水泥—丙烯酸盐复合浆液的实验性研究

水泥-丙烯酸盐复合浆液是在丙烯酸盐浆液的基础上研制出来的一种复合浆液，它既保留了丙烯酸盐浆液流动性好，固结体弹性好的优点，又大幅度地提高了浆液的抗压强度和粘结强度，因此在注浆时可以带来良好的综合灌注效果，还对复合浆液的粘度和强度进行了试验性研究。     

矿区构造变形岩相形迹填图、矿化趋势度的实测及其地质找矿——以胶东玲珑金矿田阜山金矿区为例

以玲珑金矿田阜山金矿区为实测地区，研究了胶东构造岩浆岩浆活化区玲珑-焦家式金矿的矿源岩系，对2km^2内矿源岩的构造变形岩相形变进行1/2000填图。在此基础上，提出矿化趋势度（MTD）的概念并完成阜山金矿区矿化趋势度的分布图。矿化趋势度的概念及其填图研究方法对于探讨将成矿模型转化为找矿模型、逐步建立更具体量化的找矿预测实测方法有重要的参考价值和应用前景。

复杂地质构造波动方程数值模拟

利用全声波方程进行地震波场的数值模拟，虽然可以计算全声波波场值，但是也常常会出现层间多次波，给资料解释造成一定的困难。作者在本文中根据无反射声波方程，采用有限差分数值解法，实现了自激自收时间剖面的制作，避免了层间多次波的产生。本方法不但允许速度有纵向变化，而且允许速度有横向变化，这使得模拟复杂地质构造的地震响应成为可能。实际计算结果表明，该方法是一种行之有效的自激自收时间剖面的计算机数值模拟方法。

Anomalous Enrichment of Silver in Organic Matter of the Songxi Shale-hosted Ag-Sb Deposit in Northeastern Guangdong

The silver contents of organic matter in the host rocks of the Songxi shale-hosted Ag-Sb deposit of northeastern Guangdong, South China, have been directly determined using the electron microprobe technique. The silver contents in two types of organic matter, marine vitrinite and solid bitumen, vary in the range from 100×10-6to 350×10-6, which are from tens of times to thousands of times higher than those of the host rocks in the ore deposit. The average silver content of the organic matter is also several times higher than the pay grade of silver for commercial mining of the ore deposit. It is quite obvious that the organic matter of the host rocks in the ore district is characterized by an anomalous enrichment of silver. The results of this study indicate that the silver anomalies in the organic matter have been derived from both the host rocks and the silver-bearing fluids of the Songxi black shale ore source. In the course of sedimentation and later hydrothermal reworking, organic matter was able     

Hydrothermal Alteration Zoning and Kinetic Process of Mineral-Water Interactions

This study reports the kinetic experimental results of albite in water and in KCI solution at 22 MPa in the temperature range of 25 to 400℃. Kinetic experiments have been carried out in an open flow-through reaction system (packed bed reactor). Albite dissolution is always incongruent in water at most temperatures, but becomes congruent at 300℃ (close to the critical point 374℃). At temperatures from 25 to 300℃, the incongruent dissolution of albite is reflected by the fact that sodium and aluminum are easily dissolved into water; from 300 to 400℃ it is reflected by silicon being more easily dissolved in water than Al and Na. Maximum albite dissolution rates in the flow hydrothermal systems have been repeatedly observed at 300℃, independent of flow rates.The kinetic experiments of albite dissolution in a KCl aqueous solution (0.1 mol KCl) indicate that the dissolution rate of albite increases with increasing temperature. Maximum silicon release rates of albite have been observed at 400℃, while ma
