摘　　要：为了研究广东省思贺地区的水系沉积物地球化学特征和找矿方向,在该地区开展了1:5万水系沉积物测量。通过对采集的2248个样品分析结果进行统计分析,分析了Sn、Cu、Pb、Zn等成矿元素在空间上的分布特征。依据思贺地区的地球化学异常特征、元素组合以及控矿地质条件、成矿规律、矿产分布情况,预测了该区的找矿方向,共划分了5处找矿远景区。通过异常查证,在羊笪和横岗等地分别发现了铜钼和锡矿体,为矿产勘查提供直接的目标。In order to study the geochemical characteristics of stream sediments and prospecting direction in Sihe area,Guangdong Province,150000 stream sedimentary survey is carried out in this area.Through the statistical analysis of the analysis results of 2248 samples,the spatial distribution characteristics of Sn,Cu,Pb,Zn and other ore-forming elements are analyzed.According to the geochemical anomaly characteristics,element combination,ore-controlling geological condition,metallogenic regularity and mineral distribution in Sihe area,the prospecting direction of this area is predicted,and five prospecting areas are circleded out.Through anomaly verification,copper-molybdenum and tin ore bodies are found in Yangda and Henggang area,respectively.It provides the prospecting target areas for mineral exploration.
