摘要
本文通过卫星图像的分析研究,认为西藏高原内部存在巨大的地堑系,它表现为一系列受挽近活动断裂控制的断陷盆地和谷地。本文概述了地堑系展布特征,结合前人地质、地球物理资料,探讨了地堑系的内部结构及其形成机制。
In this paper. the author has studied the landsat image of the Xizang (Tibet) plateau, and has infered that there ex-
ists a great recent graben system. These grabens are actually fault-depressed basin and are generally controlled by active
fault. The paper gives a systematic account of the distribution of the grabens. Combined with geological and seismologcal
data, a further investigation is made for their interior structures and their generations.
