NW断裂构造──鹅公山火山盆地铀矿成矿的关键要素

鹅公山火山盆地受郯庐断裂系影响，ＮＷ断裂构造尤为特色：张扭性，倾向ＮＥ，右行下滑，对盆地中３个铀矿床及绝大多数铀矿（化）点具明显控制作用，是铀矿成矿的关键要素。研究ＮＷ断裂对在鹅公山火山盆地及其它地区找矿都具有实际意义。     

南京湖山地区棒锤山纵向断层的发现及其地质意义

作者在野外数学中发现，棒锤山人工露头上存在一条重要的纵向断层，经研究认为、棒锤山纵向断层反映了汤－仑推覆体在其发展中至少存在两次明显的应力释放过程，它可能与两次大的构造推覆及应力集中有关。

时间剖面上小断层的计算机自动检测

煤田地震勘探一直探寻着对小断层的自动检测方法，因受各种因素的影响，至今尚无良策。本文介绍了多元地震参数的模式识别方法，并通过模型及实测资料成功地检测到１０ｍ以下小断层。     

武宁陆相红盆沉积特征与演化浅析

本文依据1:5万区调资料,扼要介绍了武宁陆相红盆填图单位的拟定、表示方法及工作原理的应用,重点叙述了红盆内多个冲积扇体特征及其之间的叠覆关系,阐明了盆缘断裂是控制红盆成生、发展演化的主导因素。对红盆成生及演化、时代也作了初步探讨。     

内蒙古西拉木伦断裂带韧性变形特征

西拉木伦断裂带在早二叠世末发生了韧性右行走滑，形成了包括韧性右行走滑带、韧性压扁带及弱韧性变形带在内的韧性变形带。据动力和运动分析，表明该韧性变形带为一普通剪切带，其中韧性右行走滑带在平面上以简单剪切为主，韧性压扁带在平面上以纯剪切为主。     

Radon,Lung Cancer Risk and Environmental Geology in Gejiu Area

The incidence of lung cancer in the Gejiu area of Yunnan Province ranks the first in the world.The radon level(indoor,soil) was measured in the Gejiu area by the SSNTD method from 1990 to 1996,The result indicates an extensive high-level of indoor radon in that area though U and Th are lower in local limestones,The indoor radon level of houses located in the geologic fault zone is 6 times high that 2km far from the fault zone.The reason probably is that the radon level of soil in the fault is 6-8 times high that 1 km far from the faults.our data indicate that a lower range of radon levels,0-100Bq.m^-3,exists in healthy families.However,a higher radon level,over 800 Bq.m^-3,is often found corresponding to that of cancer patients‘ homes(the house-owners are suffering from either lung cancer or leukaemia or liver cancer),Obviously,an increase in lung cancer incidence follows an increase in indoor radon level,The risk of cancer induced by indoor radon is no longer an inference,but a fact.     

甘肃桦树沟(铁)铜矿床的成因机制

矿床地质地球化学特征研究结果表明，随着古陆边缘弧－槽－盆体系的发生与发展，元古代基底火山（沉积）岩系经深循环水（海水）－热系统的作用，成矿物质被浸出和搬运，并经海底喷溢作用沉淀于海盆洼地中形成桦树沟矿床含铜建造，后期变质作用使成矿物质活化、转移和富集。桦树沟矿床为喷气（流）沉积－变质改造型（铁）铜矿床。     

The law of dislocation between two sides of active faults in China and their geodynamic force

By contrasting and analyzing the characteristics of gravity field nearby some important active faults in the continent of China, it can be found that the crust blocks where Bouguer anomalies are regionally positive (or relatively positive) are moving towards the terrestrial poles and the blocks where Bouguer anomalies in a tremendous area are negative (or relatively negative) are moving towards the equator. By analysis of mechanics and mathematics calculation and based on lots of practical data, the authors hold that the change in density of a crust block is a decisive factor that causes the horizontal movement of the continental crust, while magma activity is an important factor that leads to the change in density of a crust block.
