建议放宽丹霞地貌物质基础形成时限

The Suggestion Loosens the Timelimit of Danxia Lundform

丹霞地貌形成的物质基础是红色陆屑岩系,凡具有形成红色陆屑岩系的地理环境,都有形成丹霞地貌物质基础的可能.有了物质基础能否形成丹霞地貌还要看物质基础形成后的地理环境条件.建议把丹霞地貌物质基础形成的时限放宽,突出“红色、砂岩、砂砾岩”,限定“定平、身陡、麓缓”的地质特征即可.

The material foundation of the Danxia landforms formation is red land scraps rocks department. Any geography environment that has the formation red land scraps rocks department is all visible to become the basal possibility of the Danxia land forms material fundationj whether it can be Danxia landforms still needs to see the material foundation formation of geography environment condition. We suggest to loosen the Danxia landforms, out standing “red, sandstone, the gravel rock”, geology characteristic that limit “the crest is fiat, steep slope, slow foothill” is then.
