黄河"几"字形河道的成因及其动力学分析
The Origin and Dynamic Analysis of the Ω-Shaped Channel of the Yellow River
摘要
Abstract
he formation and evolution of the Ω-shaped channel of the Yellow River depend on the boundary morphology and interactions of the tectonic belts around the Ordos block.The collision,subduction,compression,strike-slip and whirl effects of the peripheral tectonic belt on the block have made the Yinchuan Graben,Hetao Graben,Jin-Shaan Gorge and other tectonic landforms through the Yellow River.The highly developed fault zone,cataclastic rock zone and dense joint zone in graben and canyon have strictly controlled the extension and bend of the channel.In Neoid period,the extrusion of the Indian Plate in NE-trending and the Pacific Plate in NW-trending has compounded new ac-tivities of the peripheral major fault,which has controlled and constrained the Ω-shaped channel of the Yellow River.关键词
