黔北习水地区丹霞地貌成景地层粒度分析与沉积环境讨论

Analysis on Grain Size of Scenery Layer and Sedimentary Environment of Danxia Landform in Xishui area,Northern Guizhou

随着地质科普与旅游地学的需要,红层型丹霞地貌正吸引更多人们的关注。黔北习水地区发育有以赤壁丹崖为特色的丹霞地貌景观,成景地层为白垩系嘉定组砖红、鲜红色碎屑岩。本文通过分析该套成景地层粒度特征,并结合其沉积构造,认为黔北习水地区丹霞地貌成景地层白垩系嘉定组为陆相辫状河流沉积环境,为今后旅游开发与保护提供重要的线索,具有重要的研究意义。

With the needs of geological science popularization and tourism geology,red beds type Danxia landform are attracting more and more attention.The Danxia landform characterized by red cliff is developed in Xishui area of Northern Guizhou.The formation of the landscape is brick red and bright red clastic rocks of Jiading formation of Middle Cretaceous.Based on the analysis of the grain size characteristics of the landscape formation and other sedimentary structures,it’s thought that the Cretaceous Jiading formation of the landscape formation of Danxia Landform in Xishui area of Northern Guizhou is a continental petal river sedimentary environment,which provides important clues for future tourism development and protection and has important research significance.
