Dokumentation von zwei Quarzithöhlen am Roraima Tepui (Brasilien, Guyana)
Abstract:
The Gran Sabana extends over the area between the Amazonas and Orinoco River in the northern part of South America. There about hundred table mountains (locally named Tepuis) are rising above the wet savannah plain. One of these, the Roraima Tepui, is situated at the triple border junction of the states of Brazil, Guyana and Venezuela. The plateau is built up of sandstones and quartzites of palaeoproterozoic age (c. 1.9 Billion years). Several caves which have mainly developed due to mechanical erosion of not or just partly lithified sandstone layers have been explored. The aim of a Brazilian Austrian expedition in November 2010 was to visit caves in the southern part of the Roraima Tepui and search for new caves in the less accessible northern part. The Cueva Ojos de Cristal (or Sistema Roraima Sur) was visited. With a mapped length of 16.1 km it is the biggest quartzite cave known in the world. Two caves were mapped, the Hotel Coati and the Lake Gladys Cave, which are the highest lying documented caves of Guyana and Brazil respectively. The Hotel Coati is situated in the north of the Tepui and is a cave often used as a bivouac. It is a shaft, acting as ponor, which is accessible through galleries aligned at rectangularly arranged fissures. North of that cave, in the Guyanese part, the single lake on the plateau, the Lake Gladys is situated at 2665 m a.s.l. There, the Lake Gladys Cave with a total length of 68 m is draining the lake. The entrance lies behind a boulder fall and water disappears into a sump. At the Roraima Tepui there are other not docu - mented objects so far, as the shaft ponor El Fosso (The Pit). Even though no major systems were found during this short expe - dition, the potential of finding further caves in the northern part seems still good.
