Observations sur le karst de Bardas Blancas-Malargüe (Andes de Mendoza, Argentine)
Mikkan, R. A.
Abstract:
The karst of Bardas Blancas, situated south of Mendoza province, deve-lops in Jurassic and Cretaceous limes-tones. The continental and semi-arid climate (300 mm/year) is characterized by temperate summers and cold winters. The periglacial processes are actives. The relief presents a semi-karstic morphology: structural landforms ("Schichttreppenkarst" with cuestas) and afew dolines, swallow-holes and pavements. The Los Brujas cave, about 1 000 m long, shows a labyrinthic network (3 siaged levels) with phreatic passages. The impor-tant gypsum speleothems (crusts, flowers) in the lower level and the calcite-opale speleothems indicate an hydrothermal speleogenesis (dissolution by sulfuric acid and gypsum deposit). The actual and active tectogenesis of this region (uphft, hydrothermalism, volcanism) plays an important part in the geomorphological evolution.
