。丹霞地貌的构成物质地层属下白垩系河口群,岩性为紫红色厚层砂砾岩、砾岩最大高差达 300m 以上,无盖层。经水流切割、溶蚀、侵蚀和重力崩塌、风化剥蚀等综合作峰丛、方山、石柱、残丘等丹霞发育的各个阶段的单体地貌景观丰富而典型,对丰富我国丹丹霞峡谷:峡谷是指谷坡陡峻、深度大于宽度的山谷,通常发育在构造运动抬升和谷坡乎一致的又称为隘谷。谷地稍变宽,谷地两侧略有缓坡,倾角大于 60°的又称为嶂谷。公最窄处约 5m。 以炳灵丹霞峰丛(万笏朝天)最为典型。炳灵丹霞峰丛基座相连、峰顶分离,矗立于黄河岸丹霞崖壁:为直立陡壁,大多在河流岸边或丹霞峡谷两侧分布,坡度大于 60°,高度岩壁最为典型者如大寺沟佛翕状陡壁、直沟丹霞陡壁(百丈崖)、野核桃沟丹霞岩壁等。 平发育,四壁陡立,呈城堡状,长宽比小于 2:1。 裂构造线延伸。公园发育丹霞石墙多处,以野核桃沟石墙(佛掌崖)最为典型。 名并附会美丽传说。公园发育丹霞石柱多处,如大寺沟石柱(姊妹峰)、万佛沟丹霞石柱(文丹霞尖峰:丹霞尖峰四面发育陡坡,局部发育陡崖,山顶面不发育,整体呈锥状。公园丹霞洞穴:岩壁上广泛发育洞穴是公园丹霞石峰、石柱和崖壁的一个重要特征,成为岩度一般为 1-3 个/m2。部分洞穴穿透岩体,形成天窗、穿洞等奇特景观。广泛分布的洞穴还
geopark, with 24 representative geopoints (G32-G54 in table E.1.1-1). The strata of Danxia conglomerate interbedded sandstone, with near horizontal-gentle inclining occurrence. The 50-100 meters, and the maximum height difference is more than 300 meters. There is no caprock. Danxia canyon: Canyon refers to the valley with steep slopes and its depth is bigger than the width. It is usually developed in the area where tectonic movement uplifted and valley slopes are formed by hard rocks. When it cuts into the earth’s surface very deep, there are nearly vertical or very steep valley slopes, and the width of the valley is almost the same as that of the gulley. The valley is slightly wider, with gentle slopes on both sides of the valley, and the dip angle bigger than 60° is also called narrow gorge. Danxia canyon in the geopark are mainly composed of gulley and narrow gorge. A typical example is the Dasigou Gulley, with a slope height of about 150 meters, the valley width about 10-20 meters and the narrowest point about 5 meters. peak cluster of the geopark is distributed at Bingling gorge, Shaojiashan and other places.Among Bingling Danxia peak cluster is characterized connected bases, separated peaks, and standing on heavenward tablets. sides of Danxia canyon, with a slope of more than 60 ° and a height of more than 10 meters. caves are developed along the bedding due to weathering. The Danxia cliff is the most typical named Baizhang cliff), Yehetaogou Danxia cliff and so on. north of Zhigou, named Zhigou Fangshan. The castle-shaped Fangshan’s top is flat with nearly Danxia wall: Danxia wall develops in the shape of thin wall, its length is more than 2 times of are many Danxia walls in the geopark, the Yehetaogou wall (also named Buddha's palm cliff) is the Danxia pillars: it is a square or circular isolated stone column with a height bigger than the legends. There are many Danxia pillars developed in the geopark, such as Dasigou pillar (also Tibet) and so on. developed partly. The overall shape of Danxia peak is conical. Danxia peak is widely distributed in Danxia cave: caves are widely developed on the rock wall, which is an important feature of Most of the caves are honeycomb shaped, with a diameter of 0.3-1.0 meter, a depth of about 1.0 mass, forming skylights, holes, and other strange landscapes. The widely distributed caves also the geopark.
