人造气液包裹体方法及其在研究热液性质中的应用

人造气液包裹体方法在研究热液的物理化学性质方面较传统方法简便、易行。它可用于研究热液的等容线、不混溶性质及矿物在热液中的溶解度。本文解释了人造气液包裹体的合成方法和人造气液包裹体方法的原理,分述了应用此方法研究热液所取得的最新成果。此法不仅能用于研究热液的性质,也能用于其它方面的研究,具有广阔的前景。     

地震水文地质学

地震水文地质学是地震流体地质学的重要组成部分,地震流体地质学是地震水文地质学的重要推广,因为与地震紧密相关的不只是地下水,还有地下气体、石油等其他地下流体。鉴于流体地质学这一术语还不够普及,姑且用地震水文地质学作为学科名称。 在地震发生的深度内,尤其是在地壳内,固体与流体并存,其间存在着力学和物理化学方面的相互作用和动态平衡。在固体地壳受力、变形、破裂过程中,通过岩、土、水、气间的能量传递、物质交换和信息变换,地下流体的某些物理参数和化学组分会有灵敏的反应。地壳深部信息还能比较迅速地通过地下流体传递到浅部来。     

Characteristics and Applications of Fluid Inclusions in the Eogene System of the Biyang Depression—I.A Fluid Inclusion Study

Presented in this paper are the rypes,salinities,homogenization temperatures and organic components of fluid inclusions formed at the four stages of diagenetic authigenesis in the Eogene of the Biyang Depression.The results of cooling experiments on fluid inclusions were used to determine the fluid system and composition of saline aqueous solution in each of the stages .The homogenization temperatures of saline aqueous solution inclusions and hydrocarbon organic inclu-sions have been corrected by two approaches ,and the trapping temperatures and pressures of fluid inclusions at each of the stages have been obtained.This strdy has shed light on the physicochemistry and evolution of diagenetic fluids.The diagentic fluid system is a system which was transformed from a chloride-bearing to a carbonate-bearing system along with the diagenic evolu-tion.The decrease of diagenetic temperature at Stage III of diagenetic authigenesis suggests that the depression would have experiences uplifting at that time.The fluorescent characteristics of fluid inclusions indicate the varieties of organic components in fluid inclusions both in time and in space.     

热液系统流体输运—化学反应耦合动力学综述

输运－反应模式通过边疆质量守恒议程进行描述，它表示为主要组分的Ｎ＋Ｍ个耦合的非线性偏微分方程。这些方程可能通过有限差分或有限元等数值方法进行求解。利用准静态近似法，涉及平流、分子扩散和水动力弥散作用的地球化学系统的演化在时间上通过一系列静止状态模拟出来。模拟实际地质系统的动力学实验对输运－反应耦合动力学的应用具有十分重要的影响。
