侏罗-白垩纪时,中国东部发生了强烈的地壳变动,强烈的褶皱和断裂,形成了一系列山脉及内陆盆地;堆积了一套特殊的沉积建造;大规模的岩浆喷出及侵入,带来了丰富的有用矿产,所有这些早已引起了人们的重视。自从翁文灏(1927)创立“燕山运动”一名以来,几十年间,对它的研究有很大的进展近年来,笔者有机会在若干中生代盆地进行一些观察,对中国东部的燕山运动取得一些肤浅的认识,仅此提出供讨论。 During the Jurassic-Cretaceous period, intense crustal movements, intense folds and faults occurred in the eastern part of China, forming a series of mountain ranges and inland basins. A special depositional deposition was built up. Large-scale magma eruption and intrusion, Brought a wealth of useful minerals, all of which have drawn people’s attention. Since the founding of the Yanshan Movement by Weng (1927), there has been considerable progress in its research over the past few decades. In recent years, I have had the opportunity to make some observations in a number of Mesozoic basins and to obtain some superficiality in the Yanshan movement in eastern China. Only this is proposed for discussion.
