新疆阿拉尔花岗岩MFC过程的微量元素综合效应

新疆阿拉尔花岗岩的微量元素比相关图显示了线性样点列与幂函数曲线形式的样点列相 复杂图型。该图型用简单混合或者单一结果分异模型都不能解释。本文建立了混合－结晶分异复合过程的微量元素综合效应模型。模型１：从初始混合线引起害虫函数曲线束形式的结晶分异线。特殊情况有结晶分异线简化为通过原点的直线束形式或者与初始混合线重合。     

中国西天山拉尔敦达坂构造解析

拉尔敦达坂一带发育的大型复合式韧性剪切带，经解析分为水平拆离、挤压和岩浆侵入隆升、左行走滑韧性剪切三个不同阶段，变形时限分别限定在早古生代晚期至晚古生代早期、晚泥盆世和二叠-三叠纪。剪切带向东至伊连哈比尔山被“天山主干断裂”截断，向西经北本札尔特河谷的阿登布拉克沟在国境附近的阿拉爱格尔山口附近与邻国“尼古拉耶夫线”相接。该剪切带属南侧塔里木与伊犁-伊塞克两陆块碰撞缝合构造同碰撞期的次级构造带。     

Neural dynamic modelling on earthquake magnitude series

Earthquake magnitude prediction is of vital importance for human safety. The earthquake is a very complicated and non-linear dynamic process. It cannot be described adequately by any deterministic models. In this paper a neural dynamic modelling for earthquake magnitude prediction is reported. Historical records of earthquake magnitude series are used to construct the optimal non-linear dynamic model, and the consequent outcome of the earthquake behaviour is then predicted by this model. In turn, the latest recorded data set can be fed back to improve the accuracy of the neural dynamic model. The modelling of experiments of three earthquake magnitude series in China and Japan and their extrapolated predictions are included in this paper. The values predicted by extrapolation are in good agreement with the historical data.

乌鲁木齐河源冰川的消融强度函数

通过对天山乌鲁木齐河源１号冰川各物质平衡观测断面近１０年的观测资料和相应的气象资料进行统计分析，得出１号冰川东、西支消融期各月的消融强度函数。统计结果表明，消融强度与气温的关系随着月份的不同而异，同时由于１号冰川东、西两支冰川的朝向差异导致这一关系也有差别     

华北地台中寒武世米级旋四层序与复合海平面变化

笔者在对华北地区中寒武统颐滩碳酸盐建造露头层序地层学研究工作中首次识别出层序中最基本的地层单元──米级旋回层序，它是露头层序分析最基本的工作单元。本文总结概括出不同体系域内米级旋回层序类型和特征。这些米级旋四层序在塞向上叠加构成高级（五级、四级、三级）旋回层序时表现出周期性和规律性。这种不同级次的旋回层序的形成受不同动力成因引起的具不同周期和频率复合海平面变化的控制。米级旋回层序的识别与复合海平面变化的研究得出中寒武世鲕滩层序的形成经历了若干次周期性的淹没－间断－均衡堆积－加积进积事件，这为盆地充填史的恢复提供了新途径。     

Seismic hazard assessment in the Ionian Islands based on observed macroseismic intensities

Catalogues of actual observed intensities are constructed for three towns in the Ionian Islands. They are used for seismic hazard assessment and the results are compared with those obtained by standard approaches; that is, by statistics applied to the data computed from epicentral parameters. The results show that seismic hazard is better assessed using observed rather than computed data, but preparation of the local catalogue presents non-trivial difficulties.

水库诱发地震的地震动特征

利用新丰江、美国奥洛维尔和蒙蒂赛洛水库地震极近场地面运动资料，研究了水库诱发地震的地震动峰值加速度衰减。结果表明，水库地震的峰值加速度高，衰减快。利用国内水库地震资料研究了水库地震烈度。水库地震烈度与同级天然地震烈度相比，一般是烈度高，衰减慢。水库地震的地震动反应谱频率高，地震动持续时间短
