柯树背岩体的副矿物特征及地质意义

本文详细研究了柯树背岩体的岩石学及副矿物学特征，研究发现F9大断裂以西部分(西体)与F9大断裂以东部分(东体)在岩性、矿物组成、副矿物特征、锆石群型特征上存在很大差别，副矿物特征、锆石群型特征指示东体与寨背岩体类似，为同熔系列花岗岩；西体为重熔再生岩浆成因的改造型花岗岩。这一认识对于该区的铀金找矿具有一定的指导意义。

含油气盆地构造样式研究中几个问题的讨论

对我国含油气盆地构造样式研究中存在的一些主要问题进行了讨论。包括：关于构造样式的确切含义及类型的划分，由于对构造样式概念理解的不一致，导致了构造样式类型划分的混乱；构造样式的鉴别，往往由于过分强调了某些单一“鉴定标志”而忽略了总体变形特征，从而导致对构造变形机理的错误判断；中国含油气盆地的构造反转问题。     

华北地台北缘东段多期褶皱及构造置换对鞍山群铁矿床的控制作用

多期褶皱和构造置换是华北地台北缘太古宙鞍山群岩石中的主要变形特征，也是对太古宙鞍山群铁矿的形态、规模、产状和分布规律的主要控制因素。     

塔里木及邻区晚古生代早期古气候与构造

影响塔里木及邻区晚古生代早期气候的地球内部因素为古昆仑和南天山两个古洋盆封闭及有关的两条缝合构造带演化，从而形成上述时空段内热带海洋气候、热（亚热）带季风气候、热带沙漠气候以及热带滨岸干湿气候区域的更替，古气候特征的判断主要依据古地磁数据、古生态气候学、沉积环境诸方面。     

Structural studies and their bearing on the Early Precambrian history of the Dharwar tectonic province,southern India

In the Dharwar tectonic province, the Peninsular Gneiss was considered to mark an event separating the deposition of the older supracrustal Sargur Group and the younger supracrustal Dharwar Supergroup. Compelling evidence for the evolution of the Peninsular Gneiss, a polyphase migmatite, spanning over almost a billion years from 3500 Ma to 2500 Ma negates a stratigraphic status for this complex, so that the decisive argument for separating the older and younger supracrustal groups loses its basis. Correlatable sequence of superposed folding in all the supracrustal rocks, the Peninsular Gneiss and the banded granulites, indicate that the gneiss ‘basement’ deformed in a ductile manner along with the cover rocks. An angular unconformity between the Sargur Group and the Dharwar Super-group, suggested from some areas in recent years, has been shown to be untenable on the basis of detailed studies, A number of small enclaves distributed throughout the gneissic terrane, with an earlier deformational, metamorphic and migmatitic history, provide the only clue to the oldest component which has now been extensively reworked.     

山东文登金矿成矿动力学研究

本文通过古应力估算，流体包体研究，应变测量以及矿化蚀变规律研究，探讨了山东文登金矿的动力作用与金成矿的主要关系，认为构造动力作用的金成矿的主要原因，韧性剪切作用向韧－脆性变形作用的过渡过程是金成矿的必要条件之一。     

晋南地穹列煤层气赋存区构造应力分析

根据晋南地穹列构造型相分析，恢复了4期应力场：①地洼初动期（印支期）近S－N水平挤压；②地洼激烈期（燕山期）NWW－SEE水平挤压；③地洼余动期（喜山早期）NNE－SSW水平挤压；④地洼余动期（喜山中期）NW－SE、NWW－SEE近水平伸展。其现代构造应力场以NW－SE向伸展应力场为主，但在沁水地穹则表现为NEE－SWW向近水平挤压应力场。有限元模拟分析证实：此局部挤压应力场的动力来源于挽近地质时期太行山和霍山的隆起与抬升，临汾地洼和太原地洼中的伸展应力场则与地洼壳体下部慢源物质逸散所导致的侧向拉伸有关。区内应力降的分布特点与晋南地穹列断裂构造发育程度具有良好的对应相关性，在高应力降区，单位体积煤层气含量显著高于其它地区。模拟主应力差等值线图中两个高主应力差值区恰好与东部沁水地穹中两个高含气量区相对应，充分说明地洼余动期构造应力场中高压应力区是煤层气富集的有利地区。     

Separate Analysis of Remote Sensing Information of Structures of Different Geological Periods and Quantitative Study of Corresponding Tectonic Stress Fields

The structural feature shown on a remote sensing image is a synthetic result ofcombination of the deformations produced during the entire geological history of an area.Therefore, the respective tectonic stress field of each of the different stages in the complexdeformation of an area can be reconstructed in three steps: (1) geological structures formed atdifferent times are distinguished in remote sensing image interpretation; (2) structuraldeformation fields at different stages are determined by analyzing relationships betweenmicrostructures (joints and fractures) and the related structures (folds and faults); and (3)tectonic stress fields at different stages are respectively recovered through a study of the featuresof structural deformation fields in different periods. Circular structures and related circlular and radial joints are correlated in space to con-cealed structural rises. The authors propose a new method for establishing a natural model ofthe concealed structural rises and calculating the tectonic stress field by using quantitative dataof the remote sensing information of circular structures and related linear structures.
