,the geochemical distribution characteristics of the average content of elements and the characteristics of elemental anomalies,11 comprehensive anomalies of the water system sediments were identified.Based on the comprehensive anomaly definition and interpretation of the water system sediments,combined with the distribution of minerals in the region,the geological background of the mineralization and the regional metallogenic patterns,4 prospecting areas for micro-fine grained gold ores have been delineated.We have analyzed the prospecting potential of the prospect areas,and preliminarily established a comprehensive geological-chemical exploration method for the micro-fine grained gold mines in the study area.
