元谋地区超基性岩浆型铂钯矿成矿作用探讨

摘要

Sichuan-Yunnan new rifting is acompanied by strong magmatic activity. In addition to voluminous effused basaltic magma flow basic intrusion with Pt-Pd deposit occur at Zhubu and Heinipo. Combined with geological characteristics of Yuanmu area metallogenic model of Pt-Pd deposit in the ultra-basic intrusion is put forward on basis of analysing soil and rock geochemical characteristics of the ultra-basic intrusion.%川滇新裂谷作用伴有强烈的岩浆活动,除大量玄武质岩浆喷溢外,在元谋朱布、黑泥坡等地见超基性岩体侵入,赋存有铂钯矿床.文章通过分析黑泥坡、朱布超基性岩体的土壤地球化学特征和岩石地球化学特征,结合元谋地区地质特征,提出了元谋地区超基性岩体铂钯矿床的成矿模式.
