| 摘 要： | 中一新元古代，全球发生了重大的Rodinia超大陆地质事件。近年研究表明，中国在华南板块发生的晋宁造山运动是Rodinia事件的重要组成部分。大量研究数据显示，康滇地轴前寒武纪地层中所形成的金属矿床大多集中在900～700Ma间。这些矿床的形成与大规模基性、酸性岩浆活动密切相关，与晋宁一澄江运动构造一热液作用密切相关，显示构造环境由挤压向拉伸发展，这正是全球Rodinia超大陆由汇聚转变为裂解的重要时期。本文从同位素地质年代学、沉积环境方面探讨该时期的成矿作用对Rodinia事件的响应，铀成矿作用与Rodinia事件的关系。

| Abstract: | A Major geological event--Rodinia breakup occurred in the Meso-Neoproterozoic period. The recent study shows that the Jinning orogeny in the south China plate was related to the Rodinia breakup. A great amount of geological data indicate that metallic deposits hosted by the Pre-Cambrian on the Kangdian axis were formed 900-700 Ma ago and associated with large-scale basic and acidic magmatism and closely related with tectonic and hydrothermal process during the Jinning-Chengjiang epoch. Tectonic setting wher... |
