摘要
本文综合分析了中国东部的卫星影象特征,并根据地貌、地球物理场、地震活动及火山活动等资料,确定了中国东部存在几条大型的北西向线性构造带。这些北西向线性构造带主要活动期在新生代,并对新生代的火山活动、沉积盆地及现代地震活动起主要控制作用。根据其演化史和力学性质可分为两种类型:继承性的张剪型和新生的压剪型。它们的成因机制与区域岩石圈的应力状态是一致的。因而,中国东部北西向线性构造的形成演化是岩石圈深部地质作用过程的必然产物。
In this paper the author comprehensively analyses the features of the landsat imagery, the data of the geomorphology and hydrology,the gcophysic fields,the scismic activities and the Cenozoic volcaniactivity,and points out that there are several main NW trending structural zones in the east China.The NW trending linear structures,whose main active stages are in Cenozoic period, basically control the Cenozoic volcanic activities,the sedimetarty basins and the seismic acrivities,and can be classified into two types according to their development and stress nature.One is the inherited shear-tension type and the other is the neogenic shear-compression type, whose original mechanism is related closely to the lithospheric stress state in the east China.The formation and development of the NW trending structures are controlled by the lithospheric deep geologic process.
