湖南郴州万华岩溶洞是湘南地区最著名的旅游胜地之一,是仍在发育中的大型地下河溶洞系统。万华岩溶洞中“石蛋生笋”奇观更是世界上首次发现,具有不可估量的岩溶科研、旅游观光、洞穴探险价值,但其成因一直不被公众所熟知。本文从地质运动的角度,系统地分析了“石蛋生笋”的成因,其地质形成过程最可能是:岩浆侵入-风化侵蚀-流水搬运-碳酸钙沉积。

Wanhuayan cave in Chenzhou city of Hunan province is one of the most famous tourist attractions in southern Hunan province.It is still a large developing underground river cave system.Wanhuayan karst cave is the first place in the world to discover the “stone eggs give birth to stalagmites”,which has inestimable value for karst scientific research,tourism and spelunking,but its cause has not been well known to the public.From the perspective of geology movements,this paper systematically analyzes the causes of the formation of “stone eggs give birth to stalagmites”.The geological formation process is most likely magma intrusion-weathering and erosion-water transportation-calcium carbonate deposition.
