The chamber, discovered by a French expedition called Gebihe'89 in 1989, measures {{convert|852|m|ft}} in length, {{convert|191|m|ft}} in width, has an area of {{convert|154,500|m2|sqft}} and a volume of {{convert|10,780,000|m3|cuft}}. In 2013 members of a British led expedition measured the chamber using 3-D laser scanners.[1][3] Geology and formationFor more than 600 million years the area, in which the Gebihe cave system is located, was covered by sea and during this time it accumulated miles-thick layers of sediments, including limestone. The uplift of the area and then the erosion of the limestone layer created today's massive cavern system.[2] The system spreads out in limestones and dolomite of Carboniferous and Permian age. Old cave levels have been cut by erosion and follow the base level lowering caused by Tertiary uplift.[4] See also
