摘要
盆山体系演化,尤其是盆山耦合过程与成矿的研究已成为当代地质科学研究的热点之一.我国陆相沉积盆地砂岩型铀矿床（点）分布广泛,成因类型多样.但对矿床的成因分析研究似乎缺乏总体的认识和深化.由于可地浸砂岩型铀成矿明显受到盆山体系的形成演化机制制约,尤其是盆地基底形成之后的盆山演化起着关键的作用.作者结合新疆10多年来的找矿实践,试图通过对区域大地构造演化及其对盆地形成演化的分析,初步分析新疆可地浸砂岩型铀成矿作用与区域造山、造盆作用的关系.通过个别盆地砂岩型铀矿找矿实例分析,进一步探讨盆山耦合过程中可地浸砂岩型铀成矿规律,并提出今后工作意见.
The evolution of mountain-basin system, especially the study of association of mountain-basin coupling and mineralization, has become a hot topic in the present geoscience. There are lots of sandstone -type uranium deposits or occurrences with wide distribution and varied genetic types in terrestrial sedimentary basins in China, but a generalized and deepening knowledge of the genesis of the uranium deposit has not been obtained. The in-situ leachable sandstone-type uranium mineralization is strictly controlled by the mechanism of formation and evolution of mountain-basin system, especially the mountain-basin evolution postdating the formation of basin's basement. Based on experience of mineral explorations for the last 10 years or more, a preliminary analysis has been made of the relationship between in-situ leachable sandstone-type uranium mineralization and regional mountain-basin formation in Xinjiang. Through case analysis of individual sandstone-type uranium deposits, a further discussion is made of the metallogenic regularity of in-situ leachable sandstone-type uranium deposit during the course of mountain-basin coupling. Suggestions are also put forward for the future work.
