| 摘 要： | 庐山-彭山地区原是一个经受印支早期伸展机制下所形成的变质核。它在后期又经受了挤压和伸展的多期构造叠加,致成今日面貌。印支早期所形成的伸展拉覆断层为庐、彭及其相关地区的燕山期矿液活动提供了良好的导矿和储矿空间,对矿产的形成与分布起着重要制约。

| Abstract: | Lushan-Pengshan region was a metamorphic core formed by tensional regimes in the early Indosinian orogeny. In the later period, it underwent repeatedly tectonic superimposition of extrusion and extension, leading to the formation of the today’s landscape. The extensional covering fault formed in Early Indosinian orogeny provided favourable space for ore migration and storage during Yanshanian ore-fluid acti vines in Lushan-Pengshan and other relevant areas, thus playing a controlling role in ore deposit formation and distribution. |
