摘要
在对东南沿海基底地质研究作了一简要的历史回顾和现状介绍之后,本文认为解决这一至今仍悬而未决的地质问题的关键所在是同位素年龄值的正确解释,基底岩系变形历史和热事件史的研兖以及现代造山作用理论的理解.新的地质事实使作者相信东南沿海地区是一个由不同大陆地块拼贴而成的复合体,不同地块的基底岩系在现代地表上的出露构成了“华夏古陆”,因而这一名词作为一个地质概念,它是僵化的,由此而来的论争也是没有意义的。最后本文就澄清本区基底构造问题的途径提出了一些设想。
The nature of the basement of southeast China has been studied for over sixty years. Yet it is still a subject deeply concerned over by geologists from home and abroad.Though a few recent progresses has been amde, divergent views still exist as to the nature and evolution pattern of the basement. The most important problems in the study of the basement in the region are the correct analysis of radiometric ages, the study of the history of deformation history in rocks and the understanding of the new concepts about moutain biulding process.Some new discoveries in the region make the author to believe that the studied area is a collage of several differant continental blocks, The geological concept of 'Cathysia' is only a reflection of the ossified mind because it is rather a geographic term, Several avenues of future research are suggested to tackle the exsisting problems.
