摘要
本文按 D·G·Howell 等人关于地体的定义,将华北板块与扬子板块之间划分为三个地体。初步研究认为,上述二板块的碰接,实质上是先行拼贴于该两大陆边缘的诸地体间的再拼贴。由此引发的一系列地质效应中,主要的构造效应有:体间滑动、层间滑动、热构造事件以及叠缩作用等。
According to the definition of terrane given by Howell et al.,three terranes can be dis-tinguished between the Yangtze and North China Plates.Preliminary study suggestes that the collision and connection of the Yangtze and North China Plates are.in fact,the re-col-lision and accretion of terranes that were already attached to the margins of these plates.This resulted in a series of geological effects,among which are the following:1.interterrane slip;2.interlayer slip;3.heating structural events;and 4.superimposed reduction
