判定地下水二维水动力弥散参数的直线图解法

弥散参数的求得，是正确认识地下水污染运移及对其控制的前提。本文根据极值理论和非线性方程线性化手段，导出了浓度和时间变化的线性关系，得出了确定弥散参数的直线图解法。它可以弥补其它方法的不足。借用实际弥散试验资料对其进行了检验，表明所建数学模型与实际模型之间吻合良好，即所求得的参数结果可信。

线性度方法在前兆观测数据分析处理中的应用

利用空间线性度方法，对前兆场中不同台站，不同学科的前兆观测数据从总体形态上进行综合分析，得到关于描述前兆场的新的特征量ａ（空间线性度）本文给出了空间线性度的具体计算方法，并以华北地区为例，分析处理了区内１９７０～１９９４年部分地电阻率和地下水位观测资料，所得结果表明，新的前兆特征量ａ在中强地震之前一年左右时间内有异常显示。     

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.     

Spatial-temporal Frame,Evolution and Mineralization of the Northern Qilian Metallogenic Province

Four metallogenic epochs occurred in different tectonic environments during theevolution of the Northern Qilian metallogenic province through the geological time. The Mid-dle Proterozoic metallogenic epoch witnessed the tectonic environment of crustal breakupcaused by mantle diapirism, in which ultramafic-mafic rocks were intruded along beep faultbelts and the superlarge Jinchuan magmatic Cu-Ni sulphide deposit was formed. In theMiddle-Late Proterozoic metallogenic epoch the crust was further broken to form anintracontinental rift, in which the Chenjiamiao style massive Cu-Fe sulphide deposits hosted bybasic volcanic tuff were formed in the lower volcano-sedimentary sequence, while the largesedex type Jingtieshan style Fe-Cu deposits were formed within the upper abyssal carbon-richargillaceous sedimentary sequence. The Early Palaeozoic saw the aulacogen environment, with-in which the Baiyinchang style superlarge massive base and precious metal sulphide depositshosted by quartz keratophyric tuff were formed in the Middle-Late Cambrian rifted island arcand the massive Cu-Zn sulphide deposits and magmatic chromite deposits associated with theophiolite suite were formed in the Early-Middle Ordovician, and the Honggou style massiveCu-Fe sulphide deposits hosted by spilite were formed in the Late Ordovician back-arc basinenvironment. In the Late Palaeozoic-Meso-Cenozoic, the metallogenic province went into anintracontinental orogenic stage characterized by compressive tectonic environment, in whichthere occurred carbonate-quartz vein type and tectono-alteration gold deposits associated withductile-shear structures.
