| A Preliminary Analysis of Organic Mineralization of the Disperse Element Selenium |
| 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. |
