| 摘 要： | 水系沉积物地球化学测量表明,攀枝花-西昌地区存在一个与峨眉山玄武岩分布范围基本吻合的P t,Pd区域地球化学异常,玄武岩中铂族元素丰度值普遍较高是一种正常的高背景现象,而峨眉山玄武岩中P t,Pd严重亏损或正异常显著的局部地区则显示出一定程度的成矿潜力。研究根据水系沉积物下伏基岩性质的不同,确定了不同地层单元和侵入岩类的P t,Pd背景值和异常下限,在研究区圈出多处P t,Pd衬值异常。结合有关铂族矿床以及同源玄武岩地球化学特征的认识,通过对水系沉积物P t,Pd综合异常的筛选,初步优选出铂族元素找矿远景区10个。

| Abstract: | According to the achievement of stream sediment geochemical surveys,there is a Pt-Pd geochemical anomalistic region in Panzhihua-Xichang area,south western China,which accords with the distribution of Emeishan basalts.It is a natural background that PGE content is high for basalts,local region where there is obvious depletion or remarkable positive anomaly for Pt and Pd in Emeishan basalts has some prospecting potentiality.According to the different bedrock underlying the stream sediments,the authors determined the background values and lower limit of the anomaly population of the Pt,Pd in the stream sediments based on different stratum unit or magmatic rocks type,and determined some Pt-Pd contrast anomalies in research region.Based on geochemical characteristics of Platinum group element deposits and basalts derived from the same origin,the authors screened Pt-Pd synthesis anomalies in stream sediments,and picked out 10 favourable prospecting region of looking for PGE deposits. |
