红外,紫外及荧光分析在有机包裹体研究中的应用

本文利用红外，紫外及荧光分析方法，对岩石中吸附有机质和包裹体有机质进行了分析研究，红外分析结果表明，生油岩中的包裹体有机质有明显的石油峰，并且与吸附有机质的峰形有较大差别，紫外分析结果也表明，生油岩中两种有机质的光谱性质不一致，而非生油岩则相反，生油岩荧光光谱特征为：荧光强度大（〉４０），λｍａｘ在４５０ｎｍ左右，光谱位于蓝绿光区，演化程度属高成熟原油阶段，这些可作为评价生油潜力，演化程度的方法及     

民和盆地上侏罗统湿型冲积扇沉积

本文通过岩相特征、粘土矿物分布、早期成岩矿物组合、微量元素等特征的综合分析，认为民和盆地上侏罗统下部为一较典型的湿型冲积扇沉积。冲积扇扇中发育河道冲刷充填和漫流沉积，而泥石流不发育。沉积层序与现代湿型冲积扇可对比。扇体中粘土岩及早期成岩矿物组合中富含高岭石，应与扇体发育时的潮湿气候和弱酸性流体的较强的淋滤有关。由粘土岩中微量元素因子分析进一步表明，该地层中富硼、钒的特征与相邻非扇相地层明显不同     

用土的分形结构确定土的水份特征曲线

运用筛析法和比重计法，分析了宁夏膨胀土的颗粒分布，发现粒径介于0．002～0．1mm的粒度分布是分形的，分维介于2．46～2．67；运用上孔隙分布的分维确定水份特征曲线，得到了很好的结果。此外，还探讨了粒度分形分布的机制。     

会昌浅层次热隆伸展构造与铀成矿

本文运用伸展构造理论对河草坑铀矿田的构造特征进行探讨，厘定出会昌浅层次热隆伸展构造是由伸展构造核、环形剥离断层系和断陷红盆所组成。对会昌浅层次热隆伸展构造的形成与演化作了研究。论述了伸展构造与区域铀成矿的关系，认为剥离断层活动为区域铀矿化准备了有利的构造环境；构造－岩浆作用是导致区内铀矿化和造成不同类型铀矿化特征基本相似的根本原因。     

相山铀矿田成矿作用的地球化学模拟

相山铀矿田是我国最大的火山岩型热液铀矿田，在地质地球化学和高温高压实研究的基础上，利用地球化学模式程序ＥＱ３／６模拟了成矿热水溶液的形成过程和减压排泄区铀成矿作用。计算机模拟结果表明，通过大气降水与碎斑熔岩相互作用，可以形成富含Ｆ和ＳｉＯ２等矿化剂的含铀热水溶液；由于铀以ＵＯ２Ｆ＾３和ＵＯ２（ＣＯ３（＾２－３等配合形式存在，非常稳定，即使在深部强还原环境中仍能能够迁移；酸性和碱性环境，尤其是强酸性     

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.     

Evolution model and formation mechanism of bio-thermocatalytic transitional zone gas

As a new genetic type of natural gas exploration area, the bio-thermocatalytic transitional zone gas (BTTZG) has been highly stressed by geologists both at home and abroad. Systematic study on the generation mechanism of hydrocarbon at the transitional zone is presented. Based on simulating experiments and geochemistry analysis of the source rock with lower evolution, a hydrocarbon-forming model at the transitional zone has been established. The mechanism is proposed that under the condition of low temperature and pressure combining with extremely active structural stress and clay mineral catalysis, BTTZG is formed by de-group of soluble organic matter and polarized compositions through orthocarbon ion as well as by condensation polymerization of aromatic ring-rich insoluble organic matter. This mechanism controls the formation of BTTZG, and furthermore, BTTZG is the product of superimposition and interaction of all the factors mentioned above.     

Evolution of Quaternary groundwater system in North China Plain

The Quaternary groundwater system in the North China Plain is formed mainly through the terrestrial water flow action on the united geological and tectonic backgrounds. The analysis of groundwater dynamic field, simulation of groundwater geochemistry, and the¹⁴C dating and extraction of isotope information have provided more evidence for recognizing and assessing the evolution of groundwater circulation system and studying the past global changes. The exploitation and utilization of groundwater on a large scale and overexploitation have given rise to the decline of regional groundwater level, change of flow field, decrease of water resources and downward movement of saline water body. The water environment has entered a new evolution stage in which it is intensely disturbed by the mankind’s activities. Project supported by the National Natural Science Foundation of China.     

华北地台东部寒武系层序地层年代格架

北地台寒武系属稳定的克拉通盆地陆表海沉积。其沉积层序表现为复合层序，主要受全球海平面变化和沉积物补给因素的控制。自下而上可划分为１７个正层序，归并为６个正层序组和２个中层序。大部分正层序的边界与生物地层单位一致，与岩石地层单位略有出入。每个正层序的平均时间延续约为３Ｍａ，含两个三叶虫化石带。根据层序地层的研究，可以建立华北寒武系层序地层年代格架，并提出各统和阶的界线参考年龄。     

福建晋江市前港湖、龙湖、虺湖等的地震堵塞成因研究

在国外前苏联学者尼可拉也夫曾提及地震后有的河流形成地震坝,其后再超覆沉积细粒物质,并称为"地震沉积相",显然这是指的地震堵塞湖形成后的沉积.国内最著名的地震堰塞湖是1933年四川省茂汶北的迭溪7.5级地震,这次强震不仅使迭溪全城及周围60余城镇、村寨全部毁灭,并且四山普遍崩溃,迭溪台地大规模崩塌、堵塞岷江,形成四个地震堵塞湖.大震后45天湖水溃决,造成下游水灾.类似这种地震堵塞湖是地震导致山地,丘陵或台地崩塌堵塞溪流,是地震导致的重力作用堵塞,应为地震重力堰塞湖.本文论及的地震堰塞湖即前港湖、龙湖、虺湖、丙州西侧小湖位于福建省晋江市龙湖镇西南侧,处晋江半岛中部,4个湖沿着控制深沪湾地堑北西边缘的衙口-丙洲断裂呈NE60°线状展布.该断裂与其东侧的深沪-金井断裂共同构成了全新世深沪湾地堑,卫星照片中有清晰的显示.这两条断裂及其所夹的活动地堑同属于区域性的常乐-诏安断裂带中段部份.
