Question on the spreading of the South China Sea Basin

摘要

摘要: 从板块构造学、地球物理学和地球动力学等角度,结合南海中央海盆及其周边的地质、地球物理资料进行综合分析论证,对南海“扩张成因”模式提出质疑.认为南海“扩张成因说”不能成立,其中的几个核心问题是:(1)数学理论模型的边界参数选取存在多解性,其结果与地质地球物理资料不符或相去甚远;(2)无法解释海盆区地球物理探测和研究所表明的地壳结构及岩性特征,也无法解释海盆区的断裂分布和岩浆活动特征;(3)地球动力学诸方面难以支持南海“扩张成因说”成立;(4)南海海盆周边不存在与南海“扩张成因”相关的相互强烈作用的地球物理和地质构造特征;(5)南海海盆不具备大规模扩张的空间.南海“扩张成因说”已严重阻碍对南海和周边的地质与地球物理研究工作的深入和发展,应该放弃.

Abstract: The spreading model of the South China Sea is questioned on the basis of integrated analyses and interpretation of geological and geophysical evidences in the South China Sea Basin and its vicinity from the view of plate tectonics,geology,geophysics and geody namics.The spreading model of the South China Sea cannot be admitted because of these following key questions:(1) The boundary parameters of mathematical theoretical model cannot be selected uniquely,and their results are different or even away from geological and geophysical evidences;(2) their results can neither explain crust structure and rock characteristics,nor explain fault distribution and magma action characteristics,which are indicated by geophy sical surveys and studies;(3) it is difficult for geodynamical evidences to support the spreading model of the South China Sea;(4) around the South China Sea Basin there are no such geophysical and tectonic characteristics int ensified by the basin spreading;and(5) there is no space for the large-scale spreading of the South China Sea Basin.The spreading model of the South China Sea heavily obstructs the deepening and development of geolog ical and geophy sical research on the South China Sea and its vicinity,therefore it must be given over.
