摘要
中央亚洲活动带是世界上重要的铀成矿带之一,我国的天山-阴山-燕山以北地区正处于此带内。文章以成熟陆壳控矿理论和多岛海地质构造演化理论为基础,在系统分析该成矿带不同构造单元古生代岩石地球化学特征及其反映的大地构造属性的基础上,探讨了该带地壳成熟度及其对后期砂岩型铀矿成矿作用的影响,并建立了相应的砂岩型铀矿时空定位模式。
The central Asia mobile belt is one of the most important uranium metallogenic belts in the world, areas of China to the north of Tianshan- Yinshan- Yanshan is just located within this uranium metallogenie belts. Based on the ore - controlling theory of mature continental crust and archipelagic geologic - tectonic evolution, this paper systematically analyzed the petrographic and petrogeochemical characteristics of Paleozoie igneous rocks and the tectonic attributes of different tectonic units in the study region, and discussed the Paleozoic crustal maturity and its influence to subsequent sandstone type uranium metallogenesis, and the time - space localization model of sandstone type uranium deposits was set up.
