二连盆地乌兰察布坳陷中东部地区氧化带分带地质特征及其元素地球化学特征
Oxidation Zone Zoning Geological Characteristics and Geochemical Characteristics of Elements in the Middle East Wulanchabu Depression of the Erlian Basin
摘要
Abstract
The Erlian Basin has a large amount of oil and gas and coal resources, and it is also a rich integrated mining area for sandstone type uranium deposits. The study area is located in the Middle East of the Wulanchabu depression. The oxidation zone zoning is obvious, It has excellent uranium metallogenic condition of the ancient river channel type. Uranium mineralization is located in the gray sandstone of the transition zone, no mineralization was found in the oxidation zone and the reduction zone. The content of trace elements Co, Ni, Zn, Mo, Pb and U in the transition zone is higher. And the content of Rb, Cs, Ba, Bi, Th, Nb, Ta, Hf is low, the δEu is negative anomaly. The elements that are positively related to uranium enrichment are Co, Ni, Zn, Mo, Pb, La, Ce, Nd and so on.关键词
