Focusing on the PGE enrichment mechanism in the basic-ultrabasic intrusions in the Panxi rift, firstly, through the interpretation of TM photograph, data processing of regional geochemical exploration and geophysical prospecting results of gravity, magnetic force and seism, we analyzed the controlling effect of structure and magmatic movement on the PGE mineralization; Secondly, through the study of volcanic apparatus, petrography, measurement of comprehensive geochemical section, isotope tracing and dating of typical PGE-rich melanocratic rock series, we discussed the sources of the PGE-bearing mafic-ultramafic intrusions and basalts, their timing, evolvement sequences, the geochemical processes of magma crystallization and fractionation, and the relationship between magma evolution and structural development; Finally, through the analysis of PGE and chalcophile elements concentrations in the melanocratic rock series and the contrastive study with the Noril''sk magmatic Ni-Cu-PGE sulfide deposit, its related continental flood basalts and Siberia Traps, we discussed PGE mineralization characteristics and its enrichment mechanisms in the melanocratic rock series in the Panxi rift.

本项目首先围绕川西地区主要的PGE矿床及伴生矿的地质环境和有关的地质构造背景，通过TM卫片解译、区域化探和重、磁及地震物探资料分析，总体把握构造及岩浆活动对PGE成矿的控制作用；然后通过对典型富PGE暗色岩套的火山机构地质构造、岩石岩相学、地球化学、同位素定年和示踪等方面的工作，分析本区基性－超基性含矿岩体与喷出岩之间的成岩物质来源、侵入时代及演化序列，研究该区同一岩浆房分异结晶的地球化学过程及其随构造发展的耦合关系；最后通过对暗色岩套PGE地球化学剖面分析以及与俄罗斯诺里尔斯克陆内裂谷溢流型玄武岩中PGE矿化的岩石－构造环境对比研究，探讨该区暗色岩套中的矿化特点和富集部位及其PGE富集机制。
