| 摘 要： | 通过对泰康地区的铀源条件、构造条件、含矿建造地质特征以及氧化-还原条件等方面进行研究，综合分析了泰康地区四方台组砂岩型铀矿的成矿条件，认为盆地西部和北部的富铀岩体为其提供丰富的铀源，四方台组具有成矿所必需的泥-砂-泥结构，良好的补-径-排水文体系以及良好的氧化-还原条件.四方台组底部砂体中获得铀工业孔和铀矿化孔，显示出泰康地区四方台组在砂岩型铀成矿勘探方面具有较好的前景，找矿类型为层间氧化带型.

| Abstract: | Through the study of uranium source condition,tectonic setting,geological characteristics of ore-bearing formation and oxidation-reduction condition in Taikang area,the paper analyzes the metallogenic conditions of sandstone uranium deposit in Sifangtai Formation.It is considered that the uranium-rich rocks in the west and north of Songliao Basin provide abundant uranium source.The Sifangtai Formation necessarily has a mud-sand-mud structure,a good recharge-runoff-discharge system and oxidation-reduction condition for mineralization.The uranium industrial holes and mineralized holes are obtained in the sand body at the bottom of Sifangtai Formation,indicating a good prospect in mineralization and exploration of sandstone uranium with the prospecting type of interlayer oxidation zone. |
