摘要
“燕山运动”是对中国大陆影响很大的一次地壳变动,北京地区的实际资料表明它是在快速侧向挤压应力作用下,以突发的断块活动为开端,并继之以拉张,导致基性岩浆喷溢,花岗岩侵入,以及一系列沉积盆地的形成。中国东部其他地区也经历了类似的历史,“燕山运动”从现象看是一次来自太平洋方向快速打击的结果,地槽造山理论和板块学说都难以给出解答,用燕山事件能更确切地描绘有关现象。本文在排除了其他可能性以后,提出燕山事件的外星事件成因的可能性,并认为诸如陆壳的缺失,侏罗纪宁静带的成因,环太平洋带的共性等,都可能与外星事件有关。
Yanshanian Movement is of great importance to most parts of the continent of China. The data collected in the Beijing area show that the movement began with an abrupt block-faulting activity under rapid lateral compressive stress, followed by lateral extension, eruption of basic magma and intrusion of granite. The formation of a series of inland sedimentary basins and the o-rigin of a number of minerals and fossil fuels is connected with this movement. The other regions of eastern China underwent similar history. From the manifestation of the Yanshanian movement , it seems to be a consequence of a rapid strike from the direction of the Pacific Ocean. The geosyncline orogenesis and the plate tectonic theories fail to give explanation. The Yanshan Event is a more accurate description of related phenomena. After the exclusion of other possibilities, the author has suggested the possibility of the extra - terrestrial event origin, and considers the origin of the Jurassic Quiet Zone, the missing of some continental crust and the generality of the Pacific Rim may seek answer in such events.
