摘要
自上世纪三四十年代,前苏联创立了关于晚第三纪(2001年后称为新近纪)—第四纪地壳运动和地质构造的学说——新构造运动以后,已引起地质学者和地貌学者的广泛注意。新构造运动的结果,直接影响现代地貌的发育过程和形态特征,影响现代地壳的稳定性和活动性,对于以保护地质遗迹为宗旨的拟建地质公园的专家来说,尤其引为重视。以房县南部地区近期发现的古河床砾岩、野人洞古暗湖(河)沉积物及多层夷平面等地质信息,分析该地区新构造运动的始末,认为其新构造运动是在古老碳酸盐岩岩石条件和印支期近东西向构造、燕山期近南北向构造基础上发展变化的。
Since 1930s and 1940s, Late Tertiary( called Neogene after 2001 )- theory of crustal movement in quaternary and geological structure - Neotectonics, established by Former Soviet Union, have attracted extensive attention of the geologists and geomorphologists. As experts of geopark with the principle of protecting geological vestige, the results of Neotectonics should be paid more attention, because it not only affects the development process and morphological characteristics of modem geomorphology directly, but also influences the stability and activity of modem crust. The history of Neotectonics is analyzed based on the geological information of new found ancient riverbed conglomerate, ancient underground lake or river sediments of Yeren Cave and multi-layer in southern Fangxian County. And the authors believe that the developments and changes of Neotectonic movement is on the basis of old carbonate rock condition and nearly E-W structure in Indosinian period,nearly S-N structure in Yanshan period.
