摘要
本文以浙西北前震旦纪岩石的地质研究为基础,运用板块构造学的原理和方法,划分了该区的主要岩石大地构造单元。根据本区晚元古代的岛弧火山岩和花岗岩类、变质混杂岩,可能的刚性基底,以及前陆磨拉石建造;结合区域地质资料,提出本区陆-弧-陆的晚元古代早期的碰撞造山带模式,并认为这是在本区发生区域性晋宁运动所致。
On the basis of a geological study of pre-Sinian rocks, the major petrotectonic units in northwestern Zhejiang province have been regionalized by applying the platetectonic principle and method. According to the coexisting Late Proterozoic arc volcanic rocks and granitoids, metamorphosed mélanges, possible rigid basement and foreland molasse in the area, coupled with regional geological data, an early Late Proterozoic continent-arc-continent collision orogen model is suggested. This model may be used to understand the 'Jinning movement' that took place in the area.
