摘要:
在大量大型石笋纵剖面观测研究的基础上,提出洞穴石笋成因形态分类,首次确立石笋纹(壳)层组合构造分类方案;阐明叠锥、叠柱、叠锥柱复合和叠锥柱彼此间夹复合等构造类型及类型中的拱凸、拱凹、水平、平凹等纹层(组)层面构造亚类的组成特征;指出有关构造类型和亚类是成笋时段洞顶滴水、滴流水水量和流态动态特征与过程的踪迹,纹(壳)层及其构造也是洞穴内外气候环境及洞穴(道、厅)地质、水文条件等制约因素的综合反映。
Abstract:
We put forward the genesis and shape classification of cave stalagmite on the basis of the observation and study of lots of large stalagmite vertical profiles and firstly establish a classification scheme in terms of the combination structure of stalagmite lamina or lamella. It is expounded the structural types of cone in cone, cone and pillar, cone in cone and pillar compound, cone in cone and pillar intercalated with each other, and the constitution characteristics of the bedding plane subtypes: arch-convex, arch-concave, horizontal, horizontal concave and so on. It has been pointed that the structural types and its subtypes of stalagmite lamina are the behavior characteristics of ceiling drop water of cave, amount of dropping and flow water, and flow regime during forming stalagmite. The lamina or lamella and its structure of stalagmite are the comprehensive reflection of the climatic environment inside and outside cave ,and cave geological and hydrological conditions and so on.
