摘要
陆良彩色沙林的形成,经历了三大阶段:产生彩色沙林的湖成三角洲相半成岩地层的沉积成岩;在地壳上升和湖浪、河流侵蚀作用下形成湖积-侵蚀台地;流水沿台地地层中的构造裂隙侵蚀形成交错分布的深陡冲沟,冲沟将台地地层割裂。最终才成生多姿多彩的彩色沙林。
The formation of Luliang colourful sand forest has experienced the sedimentary diagenesis of lacustrine delta facies paradiagenetic strata; the formation of lacustrine sedimentation - erosion stage under the function of the crust rising, erosion of lacustrine wave and river; the formation of deep and steep gully along the intersecting structural fissure by the water erosion, which cut up the strata of the stage.
