主要由层厚而产状平绶的晚白垩—早第三纪陆相红色砂砾岩,在差异凤化、侵蚀,溶蚀,重力崩塌等综合作用下,形成以色红,顶平、崖陡、麓缓为主要特征的城堡状、塔状、柱状、棒状、峰林状地貌,称为丹霞地貌,因广东仁化丹霞山而得名。山高一般不大,以海拔100—500米的低山丘陵岗阜地貌为主。如含钙质,亦易形成洞穴,但通常规模不及岩溶洞穴;如地表水系发育,常形成山重水复的碧山丹山风景地貌,因与岩溶地貌有相似之处,亦称假喀斯特地貌。江西省众多断陷盆地中,白垩—第三系红层十分发育,约占全省面积的10%,以赣中、赣南最为发育,不少凤景名胜区如龙虎山、圭峰、阁皂山,翠微
The late Cretaceous-Early Tertiary terrigenous red sandy conglomerate, which is mainly composed of stratum-thick and flat-shaped ribbons, forms the reddish, top-level and steep cliffs under the combined action of differential phoenixes, erosion, erosion and gravity collapse, Piedmont as the main features of the castle-like, tower-shaped, columnar, rod-shaped, forest-like topography, known as the Danxia landform, named after the Guangdong Renhua Danxiashan. Mountain high is generally not large, with 100-500 meters above sea level mainly hill Fu surface. Such as calcium, but also easy to form caves, but usually less than the scale of karst caves; such as the development of surface water, often forming mountain Bishan Danshan complex landscape, due to its similarities with the karst, also known as karst landform. Among the many fault-depressed basins in Jiangxi Province, the Cretaceous-Tertiary red beds are well developed, accounting for about 10% of the province’s area, with the most developed in Jiangxi and southern Jiangxi Province. Many scenic spots such as Longhushan, Guifeng, Soap Hill, Cuiwei
