| 摘 要： | 在总结郴州—邵阳走滑型构造岩浆岩带基本特征和活动历史的基础上,对其形成机制和成矿作用进行了探讨．认为该走滑型构造岩浆岩带由隐伏的基底断裂带、侵入岩浆岩带和盖层中断续分布的北西向褶皱、冲断层组成,是板块会聚时两板块凸出部分相接触形成的应力集中带。它不仅是地幔长期隆起(尤其是晚古生代)地带,而且是一条重要的控岩控矿控制岩相的活动带。其中走滑型构造—岩浆岩环境下的锡、钨、铜、铅、锌、金矿床主要与燕山期壳源改造—重融型、壳幔源混熔型中酸性、酸性岩浆岩有关。

| Abstract: | On the basis of systemmatically summarizing the primary features and acitivity history,the authors discuss the forming process and minerailzation of Chenzhou-Shaoyang strike-slip tectonomagmatic belt and consider that it consists of basement faults,intrusions and some NW-striking folds and thrusts located in the cover beds.The location of the tectonomagmatic belt was not only a mantle-upwarping zone but also an important rock- and ore-controlling belt in the studying area.The tin,tungsten,copper,lead,zinc and silver deposits located in the belt were closely related to Yanshanian intermediate-acid and acid granitoid in the region. |
