| 摘 要： | 表生地球化学研究十分广泛。表生地质地球化学的研究包括有表生地球化学过程中各种动力学模型的研究，微生物对各种元素地球化学循环的控制作用及机理研究，岩石风化过程中定量指标的研究与应用，稀土元素在表生作用过程中的地球化学行为及有机质在表生矿产特别是金属矿产成矿机制中的作用的研究。上述诸方面的研究近年来已取得了不少新的成果，对表生矿产的形成机制及合理地开发和利用作出了应有的贡献。

| Abstract: | The scope of the studies on supergenic geochemistry is very wide,in which geology-geo-chemistry involves all kinds of dynamic models showing supergenic geochemical process,Con-trolling effect and its mechanism of microorganism to the geochemical circulation of variouselements,quantitative index of rocks during weathering,geochemical behaviour of the rareearth elements in the supergenic geochemical process,and the effect of organic matter to themetallogenic mechanism of supergenic ore deposits,especial metallic ore deposits,In recentyears,the studies on the above aspects have achieved much new progress and have contribut-ed very much to metallogenic mechanism,reasonably exploitting and utilizing of supergenicore deposits. |
