| 摘 要： | 广泛分布于中国中新生代沉积盆地中的砂岩型铀矿床在容矿层位、矿床类型(成矿作用)和矿化年龄的空间分布上有着明显的差异和变化规律。所有上述变化都源自每个构造域中新生代构造演化的自身特点,服从于中国西、东部的中新生代构造分别受印度板块和太平洋板块对亚洲大陆的碰撞、俯冲作用的影响。分布于中国西部和东部的砂岩型铀矿床分别归属于新天山和西太平洋两大成矿体系。中构造域的中新生代盆地及其中产出的砂岩型铀矿床则同时受到印度和太平洋板块作用的影响,兼具两大成矿体系的特征。

| Abstract: | The sandstone-hosted uranium deposits widespread in China's Meso-Cenozoic sedimentary basins are obviously different from each other in ore-hosting horizon,deposit type(ore-forming process)and in the spatial distribution of mineralization ages.All the above changes are originated from the specific characteristics of the tectonic evolution of each tectonic domain where the deposits occur,obeying the affect resulting from the collision of Indian plate and the subduction of Pacific plate respectively.Basins an... |
