Basic Characters and Causation of Shuanghedong National Geological Park in Suiyang,Guizhou

106地质大队于1959～1960年曾对双河洞石膏矿进行过地质勘查。1986年～2006年4月,先后有中、法、日等国专家19次进双河洞考察,初步查明了该洞总长度为105.7km,是亚洲第二长洞,在世界上排名第16位。该洞不仅规模宏大,网络复杂,且有一定数量的次生淋滤型石膏矿分布,成为国内外罕见的独特洞穴景观。双河洞自2004年荣获国家地质公园称号以来,已引起国内外专家的广泛关注。该洞的形成,与该区域大范围内下寒武统清虚洞组上部至中寒武统平井组下部白云岩中,含大量硬石膏层有着密切的成因联系。

From 1959 to 1960, 106 geological party has done geologic exploration for the gypsum mine of Shuanghedong. From 1986 to April 2006, many geologists from China, France, Japan and other countries have explored Shuanghedong for 19 times. It＇ s ensured the length of the river is 105.7kin, is the second lon- gest fiver in Asia, and the 16th longest fiver in the world.

Since Suanghedong got the title of national geological park, it has caused abroad attention of the geologist at home and broad. The formation of this cave has relationship with the abundant hard gypsum strata in the dolomite from Qingxudong formation in early cambrian period to Pingjing formation in middle cambrian period.
