中川地区的铀迁移特征及铀矿找矿有利地段分析
Analysis on the characteristics of the uranium enrichment migration and the beneficial sites of uranium ore prospecting in Zhongchuan area
摘要
Abstract
In order to find out the relative enrichment of uranium in the Zhongchuan area and the advantageous sites of uranium mine prospecting under the action of geochemical,this paper mainly analysis the distribution of original uranium and activated uranium and the migration characteristics of uranium by using of airborne gamma spectrometric data, which has discussed the uranium content and endowment of the strata(terrane)by using the parameters such as the abnormal superposition and the enrichment coefficient,and com-paratively studied the uranium content of different rocks in zhongchuan area by using the parameters including the Ur,the uranium-tho-rium ratio and the uranium-thorium lining ratio.Finally,it classifies the strata and terrane into uranium-rich source concentration body, uranium-rich concentration body, uranium-poor source concentration body and uranium-poor concentration body, and uranium-rich source concentration body is the most favorable for mineralization. By comparing the uranium content of different rocks in zhongchuan area,it is believed that the uranium content of the Zhongchuan rock is better. The Zhongchuan rock is a uranium rock,and the rest are thorium rock;it points out that the main enrichment areas of activated uranium include the structure broken zone,ex-contact zone and the edge of the basin. The superimposed compounding area of uranium increment and activated uranium is the most favorable for miner-alization.关键词
