In view of inhomogeneous distribution of fluid pressure, fault-valve behavior and the coupled equations of the current density and fluid flow within the Earth's crust, especially, the observed anomalies in electrical field showed a similar pattern of rapid starting and slow decay, some of these anomalies associated with episodical spouting from borehole or the increase of fluid pressure in wells, it is reasonable to consider that the source of precursory electrical field anomalies is the streaming potential mechanism.

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。

Based on the regional tectonic evolution, combined with the high precision isotopic ages from this paper and other geologists, we have some new acquaintances as follows: 1 There has no Caledonian granite belt distributed in north margin of North China Craton. So, the traditional evolving model of North China Carton, which formed on this idea and the acquaintance about the collision of North China plate and Siberian plate, must be incorrect; 2 The age date show that the earliest magmatic activity began since late-Palaeozoic Permian, which is inconsistent with the previous idea that there were Caledonian and Hercynian active continental margin in the north of North China Craton and in the south Xingkai Massif. 3 the crust and lithosphere were thickened by the subduction and collision of Siberia plate and North China plate during Late Paleozoic. The magma is formed when the crust is heated and melts caused by thickened lithosphere delamination and caused the Asthenosphere upwelling. But only a little basaltic magma erupted, most magma underplate under the bottom of the crust. Thermal energy derived from basaltic magma underplating made the middle and lower crust melt partially and the late Permian-early Triassic granites is formed in large scale.

根据区域构造演化分析,并结合本文及他人高精度同位素年龄,我们对延边花岗岩形成的大地构造环境有了新的认识:1在华北地台北缘并不存在所谓的加里东花岗岩带,因此,建立在此之上的传统的华北地台北缘演化模式及有关西伯利亚板块与华北板块的碰撞拼合的认识也必然是不正确的;2华北地台北缘和兴凯地块南缘不存在加里东期和海西期花岗岩带,表明两地块边缘最早的花岗质岩浆活动始于晚古生代的二叠纪,即不存在传统观点所认为的加里东期或海西期活动陆缘;3晚古生代由于西伯利亚板块与华北板块的俯冲碰撞,致使地壳和岩石圈增厚,导致加厚岩石圈发生拆沉作用,使得软流圈上涌,加热地壳使之熔融形成岩浆,但玄武质岩浆少量喷出地表,大部分底侵于地壳底部,形成下地壳高密度的玄武质底侵层,玄武质岩浆底侵的热能引起中下地壳广泛部分熔融,形成大面积分布的晚二叠世—早三叠世花岗岩。
