| 摘 要： | 以江西德兴斑岩铜矿床之细矿脉为研究对象,文章介绍了细矿脉剖面采集及研究的工作方法,着重讨论了自矿脉至围岩元素的空间展布特征。成矿元素Cu、Ag、S和控矿元素Fe、Rb、K都属确定性分布型。对照元素的扩散和渗滤理想模式,得到如下认识:在成矿成晕的地球化学过程中,成矿元素Cu、Ag、S以及Fe以扩散作用为主,控矿元素K和Rb以渗滤作用为主。

| Abstract: | In the article, the ore veinlet of the Dexing porphyry copper deposit has been chosen as an object of study, the working method for the ore veinlet profiles has been introduced. The author gave emphasis in discussing the characteristics of spatial distribution of some elements from ore veinlet to the wallrock, and concluded that the ore-forming elements (Cu, Ag, S) and the ore-controlling elements(Fe, Rb , K ) have respectively definite distribution pattern. On comparing theobserved results with the conceptual model of diffusion and infiltration, the following points of view are reached, the ore-forming elements ( Cu, Ag, S ) and the ore-controlling element ( Fe ) are dominantly diffusional in the geochemical processes of ore-formation and primary dispersion, whereas the ore-controlling elements ( K, Rb ) are dominantly infiltrational. |
