| 摘 要： | 气候-构造相互作用是目前固体地球和全球变化中最前沿的核心科学问题,地表侵蚀是气候-构造之间的桥梁纽带,地层沉积速率则是地表侵蚀强弱的直接响应.祁连山北缘-河西走廊在约4～2Ma期间沉积了一套粗粒相磨拉石-玉门砾岩,是研究气候-构造相互作用的一个理想产物,目前其气候或构造的主要成因存在争议.本文尝试阐述祁连山北缘-河西走...

| Abstract: | The climate-tectonics interaction is one of the frontiers of studies on global climate change and solid earth sciences in last decades. The key for deciphering this issue is the surface erosion,and the sedimentation rate is particular. The thick molasse,namely,the Yumen Conglomerate,deposited from 4Ma to 2Ma in the Hexi Corridor of NW China,is an ideal object for the investigation of climate-tectonics interaction. In this paper,we try to decipher the chief trigger for the formation of the conglomerate. Base... |
