Описание
Морфология
The Cornión massif is made up almost exclusively of Carboniferous limestone arranged in ESE-WNW-trending thrust sheets, with local thicknesses exceeding 2,000 m. According to a geological section by Senior, beneath the floor of Thesaurus about 300 m of limestone of the Barcaliante Formation would remain before reaching the impermeable basement.
In the lower part, the P20, P14, P8, P30, P14 and P100 shafts follow one another; the base of the P100, at -490 m, opens into a large horizontal meander. The floor of the cavity, at -930 m, is an impenetrable fissure. In the phreatic gallery located towards -700/-750 m, fluvial sediments appear, and the reddish siliceous sediments of the Permian found inside the Pozo Vega Huerta indicate a post-Hercynian sedimentary cover and an older karst phase.
Гидрология
From -130 m, active water circulates through the cavity, which plunges in the large Pozo Badabum, located towards -400 m and not descended. A flood peak was observed at -250 m only about 30 minutes after a storm at the surface (Preziosi et al., 1997).
Другие сведения
The entrance is located on the western edge of the Vega Huerta depression, less than 100 m NW of the entrance of the M2 (Pozo de Cuetalbo, -986 m).
История
In 1995, the Spéléo Club de la Seine (Paris) and the Associazione Speleologica Italia Centrale (Umbria) joined forces to work in Vega Huerta. In 1996 the teams forced the narrowing at -5 m and advanced to -200 m. In 1998, -620 m was reached, where the watercourse was lost in a passage that was too low. In 2002, ASIC cavers found an ascending passage and a new shaft, stopping at -650 m for lack of rope. In 2003 the descent continued from -630 to -770 m without reaching the base of the shaft. In 2004 the base of the P230 was reached, at -850 m. In 2006 the floor was reached at -930 m, in an impenetrable fissure; the fossil gallery Fréatic Brothers was discovered, of which 300 m were explored, and a bivouac was installed at -620 m. In 2007 an additional 450 m of galleries towards -750 m were surveyed, the bivouac was moved to the gallery, and Marc Faverjon's survey was dated October 2007.
