| 中文摘要: |
| 巴音戈壁盆地沙拉扎山南部已取得砂岩型铀矿勘查重大突破,发现了塔木素铀矿床,但是盆地大部分地区工作程度还很低,属于有待开发的“空白地段”。文章通过对沙拉扎山南缘构造、地层、沉积体系、后生蚀变等地质特征的分析,认为该区铀成矿的主要控制因素为控盆构造、扇三角洲沉积、层间氧化带的分布。铀成矿主要受构造反转控制,形成于层间氧化带氧化还原界面附近。 |
| 英文摘要: |
| In the south of Salazar Mountain, Bayin Gobi basin, a great breakthrough has been made in the exploration of sandstone-type uranium deposit, and Tabulin uranium deposit has been discovered, but most areas of the basin are still at a low level of work, which is a “blank area” to be developed. Author expects that the study of metallogenic model of Tabulin uranium deposit in the southern margin of Salazar mountain can play a guiding role in uranium exploration in other areas. Based on the analysis of the geological characteristics of the structure、 strata、sedimentary system and post-genetic alteration in the southern margin of Salazar mountain, the author finds that the main controlling factors for uranium mineralization in this area are basin controlling structure, fan delta deposition and interlayer oxidation zone distribution. Uranium mineralization is mainly controlled by tectonic inversion and formed near the REDOX interface of interlayer oxidation zone. The paper points the way for uranium exploration in Bayin Gobi basin “blank area”. |
