Hecates Tholus, Marte: Inestabilidad del Edificio Volcánico
Hecates Tholus is a volcano located at the Elysium volcanic province in the Martian lowlands (32ºN, 210ºW). In addition to several nested calderas, the volcano shows several geological and geomorphological features that ... -
La cristalinidad de la illita y las temperaturas de las últimas etapas de deformación en la zona de cizalla extensional de Santa María de La Alameda (Sistema Central, España)
Tsige, Meaza; Capote, Ramón; Martín González, Fidel (Sociedad Geológica de España, 2002)The illite crystallinity index of Kubler (1C) has been studied to establish the conditions of the last deformation stages in the Santa María de la Alameda shear zone. For this study, it has been used mainly the fine grained ... -
La geometría fractal de los bordes de grano del cuarzo como geotermómetro: Aplicación a la Zona de Cizalla Dúctil Extensional de Santa María de la Alameda (Sistema Central)
Martín González, Fidel; Capote, Ramón; Tsige, Meaza (Sociedad Geológica de España, 2001)Principles of fractal geometry have been applied to the description of quartz grain borders and to the assessment of deformation temperature in milonitic rocks at the Santa Maria de la Alameda Ductile Shear Zone (Central ... -
La Sierra de Cártama: Pliegue con actividad reciente en las Béticas Occidentales (Hoya de Málaga)
Capote, Ramón; Insua Arevalo, Juan M.; Martínez Díaz, J. J.; Martín González, Fidel; Tsige, Meaza (Sociedad Geológica de España, 2001)In this work is shown how an active fold (the Sierra de Cartama fault) is marked by the drainage pattern and topography, besides of structural data. The Sierra de Cartama fold is an asymmetric fold with double plunge and ... -
Primeros resultados de huellas de fisión en apatito en el sector Lugo-Ancares (Noroeste de la Península Ibérica)
Capote, Ramón; Barbero, Luis; Insua Arevalo, Juan M.; Martínez Díaz, J. J.; Martín González, Fidel (2006)The Northwest of the Iberian Peninsula is characterised by the absence of Mesozoic sedimentary deposits, the Cenozoic sediments being scarce. Due to that, the chronology of the geological events in the area is difficult ... -
Tectónica extensional en el Sistema Central: La Zona de Cizalla Dúctil de Santa María de la Alameda (Madrid)
Capote, Ramón; Martín González, Fidel; Tsige, Meaza (Sociedad Geológica de España, 1999)The Santa Maria de Alameda (Madrid) Ductile Shear Zone is a complex mylonitic belt trending east -West and dipping 30°-60° southward. The hanging wall block sinks towards the South-Southeast. Its kinematics is in relation ...
