Spannagel Cave
The Spannagel Cave ((ドイツ語:Spannagelhöhle)) is a show cave near Hintertux, in the Zillertal Alps in the Austrian state of Tyrol. Currently about 10 kilometres of cave have been discovered; guided tours enable access to 500 metres of the cave. Its entrance lies below the Spannagelhaus (2531 m), a mountain hut formerly run by the Austrian Tourist Club (ÖTK). The cave and the hut are named after Dr. Rudolf Spannagel, who was the president of the ÖTK from 1902 to 1904.
== Formation ==
The overwhelming part of the Zillertal Alps consists of the crystalline primary rocks, plutons and metamorphite, that do not support the formation of caves. The only exceptions are pockets of rock capable of karstification such as limestone, dolomite, gypsum and other carbonates. These pockets are generally of quite low thickness, and only allow small caves to be formed. The creation of caves also requires water solubility. The Spannagel Cave has arisen in a large vein of Jurassic calcite marble of the Hochstegen Formation,〔(''Spannagel Cave, Austria'' ) at www.bookrags.com. Accessed on 20 Jul 2011.〕 a marble with over 90% total carbonate content, that runs through the slate mantle of the ''Western Tauern window''. The formation of this extensive cave as a result of geological corrosion (and mixing corrosion) is explained by the tectonics of the region.
