大别山北麓嵩寮岩丹霞地貌景观的地学成因研究

Geological Origin of Danxia Landform in Songliaoyan at the Northern Foot of Dabie Mountain

大别山(六安)国家地质公园嵩寮岩园区是一处典型的丹霞地貌分布区。该区内分布的丹霞单面山、赤壁丹峰、丹霞洞穴以及洞穴内的微地貌景观等具有典型特征。本文在前期对该区丹霞地貌景观进行野外调查和研究的基础上,将该区的丹霞地貌景观进行系统梳理,并总结其丹霞地貌景观的主要特征,最后从地貌成因角度对该地区的丹霞地貌的丹霞单面山、赤壁丹峰、双蟾岩、双蟾寺洞、嵩寮泻乳、蜂窝状洞穴等景观的成因进行地学解释。研究认为,该区与其他地区的丹霞地貌发育过程一样受到区内地质构造背景、岩层物质组成、内外作用力等要素的影响。但由于该区的构造盆地边缘结构的构造特征、区内岩层含有大量碎屑物质以及本区沙砾岩的钙质胶结等特征,可能是嵩寮岩丹霞地貌发育丹霞单面山、大型洞穴以及红层岩溶现象的主要原因。本文研究为进一步提高嵩寮岩丹霞地貌的地学科普和旅游开发价值等奠定了基础。

Songliaoyan is a typical Danxia landform area in the Dabie Mountain（Lu＇an）National Geological Park.There are cuesta,red wall and peak,Danxia caves and micro landscape in cave in this area,they all have typical characteristics.Based on field investigation and study of the Danxia landscape in this area early,the main features of Danxia landscape had been summarized.From the perspective of geomorphy,the cause of formation of the Danxia landforms include cuestas,red wall and peak,double toad rock,double toad temple cave,Songliao spilled milk,honeycomb caves landscape and so on had been explained.Research shows that Songliaoyan and other area had the same development process which influenced Danxia landform by tectonic setting,rock composition,effects of internal and external forces and other factors.But because of this area lies the tectonic basin edge structure,the structural characteristics of strata which have a large number of detrital materials and the rock of the calcareous cementation characteristics may be the main causes that Danxia landforms had been developed.The study laid the foundation for the value of popular science and tourism development of Songliaoyan Danxia landform.
