丹霞地貌概念讨论

关于丹霞地貌概念上的不同意见,主要是：①岩性岩相上是较单一的“陆相碎屑岩”还是涵盖多种岩性岩相的“沉积岩”;②地貌上是“丹崖”,还是“赤壁丹崖”,或是“赤壁丹崖群”。根据目前已知的中外丹霞地貌的基本特征,初步认为,丹霞地貌是由砂岩砾岩为主的沉积岩经侵蚀作用所形成的赤壁丹崖群地貌。近10a来,一些丹霞地貌概念,基本上属于“中国丹霞地貌”的概念,不完全符合世界丹霞地貌的实际情况。

On the Conception of Danxia Landform

There are two mainly aspects that contribute to the different views on the conception of Danxia Landform: 1.according to lithology and lithofacies, the question is whether purer "continental clastic rock" or "sedimentary rock" covering varied lithology and lithofacies; 2. according to landform, the question is whether "red cliff" or "bare and red cliff", furthermore, "bare and red cliffs". Today, based on the basic feature on Danxia Landform known at home and abroad, it showed Danxia Landform is such a landform of bare and red cliffs which sedimentary mainly composed of sandstone and gravelstone suffered from an experience erosion. Over the last 10 years, some ideas of Danxia Landform belong basically to the idea of "Danxia Landform of China", which are fully inconsistent with the facts of Danxia Landform around the world.
