Gneiss\|distilled water interaction at room temperature was investigated with batch\|reactors to study water\|rock reaction and geochemical evolution of the aqueous phase with time. The ion concentrations in water were controlled not only by the dissolution of primary minerals, but also by the precipitation of secondary minerals. The decreasing fraction sizes of gneiss could favor dissolution and precipitation simultaneously. Ca\+\{2+\} and K\++ were the major cations, and HCO\+-\-3 was the major anion in water. All the ions except Ca\+\{2+\} increased in concentration with time. The Ca\+\{2+\} release from the rock to the aqueous phase was initially much faster than the release of K\++, Na\++ and Mg\+\{2+\}. But after about 5-24 hours, the Ca\+\{2+\} concentrations in water decreased very slowly with time and became relatively stable. During the experiment, the water varied from the Ca\|(K)\|HCO\-3\|type water to the K\|Ca\|HCO\-3\|type water, and then to the K\|(Ca,Na)\|HCO\-3\|type water. The water\|gneiss interaction was dominated by the dissolution of K\|feldspar in the solution. The remaining secondary minerals were mainly kaolinite, illite and K(Mg)\|mica.

The reaction path in the (Ba, Sr, Ca)SO-4 solid-solution aqueous-solution (SSAS) system was experimentally studied using a batch-reactor method. The effect of the impurities "fluorite" and "iron sulfides" admixed in a natural barite sample on the reaction path was followed by analyzing the aqueous solution continuously. The dissolution and precipitation of the impurity "fluorite" affected strongly the reaction path in the SSAS system, especially the Ca/Sr/Ba ratio in the aqueous solution. This influence became stronger with decreasing CaSO-4 in the solid solution. The dissolution and precipitation of fluorite could hinder the CaSO-4 component from dissolving into water, and reduce the release rate of SO{2-}-4 from the solid solution to the aqueous solution and the removing rate of Ba{2} from the aqueous solution. In the presence of fluorite and sulfides, the aqueous Ba{2} and Sr{2} concentrations were controlled by the dissolution-precipitation of the end-members BaSO-4 and SrSO-4, respectively; the aqueous F-, Ca{2} and SO{2-}-4 concentrations were controlled by the dissolution-precipitation of fluorite. The incongruent dissolution of the (Ba, Sr, Ca)SO-4 solid solution caused the solid phase to become progressively more enriched in the more insoluble component (BaSO-4), while the aqueous composition shifted towards the more soluble end-members (SrSO-4 and CaSO-4) as equilibrium was approached to.

蛇纹岩、异剥钙榴岩和蛇绿碳酸岩是蛇绿岩套中超基性单元特有的3类岩石组合,该套岩石组合的形成过程复杂,经历了从地幔岩浆结晶分异、洋脊变质作用改造和俯冲-仰冲构造过程,记录了从地幔岩浆侵位到造山带形成、演化的全程信息。蛇纹岩由方辉橄榄岩、二辉橄榄岩和纯橄岩通过水化和氧化过程而形成;异剥钙榴岩由含水石榴石、符山石、绿帘石族矿物、透辉石和绿泥石等含水和含钙的硅酸盐矿物组成,是由基性岩经历钙交代和水化作用而形成;蛇绿碳酸岩则由高度破碎变形的蛇纹岩角砾和碳酸岩基质(方解石、白云石或菱镁矿)共同组成,碳酸钙主要来自海水参与蛇纹岩化过程产生的富钙热液。阿尔卑斯西部的Zermatt-Saas蛇绿岩体中这3种岩石的组合研究表明:蛇纹岩化过程发生在大洋变质时期,超基性岩体在海水的作用下形成蛇纹岩。蛇纹岩化过程中释放出主要来自斜方辉石和单斜辉石的钙,与水共同作用交代超基性岩体中的基性岩脉,从而形成异剥钙榴岩。蛇绿碳酸岩形成于俯冲变质之前或俯冲变质的早期。这3类岩石一经形成,都经历了其后的叠加变质作用,进而表明Zermatt-Saas蛇绿岩经历了大洋变质、与俯冲、折返和抬升有关的高压变质和区域变质、绿片岩相变质和晚期热液变质作用的pT轨迹演化,代表着西阿尔卑斯从洋脊变质作用到俯?

不同类型的水的混合可能引起溶解和沉淀作用的发生,从而导致混合水具有全新的完全不同于混合前的性质,应用PHREEQC模拟了Clara矿区地下水、泉水、地表水及矿坑水在相对于二氧化碳气体封闭的或开放的体系中的混合作用。模拟计算的混合水与实际水样中的主要离子的含量基本相同,较大的差别仅存在于微量组分。随着在混合过程中水的化学组成的变化,水的类型也会发生相应变化。不同类型水的混合可以导致饱和系数的强烈变化,从而引起某些矿物的溶解或沉淀。富Ba的Na-Ca-Cl-HCO_3类型水与富SO_4^(2-)的Ca-Na-SO_4-Cl类型水的混合是克拉拉矿次生重晶石形成的最主要原因。

使用批反应器实验研究 2 1℃时花岗岩与蒸馏水的作用来探讨水 -岩作用以及液相随作用时间的地球化学演化。粒度为 1～ 2 mm,0 .5～ 1mm和 0 .2～ 0 .5 mm的花岗岩样品各 15 0 g和 75 0 ml纯水加入用聚丙烯做成的3个批反应器中进行反应试验。试验过程中用电动马达连续转动反应器。试验时间为 6 0 d。结果表明 ,液相主要是 Ca- (K) - HCO3型水或 K- (Ca) - HCO3型水。K+主要来自钾长石的溶解 ,Ca2 +主要与斜长石中钙长石组分的溶解有关。K+ 很容易从含 K+ 的原生矿物中被释放出来 ,同时 K+ 也容易从水中析出形成次生矿物。水中“Ca过剩”可以很好地用斜长石的不一致性溶解反应来解释 ,钙长石和钠长石悬殊的溶解度差异也是水中“Ca过剩”可能的原因之一。实验结果与用表面反应控制速率模式的解释及 Na+ 和 H+ 的表面竞争交换相一致。

The main aim of this paper is to obtain the exact and semi-analytical solutions of the nonlinear Klein-Fock-Gordon (KFG)equation which is a model of relativistic electrons arising in the laser thermonuclear fusion with beta derivative. For this purpose, both the modified extended tanh-function (mETF) method and the homotopy analysis method (HAM) are *** applying the mETF the chain rule for beta derivative and complex wave transform are used for obtaining the exact solution. The advantage of this procedure is that discretization or normalization is not required. By applying the mETF, the exact solutions are obtained. Also,by applying the HAM semi-analytical results for the considered equation are acquired. In HAM ? curve gives us a chance to find the suitable value of the ? for the convergence of the solution series. Also, comparative graphical representations are given to show the effectiveness, reliability of the methods. The results show that the m ETF and HAM are reliable and applicable tools for obtaining the solutions of non-linear fractional partial differential equations that involve beta derivative. This study can bring a new perspective for studies on fractional differential equations. On the other hand, it can be said that scientists can apply the considered methods for different mathematical models arising in physics, chemistry, engineering, social sciences and etc. which involves fractional differentiation. Briefly the results may cause a new insight who studies on relativistic electron modelling.
