普定县境内中下三迭系碳酸盐岩地层广泛分布,岩溶十分发育。本文采用福克的结构分类对普定县三迭系碳酸盐岩进行分类,并根据碳酸盐岩的结构特点解释其沉积环境,以及根据该地区岩溶发育的特点和不同岩溶层位地下水的化学特征,阐明岩溶的发育与碳酸盐岩的化学成分,尤其与岩石的结构和构造有着密切关系。该地区三迭系碳酸盐岩体中的一系列较太型峰林、峰丛、溶洞及地下河等的发育均与生物异化颗粒亮晶结构、生物异化颗粒结构及异化颗粒生物泥晶结构等类型的碳酸盐岩有关;溶蚀孔隙、裂缝孔隙和白云石化孔隙等岩石构造。亦促进岩溶的发育。
The middle and lower Triassic carbonate rocks in Puding County are widely distributed and have developed karst. In this paper, we use Fokker’s structural classification to classify the Triassic carbonate rocks in Puding County and explain the sedimentary environment according to the structural characteristics of the carbonate rocks. According to the characteristics of the karst development in this area and the groundwater of different karst layers Chemical characteristics, elucidation of karst development and the chemical composition of carbonate rocks, especially with the rock structure and structure are closely related. In the Triassic carbonate rocks in this area, the development of a series of relatively over-peaked peaks, peaks, karst caves and underground rivers are related to the structure of bio-alienated particles, the structure of bio-alienated particles and the structure of alienated particles Other types of carbonate rocks are related to; lithic structures such as dissolved pores, fractured pores and dolomitized pores. Karst development is also promoted.
