(Sociedad Geológica de España, 2001)The northern edge of Los Pedroches granodioritic pluton is deformed by the Conquista fault, a right ductile shear zone with a normal component. Consecuently, the rocks of this sector show gradual texture-structural ... -
Caracterización petrológica y geoquímica de los granitos metaluminosos tardíos del dominio continental de la banda metamorfica de Aracena (Macizo Ibérico meridional)
Díaz Azpiroz, Manuel; Castro Dorado, Antonio
; Fernández Rodríguez, Carlos (Sociedad Geológica de España, 2001)
Several late leucogranite small plutons appear in the high grade zone of the continental domain (CD), in the Aracena metamorphic belt (AMB). These leucogranites cross-cut the structures due to the main tectono-metamorphic ... -
Caracterización y selección de morteros de restauración aplicados a areniscas del Eoceno de Gipuzkoa utilizadas en la construcción de edificios
(Sociedad Geológica de España, 2001)We have studied the response of three commercial mortars (A, B and C) and a fourth one (synthesized by Teusa) under different laboratory tests (stiffness, setting time, water absorption, water suction, water-vapor permeability, ... -
