摘要
利用攀枝花幅(永仁幅)、会理幅、盐边幅、米易幅、盐源幅和西昌幅共6个1:20万图幅的区域铂、钯地球化学资料,运用了数据滤波处理方法圈定铂族元素异常.讨论了水系沉积物中铂、钯地球化学背景和异常与峨眉山玄武岩、基性-超基性岩等地质体的空间关系,并做了该地区铂族矿产的找矿远景预测.
Panzhihua-Xichang area is one of the potential regions for PGE deposits in China, because of its good PGE ore-forming geological backgrounds. Geochemical data from six 1：200 000 maps of Panzhihua （Yongren）, Huili, Yan- bian, Miyi, Yanyuan and Xichang sheets are adopted and treated by means of data-filter to delineate PGE anomalies. The geochemical background and anomalies of Pt and Pd in stream sediments are studied. The relation of their distribution to the Emeishan basalts is also discussed. The prospecting targets for PGE deposits in the area is predicted.
