本文是从地球物理场出发揭示基底构造特征的一次尝试。研究结果表明,浙南变质基底的褶皱、变质作用带、火山—侵入岩带及成矿带的展布方向都是近东西向的;控制磁性火山—侵入岩带的北西向断裂具深断裂性质;近东西向的火山—侵入活动是控制内生成矿的主导因素,浙南的主要内生成矿带以其中的花岗岩岩基为核心形成完整的成矿域。
This article is an attempt to reveal the structural features of the basement from the geophysical field. The results show that the folding and metamorphic belt, volcanic-intrusive belt and metallogenic belt in the southern Zhejiang metamorphic basement are nearly EW-trending. The NW-trending faults controlled by the magnetic volcano-intrusive belt have deep-rupture . The volcano-intrusive activity in the near east-west direction is the dominant factor in controlling endogenic mineralization. The major endogenous mineralized belt in southern Zhejiang formed a complete metallogenic domain with granite basement as its core.
