| 摘 要： | 白石岭—谷山岭地区位于海南岛北部的雷鸣盆地西部,是一个砂岩型铀矿产地。文章通过野外地质观察、粒度分析及前人研究资料的整理和分析,对该区白垩系岩相古地理特征进行了研究,初步确定了该区主要发育的沉积相类型及其特征。通过野外露头砾石颗粒的定向排列研究,对盆地沉降中心的迁移趋势及沉积物源进行了推测,初步认为该区物源主要来自盆地南部花岗岩和西部变质岩地区。

| Abstract: | The Baishiling-Gushanling area located in the west of Leiming basin is a standstone type uranium deposit area. Based on the field investigation, grain size analysis, collection and integrated analysis of previous data, the characteristics of lithofacies paleogeography of this area was studied, the main type and characteristics of sedimentary facies were preliminarily determined. By the study of directional arrangement of field outcrop gravel, the migration trend of sedimenary center and sedimenary source were inferred,it was inferred that the sedimenary source mainly comes from the granite body in south and the metamorphic rocks in the western basin. |
