中文摘要：

在大地构造位置上，桂东北地区位于江南造山带与华南褶皱带的过渡部位，具有独特的构造地理位置。在精细测试一系列典型矿床及其有关的花岗岩年代学的基础上，本文根据矿床类型、成矿元素组合，把该地区矿床分为6个成矿系统：①与志留纪花岗岩有关W—Mo矿；②与二叠世花岗岩有关Pb—Zn矿床；③与晚三叠世花岗岩有关W—Mo和Sn—NbTa矿床；④与中一晚侏罗世花岗岩有关的W—Sn矿床；⑤与白垩世花岗岩有关的W—Sn矿床；⑥与花岗岩有关的铀矿。这些矿床的形成与不同时期构造一岩浆演化密切相关，主要形成于同碰撞挤压环境或者碰撞后伸展环境。

英文摘要：

Northeastern Guangxi is tectonically located in the transition zone between the Jiangnan orogenic belt and the South China fold belt, and has a unique tectonic position. Using detailed analysis of a series of typical deposits and chronological data of granite related, along with deposit types and ore-forming elements, this study divided the deposits in this area into six metallogenic systems. （1） W-Mo deposits related to the Silurian granite; （2） Pb-Zn deposits related to the late Triassic granite; （3） W-Mo deposits and Sn-Nb-Ta deposits associated with the Triassic granite; （4） W-Sn deposits related to the Middle-Late Jurassic granite~ （5） W-Sn deposits associated with the Cretaceous granite~ （6） Uranium deposit related to the granite. The formation of these deposits is closely related to tectonic-magmatic evolution in different periods and formed mainly at syn-collision compressional setting and/or post-collision extensional setting.
