中文摘要:石花(方解石花、文石花和石膏花)是一种常见的岩溶洞穴次生化学沉积物,广泛分布于洞道周壁,以及石钟乳、石笋、崩塌堆积体表面,其成因不同,形态千差万别。云南多乐原溶洞中若干高悬的次生化学沉积物表面的石花,通过实地考察,发现是一种异位石花。其成因是石柱形成过程中,由滴水和溅水的协同作用所形成,而后石柱底座的古河流堆积体遭到侵蚀搬运,石柱悬空而成新的石钟乳或类石钟乳,附着其底部的石花相对抬高因而显露出来。此类异位石花为云南首次发现,可以作为指示溶洞内微地貌演化的重要依据。

Study on the developmental characteristics and mechanism of ectopic stone flower at Duoleyuan karst caves in Yunnan
Abstract:Stone flowers (calcite flower, aragonite flower and gypsum flower) are a kind of common secondary chemical sediment in karst caves, which widely distribute on the wall of caves, stalactites, stalagmites and the surface of collapse accumulation bodies,and their shape is varied with different causes of formation.The stone flower on the surface of some high-hanging secondary chemical sediments at the Duoleyuan karst caves in Yunnan is found to be an ectopic stone flower. The cause of formation is that ectopic stone flower was formed by the synergistic action of dripping and splashing during the formation of stone pillars, then the ancient river deposits below the stone pillars were eroded and transported, some stone pillars were suspended to form new stalactites or stalactites-like sediment, hence,the stone flower attached to the bottom of stone pillars were relatively raised and exposed. The ectopic stone flower was firstly discovered in Yunnan,which could be used as an important basis for indicating the evolution of micro-geomorphology in karst caves.
