松辽盆地Q区砂岩型铀矿床典型特征与铀成矿关系
Relation between typical characteristics of sandstone-type uranium deposits and uranium metallogenesis in Q area of Songliao Basin, China
摘要
Abstract
The uranium deposit in Q area of Songliao Basin is anatomized by means of core observation,identification of thin sections and well logging analysis.The uranium deposit belongs to a typical sandstone-type deposit in the interlayer oxidization zones.There are three typical characteristics in the uranium deposit in research area.Firstly,the uranium deposit always exists in a gray sand body which have favorable sand-mud-sand structure.Secondly,the thickness of an orebearing sand body is within a specific range.Thirdly,uranium commonly enriches in a sand body that contains some carbon or clay.The existence of several aquifuges can make the liquid rich in uranium flow in a certain range and the sand body with proper thickness and containing some carbon or clay not only offers a great lot of sorbent but also makes the uranium in liquid have enough time to be deoxidized and adsorbed.Therefore,the sand body has the typical characteristics mentioned above is a perfect place for the uranium deposit.The redox zone and sedimentary microfacies are two important controlling factors for the enrichment of uranium.关键词
