摘　　要：广丰白垩纪盆地中沉积一套冲积扇相和湖相以红色为主的沉积岩系,其岩石类型为砾岩、砂砾岩、砂岩、粉砂岩、泥岩以及透镜状淡水灰岩。在盆地的西南部和东南部,受盆地边界断层和红层岩性制约,形成以复式单斜山、石寨、石峰、峰林、石柱、石崖、巷谷、一线天、造型石等丹霞地貌景观类型,地貌发育处于壮年期。本文主要阐述广丰盆地红层、构造发育、丹霞地貌景观特征及其相互关系。There is deposited a suite of mainly red sedimentary rock series of alluvial fan and lacustrine facies in the Guangfeng Cretaceous red basin, the rock types include conglomerate, sandstone-conglomerate, sandstone, sihstone, mudstone and lens-shaped fresh-water limestone. In the southwestern and southeastern parts of the basin, restricted by boundary faults of the basin and lithologic characters of red beds, composite monoclinal mountains, stone castles, stone peaks, peak forests, stone pillars, stone cliffs, tunnel valleys, narrow gorges, mouldling stones and other landscapes of the Danxia geomorphologic landscape type are developed in their geomorphologically mature phase. In this paper, the characters and relationships of the red beds, structural developments and Danxia geomorphologic landscapes in the Guangfeng basin are represented.
