摘　　要：通过福建省永安市大湖乡鳞隐石林地区两个剖面中埋藏石芽周围红色堆积物的沉积学研究，对鳞隐石林成因加以探讨。堆积物的粒度、矿物、化学成分分析，以及石英砂表面的微结构，都证实了这些红色堆积物是没有经过搬运的石灰岩岩体的风化残积物，鳞隐石林是石灰岩在一个相当长时间的稳定环境里，在较单一的动力条件下，受风化和溶蚀作用而形成的埋藏石芽，再经剥蚀裸露后发展成为石林，但在古代河流流过的地方，地表河流的搬运和沉积，在埋藏石芽和石林的形成过程中起着重要的作用。This paper deals with the origin of the Linying stoneforest by the sedimentary study of the terra rossa around the buried karren in two sections of Carboniferous and Permian formations in the area of Linying stoneforest, Dahu township. Yongan Municipality, Fujian Province. The grainsize, mineral and chemical compositions of the terra rossa, and microtexture of the quartz sand surface demonstrated that the terra rossa was the weathered residual products of limestones. So the stoneforest in the studied area was developed from the limestones by weathering and dissolution, first as the buried karren, and then through denudation and revealing of the ground deposits to finally become the karst stoneforest consisting of rock kege, rock towers in different sizes and forms. All these must be formed under the conditions of a stable geographical environment and an unitary exogenic hydraulic action in the long period. Howerver, where the river flowed through at that time, river transportation and deposition strongly effected on the formation of the buried karren and stoneforest.
