摘要
云台山峰丛—峰林的成景岩石主要为白云岩和(含)灰质白云岩,灰岩仅在峰丛—峰林基坐部分见及。成景岩石结构主要为颗粒结构和晶粒结构,且颗粒结构(颗粒和填隙物)、晶粒结构(晶粒白云石和少量泥质、少量陆源碎屑)在空间上各自顺层偏集呈层分布。此外,白云岩孔隙发育,孔隙类型有孔洞和裂隙两种,区内构造运动改造了原来的孔隙,加宽、加深其横纵向展布,增强孔隙的连通性,使原来较细级孔隙相互贯通成较大一级孔隙网,在水的溶蚀及机械崩塌等地质作用下成景。
The genetic rocks of Yuntaishan peak cluster-peak forest mainly are dolomite and calcite dolomite, limestone can only be found in the foundation of peak cluster-peak forest. The structures of genetic rock mainly are particle and grain. The grain structure and particle structure distribute along the stratum unevenly on the space. Additionally, the pore of dolomite developed and has 2 kinds： pore space and fracture, the regional structural movement changed the original pore, widened and deepened its vertical and horizontal distribution, strengthened the pore connectivity, the former thin pores threaded together to be thick pores, then the landscape formed by water corrosion and mechanical collapse.
