U—Series Dating of Fossil Bones：Results from Chinese Sites and Discussions on Its Reliability

Calculations,according to some open-system models,point out that while a statistically significant discrepancy between the results of two U-series methods,^230Th/^234U and ^227Th/^220Th(or ^231Pa/^235U),attests a relatively recent and important uranium migration,concordant dates cannot guarantee closes-system behavior of sample.The results of 20 fossil bones from 10 Chinese sites,19 of which are determined by two U-series methods,are given,Judging from independent age controls,8 out of the 11 concordant age sets are unacceptable,The results in this paper suggest that uranium may cycle into or out of fossil bones,such geochemical events may take place at any time and no known preserving condition may securely protect them from being affected.So for the sitew we have studied,the U-series dating of fossil bones is of limited reliability.     

中——高级变质相中水热流体的形成与作用

固体地壳中流体是普遍存在的，中－高级变质相中的矿物并非只发生晶体塑性变形，溶解和溶移作用在非糜棱岩化岩石中占主导地位，因为高温高压环境下存在的水热流体，在变质变形作用中起着至关重要的作用。在周围分布有网络状剪切带的递进缩短带中，与应变梯度有直接关系的单个矿物的位错密度梯度在其晶体边缘形成，产生了化学位梯度，从而使矿物边缘发生溶解，变形分解作用是产生这一过程的动力，并为流体汇聚成水热循环系统提供了空     

Important Geological Factors Controlling the Formation of Gold Deposits in East China

The major gold deposits in east China are characterized by their occurrence in pre-Cambrian host metamorphic rocks,restriction in some specific stratigraphic-structural terranes,tendentious localization in ductile or ductile-brittle shear zones,association with the syntexis type granitoids,and significant remobilization,superimposition and enrichment by the later stage Mesozoic tectono-magmatic activities.     

南海西南部人字形走滑断裂体系和曾母盆地的旋转构造

本文从一定地质时期内不同地块的活动和不同断裂的发育应在一个统一的应力系统下形成有序、配套的组合关系，它们的形成演化控制了该地区构造格局的观点出发，在南海西南部发现存在一个大型人字形走滑断裂系，由于曾母地块和南沙地块先后南移与西婆罗洲地块及其边缘增生带相碰撞，此人字形走滑断裂体系为一右旋体系。在人字形断裂间所挟持的曾母地块在渐新世－中新世时曾发生从向西南俯冲到向东南俯冲的逆时针旋转，从而在其西侧产生     

辽河岩群南北区域对比的新证据

根据辽河群杨树沟岩组叠层石指向研究，盖县亚岩群晚收缩阶段构造样式分析辽河岩群南北区域地层特征对比以及南北区域差异的原始沉积探讨四个方面，进一步说明南北辽河岩群是相变而不上，下关系。
