中文摘要: 通过分析鄂尔多斯盆地东南缘建庄地区铀成矿背景、铀成矿条件、铀异常信息,认为该区域具有丰富的铀源和平缓西倾单斜构造、辫状河沉积体系,泥—砂—泥地层结构完整,补-径-排机制较完善,具备优越的砂岩型铀矿成矿地质条件。区内直罗组下段砂体放射性异常发育,呈带状展布,经钻探验证已发现工业铀矿体,说明该地区具有广阔的铀矿找矿远景。
Abstract:Through the analysis of uranium mineralization background, uranium mineralization conditions and uranium anomaly information in Jianzhuang area on the southeast edge of Ordos basin, it is considered that the region has a rich source of uranium and flat west-tilted unislope construction, braided river deposition system.The mud-sand-mud formation structure was complete. The complement-diameter-drain mechanism was perfect. It had superior geological conditions for sandstone-type uranium ore-forming.The lower segment of the Zhiluo formation in the area was abnormally developed and exhibited in a ribbon.Industrial uranium ore has been found after drilling verification.This work indicates that the region has a broad prospect of uranium prospecting.
