The unit bottom was the unconformity developed by Wuling Movement, and the unit top was overlapped by glacial deposition of Nanhua System. What\'s more, an unconformity can be found in Northern Guizhou and North-western Hunan. At the same time, this boundary was an important transformation between different deposition types: Banxi Group was rift basin deposition with flysch suite, and bearing a vast amount of pyroclasts, and this suggests that there was strong activity of crust. But the overlapping glacial deposition stood for steady deposition with penecaprock characteristic, and under unique climate environment.

下为武陵运动形成的角度不整合面所限；其上被南华冰期沉积所超覆，在黔北—湘西北可见角度不大的不整合，而且这一界面是两个不同沉积类型或建造之间的一个转换：板溪群为具有复理石韵律的裂谷系充填，其中发育大量火山碎屑沉积，显示较强的地壳活动性；而上覆的南华冰期沉积所代表的是一个具有准盖层性质的、独特气候环境下的稳定沉积。

Based on field work in fourteen typical ore districts of China, the author made experiments on contact metasomatism of ultrabasic-acid intrusive rocks with carbonate rocks, interaction between volcanic pneumatolyto-hydrothermal solution and volcanic rocks, and metasomatism in the process of sedimentary metamorphism and migmatizatiun.

Heilongjiang mélange distributed in Yilan area of Heilongjiang Province is regarded as the tectonic mélange with features of suture zone. Some metam orphic basic lavas consisting of quite a few metamorphic minerals without directional characteristics are named massive blue schist.

黑龙江省依兰地区分布的黑龙江杂岩被认为是具有缝合带性质的构造混杂岩，其中所含变基性火山熔岩中含有的变质矿物不具有定向组构特征，因此称之为块状蓝片岩。

The Late Paleozoic volcanic rocks widely outcropped in the south margin of the Altai Mountains, in which the Middle Devonian Beitashan Formation consists of a series of volcanic-sedimentary rock predominated by intermediate-basic volcanic with rare picrite and ankaramite at the base.

阿尔泰山南缘晚古生代火山岩十分发育，其中中泥盆世北塔山组为一套以中基性火山岩为主的火山－沉积岩系，并且其下部发育少见的苦橄岩和富辉橄玄岩。

In particular, a period of rifting /relative sea-level fall occurred in the late Givetian-early Frasnian and resulted in the reactivation of basement lineaments as normal faults, basic volcanism and subaerial exposure in much of Novaya Zemlya.

尤为特别的是，中泥盆世晚期至晚泥盆世早期曾发生一个时期的断裂/相对海平面下降，从而造成了底层线型构造再生为新地岛大部的正断层、基性火山活动和地缘暴露带。

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。
