汉中盆地是秦岭和大巴山之间的一个断陷盆地,第四纪地层极为发育。本文主要结合野外调查介绍了汉中盆地第四纪地质地貌概况:地层及阶地情况和部分断错地貌等等。认为第四纪时期间歇性的构造运动导致盆地内一、二、三级阶地的形成;通过对勉县-洋县断裂、茶坝-林庵寺断裂断错地貌的研究,认为其于中更新世有过活动。 Hanzhong Basin is a faulted basin between Qinling and Daba Mountains. Quaternary strata are extremely developed. This paper mainly introduces the general survey of the Quaternary Geology and Geomorphology in Hanzhong Basin based on the field investigation: the stratigraphic and terraced landforms and partial faulty landforms. It is considered that the intermittent tectonic movement in the Quaternary period led to the formation of the first, second and third terraces in the basin. Based on the study of the fault landform in the Mianxian-Yangxian fault and the Tea Dam-Lin’an Temple fault, The world has activities.
