摘要: 河流阶地的研究是探索新构造运动的有效方法之一。对滹沱河太行山山峡段进行了详细的阶地测量,结果表明,该河段发育有四级河流阶地,反映了第四纪以来的四次间歇性隆升运动。甲子湾断层使这些阶地错断变形,系舟山-太行山断块隆起沿该断层产生翘起运动。说明太行断块北部地区仍然继承着上新世时期的构造运动特点,目前的区域构造应力状态没有发生根本的变化。

Abstract: The investigation of river terraces is an effective way to explain the neotectonic movements. The data obtained by detailed survey of Hutuo River terraces in Taihang canyon section show that there are four terraces in this river section, reflecting four intermittent uplifted movements since Quaternary. These terraces were offset and deformed by Jiazhiwan fault, along which the uplifted Xizhou-Taihang fault block was tilted. It is suggested that the northern segment of Taihang fault block is still following the natures of Pliocene movements, and the present regional tectonic stress state does not show any essential changes.
