| 中文摘要:本文综述了分散元素硒的有机亲合性及其地球化学解释，并对Ｓｅ的有机成矿作用进行了阐述，认为硅质岩是Ｓｅ来源的标志，而Ｓｅ被固定则有赖于有机质的参与。以拉尔玛硒－金矿床和渔塘坝硒矿为例，说明Ｓｅ的２种不同的成矿方式———沉积型和改造型。文章最后给出了寻找独立硒矿床的一些可能的地质标志。 |

| A Preliminary Analysis of Organic Mineralization of the Disperse Element Selenium |
|
|
| Abstract:The paper summarizes the organic affinity of the disp erse element selenium and gives a geochemical explanation,in addition,the organi c mineralization of selenium is discussed.The author proposes that chert is an indication of the source of selenium,and the fixation of selenium depends on pa rticipation of organic matter.Taking the La'erma selenium-gold deposit and Yutan gba selenium deposit as examples,the author presents two defferent mechanisms o f mineralization sedimentary type and reworking type.At last some possible geo logical indications for looking for selenium deposits are given. |
