中文摘要：本文通过洞穴石笋沉积过程的野外观察和剖面研究分析了洞穴石笋形成过程中的溶蚀作用。依据溶蚀的原理,本文把溶蚀作用分为物理溶蚀、化学溶蚀和生物溶蚀三种类型。野外观测和石笋剖面研究表明溶蚀作用是一类普遍存在的现象。在野外,物理—化学溶蚀表现为石笋顶部的滴蚀坑穴,生物溶蚀形成披覆于石笋表面的风化壳。在剖面上,物理—化学溶蚀表现为沉积纹层的中断、沿生长轴的充填构造和孔洞,生物溶蚀则形成剖面上风化壳层。

外文摘要：Based on field survey and lab analysis,we emphasized the dissolution in the process of stalagmite depositing. According to mechanism of dissolution, dissolution can be sorted into three types: physical dissolution, chemical dissolution and biological dissolution. With the study of field observations and stalagmite longitudinal profiles from South China, it shows that dissolution is ubiquitous phenomena which runs through the speleothem forming process. In the field, physical dissolution and chemical dissolution lead to errosion pits on the top of stalagmites. Biological dissolution forms crusts of weathering that wrap around stalagmites. In the longitudinal profiles, physics—chemistry dissolution forms discontinued sedimentary lamina, calcium carbonate filling formation and tiny voids. Biological dissolution shapes weathering crust laminae.
