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。

Fully considering the factors of structure, deposition, transforming system and Reservoir Forming Dynamics and so on, the paper thought that the reservoirs in Xiakou fracture zone belong to hydrocarbon remigration and secondary accumulation mode, the configuration relationship between the sands and faults is the main factor that affects hydrocarbon migration; reservoir gathers in the central upheaval zone belong to event hydrocarbon migration and accumulation mode, it can be divided into three styles, they are the fracture activity event mode, the volcanic activity event mode, he gravity flows event mode. The key factors of resulting in event reservoir are fault cyclicity and episodic characteristic.
充分考虑构造、沉积、输导体系和成藏动力等因素，分析认为：夏口断裂带油气藏聚集属于油气再运聚成藏模式，连通砂体与断层的配置是影响油气运移的主要因素；中央隆起带油气藏聚集属于油气事件成藏模式，划分为断裂活动事件成藏模式、火山活动事件成藏模式和重力流事件油气成藏模式三类，断层活动的旋回性和幕式性是诱发事件成藏的关键因素。

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。

TAS diagram for these three kinds of volcanogenic detritus, combined with variation diagram for Al2O, FeO(superscript *), MgO, CaO, Na2O, K2O vs SiO2, shows that there may exist bimodal volcanic activity in the north margin of the South China Sea, brown volcanic glass and colorless volcanic glass represent basic end member and acidic end member respectively, and crystallization differentiation is the main process for magma evolution.
在硅碱图及Al2O3、FeO、MgO、CaO、Na2O、K2O对SiO2，的变化趋势图中可以判断，本区可能存在双峰式火山活动，褐色火山玻璃代表中一基性端元，而无色火山玻璃代表酸性端元。无色火山玻璃与褐色火山玻璃具有共同的岩浆源区，结晶分异可能是源区岩浆演化的主要方式。

As there were no plate tectonics on the Moon, these mafic rocks are commonly regarded as products of hot-spot or mantle plume volcanisms.
由于月球上不存在板块构造，因此其基性火山活动是受热点或地幔柱构造所控制的。

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。

The favorable conditions for petroleum accumulation due to volcanic activity and igneous rocks formed during the activity show in two aspects. A The contact surface of igneous rocks and the surrounding sedimentary rocks, like a vertical unconformity surface, formed the conduit of petroleum migration.Petroleum would accumulate once it encountered a trap in which the reservoir had fine porosity and permeability. B It formed a trap barriered by igneous rocks, or changed or cut the original trap.
火山活动以及由此形成的火成岩体对油气聚集的有利条件主要体现在两个方面：一是沿火成岩与围岩的接触面构成油气运移的通道，火成岩与围岩接触，似一直立的不整合面，与孔渗性好的岩层组合不仅能使油气运移而且遇有圈闭油气还会聚集成藏；二是构成火山岩遮挡的圈闭，或是对原有圈闭进行改造、分割。
