RT Journal Article T1 Análisis de los tipos de intestabilidades del macizo rocoso de La Virgen de la Peña (Huelva, España) T1 Analysis of the instabilities types in the Rock Massif of Virgen de la Peña (Huelva, Spain) A1 Alonso Chaves, Francisco Manuel A1 García Navarro, Encarnación A1 Camacho Cerro, Manuel Alejandro A1 Mantero Romero, Elena María AB Geological map of Virgen de la Peña rock massif has established that there are three sets of geologicaldiscontinuities in the rock mass: a) stratification set strikes NW-SE and dips more 70º NE; b) faults setstrikes NE-SW and has gently dips and c) joints set strike NE-SW showing steeply dips. Cubical or tabulateblocks are formed by three intersecting discontinuity sets. The analysis of stability of rock massif illustratesthe mechanics of failure involve the block toppling and sliding.
