生物礁岩分类方案

本文系统地提出了一个生物礁岩分类的新方案。生物礁岩首先根据次生组分的有无分为原生礁岩和次生礁岩。次生礁岩根据次生组分来源分为骨源次生礁岩和礁源次生礁岩。次生礁岩的二级分类根据次生组分的含量进行。骨源次生礁岩分为骨屑岩和含骨屑礁（灰）岩、倒骨央和含倒骨礁（灰）岩；礁源次生礁岩分为礁屑岩和含礁屑礁（灰）岩。骨屑岩根据次生组分的粒度分为巨骨砾（屑灰）岩、骨砾（屑灰）岩、细骨砾（屑灰）岩、骨砂（屑灰）岩；     

广东麒麟绿钙闪石巨晶的地球化学特征

本文对罕见的幔源绿钙闪石巨晶进行了综合的地球化学分析，主要元素，稀土微量元素和Ｓｒ，Ｎｄ同位素的特征表明；绿钙闪石巨晶是碱性玄武岩浆在地幔条件下的结晶产物；相对于寄主玄武岩，绿钙闪石巨晶均属捕虏晶，它们与共存的橄榄岩包体无成因联系，其形成可能与共存的黑色包体有关。     

Sequence Stratigraphy of the Permian--Triassia Boundary Section of Changxing, Zhejiang, Southern China

Three third-order sequences and about one hundred high-frequency cycles or Milankovitchcycles within the Late Permian Changxingian to Early Triassic Griesbachian are identified in theMeishan Section of Changxing, Zhejiang Province, southern China, the candidate stratotype sec-tion of the global Permo-Triassic boundary, based on a detailed study of the biological,ecological and high-resolution allochthonous cyclic events, microfacies and depositional systems.Furthermore, the stacking pattern of the depositional systems across various Changxingian andGriesbachian sedimentary facies of the Lower Yangtze and the sequence stratigraphic frameworkare outlined with the Meishan section as the principal section. In this paper the habitat types offossil biota are applied to semiquantitative palaeobathymetry and the study of relative sea levelchanges.

小应力变化触发大地震的研究

近年来,地震的孕育和发生是否可以用临界现象来模拟的问题引起地震学家的广泛关注.研究这个问题的方法之一是检验小应力变化是否确实触发大地震发生.这种检验必须具备两个条件:第一是作用在地震孕震断层上的小应力变化,第二是选择地震发生需要不同环境应力水平的地震.相同量级的小应力变化对于不同环境应力水平下发生地震的影响如果没有区别,则触发效应不存在;如果有明显差别,则触发效应存在.

Evaluation of soil liquefaction in the Chi-Chi, Taiwan earthquake using CPT

During the 1999 Chi-Chi, Taiwan earthquake, many sand boiling phenomena were observed in central Taiwan, which caused severe ground settlement and structure damages. According to the installed accelerograms, the peak ground surface horizontal accelerations in the liquefaction-affected areas range from 774.42 to 121.3 gal. The writers carried out an extensive investigation of soil liquefaction in this earthquake. In this paper, we present results of the CPT exploration and post-earthquake liquefaction analysis. Two hundred and seventy five (275) cone penetration test data were collected from the liquefaction-affected areas, and 46 liquefaction case histories and 88 non-liquefaction case histories were derived that can be used to evaluate the accuracy of existing liquefaction evaluation models. In addition, the strength of the liquefied soils after earthquake and the implication of its liquefaction potential in the future event are discussed.     

山西省主要河流流域面雨量预报业务流程

以T213、HLAFS模式、MM5中尺度模式输出的格点资料以及日本降水量格点资料为基础，将影响山西降水的天气动力模型归纳为诊断模型，从中引出多个能够全面反映降水模型特征的综合物理因子；根据各种数值模式输出的降水量预报性能和质量优劣特点，依据数值模式的形势场预报优于要素场预报的现实，构造在不同环流形势背景下，启动不同预报方程的面雨量预报业务流程，有效地遏止了在环流形势调整时预报输出不能快速响应的弱点，提高了点和面雨量预报的准确度。
