临汾凹陷晚更新世以来河流阶地堆积的构造响应

Construction Response of River Terraces from Late Pleistocene in Linfen Concavity

河流阶地是地表侵蚀与堆积过程中出现的最普通的地貌形态.但仔细分析,在不同地域、不同历史时段,因构造、地形起伏的程度和气候变迁的影响,沉积物变化很大.本文根据这一特点,研究了临汾凹陷中阶地堆积与构造运动的关系,初步确定了堆积物普遍反映的构造变化特征.

River terraces are the most common physiognomy form appearing in the course of terrstrial erosion and accumulation.It varies largely in different areas and historical periods because of the effects on the level of construction and climate.According to the feature,we study the relationship between accumulation terraces and construction movement,then defines the feature of construction changes responded by accumulations.
