廣西發(fā)現(xiàn)中國(guó)第二個(gè)云朵石洞穴奇觀

A joint Sino-French cave exploration team has discovered a rare "cave cloud" in South China's Guangxi Zhuang autonomous region, according to the Institute of Karst Geology of China Geological Survey.

據(jù)中國(guó)地質(zhì)調(diào)查局巖溶地質(zhì)研究所消息，中法聯(lián)合洞穴科考探險(xiǎn)隊(duì)在廣西進(jìn)行探測(cè)，其間發(fā)現(xiàn)一處罕見的云朵石洞穴奇觀，這也是在中國(guó)發(fā)現(xiàn)的第二個(gè)云朵石洞穴奇觀。

The cave cloud covers an area of 300 square meters and is only the second such structure found in China. It is distributed in seven pools within a cave, with each pool having the shape of a pumpkin or loaf of bread, according to the team of experts.
本次科考探險(xiǎn)隊(duì)初步探明，云朵石分布于7處池水中，呈面包狀、南瓜狀，總面積達(dá)300平方米。

"The formation conditions of cave clouds are very harsh, and the surrounding rock of the cave is mostly dolomite, and karst caves formed by dolomite are not common,” said Zhang Yuanhai, a senior engineer with the institute.
該研究所高級(jí)工程師張遠(yuǎn)海表示:“云朵石的形成條件非?？量?，其洞穴圍巖多為白云巖，白云巖形成的溶洞并不是很常見。”
