Rincón, Marta ; Márquez González, Álvaro ; van Wyk de Vries, Benjamín ; Herrera, Raquel ; Granja Bruña, José Luis ; Llanes Estrada, Pilar | Sociedad Geológica de España | 2015La morfología de los volcanes refleja los episodios de deformación sufridos por el edificio, aunque procesos de deformación diferentes pueden provocar morfologías similares. La modelización análoga es una herramienta clave para comprender mejor [...]texto impreso
Benito, G. ; Mediavilla, F. ; Márquez González, Álvaro ; Martínez, J. ; Anguita, Francisco | Elsevier Science B.V., Amsterdam | 1997A detailed geomorphological study of Chasma Boreale, a widely known feature of Mars’ north polar cap, has been carried out for the first time, along with a quantitative paleohydro logical model. It is concluded that the chasma was eroded by a fl[...]texto impreso
Anguita, Francisco ; Verma, Surendra P. ; Márquez González, Álvaro ; Vasconcelos, Manuel ; López Ruiz-Labranderas, Iván ; Lurrieta, Alejandro | Elsevier Science Publishers | 2001One hundred and ninety-one circular or elliptical features have been located on Landsat imagery of the Trans-Mexican Volcanic Belt (TMVB). The origin of most of these features is unknown. Nine have been recognized as collapse calderas (clearly v[...]texto impreso
Rincón, Marta ; Márquez González, Álvaro ; Herrera, Raquel ; Alonso Torres, A. ; Granja Bruña, José Luis ; Wyk de Vries, Benjamin van | Nature Publishing Group | 2018-04-18Catastrophic volcanic eruptions triggered by landslide collapses can jet upwards or blast sideways. Magma intrusion is related to both landslide-triggered eruptive scenarios (lateral or vertical), but it is not clear how such different responses[...]texto impreso
Depth of faulting and ancien theat flows in the Kuiper region of Mercuryfrom lobate scarp topography
Egea González, Isabel ; Ruiz Pérez, Javier ; Fernández Rodríguez, Carlos ; Williams, Jean-Pierre ; Márquez González, Álvaro ; Lara López, Luisa M. | Elsevier B.V. | 2012Mercurian lobate scarp sare interpreted to be the surface expressions of thrust faults formed by planetary cooling and contraction, which deformed the crust downto the brittle–ductile transition (BDT) dep that the time of faulting.

Ignacio San José, Cristina de ; Castiñeiras García, Pedro ; Márquez González, Álvaro ; Oyarzun, Roberto ; Lillo Ramos, F. Javier ; López Ruiz-Labranderas, Iván | Taylor & Francis | 2003The rocks of the 1982 eruption of El Chichón volcano (Chiapas, Mexico) display a series of geochemical and mineralogical features that make them a special case within the NW-trending Chiapas volcanic belt. The rocks are transitional between norm[...]texto impreso
Márquez González, Álvaro ; Pablo Hernández, Miguel Ángel de ; Oyarzun, Roberto ; Viedma Molero, Cristóbal | Elsevier Science B.V., Amsterdam | 2005The discovery of gullies on Mars suggests liquid water activity near the surface of the planet in recent times. Since liquid water is unstable under the present-day P–T martian conditions, the formation mechanisms of the gullies, and the source [...]texto impreso
Egea González, Isabel ; Ruiz Pérez, Javier ; Fernández Rodríguez, Carlos ; Márquez González, Álvaro | Europlanet | 2010In this work we use a mechanical dislocation program to analyze the fault geometries and depths associated with a group of prominent lobate scarps in Mercury. We obtain depths of faulting of 30-40 km. This range overlaps with those previously ob[...]texto impreso
Oyarzun, Roberto ; Viedma Molero, Cristóbal ; Márquez González, Álvaro ; Lillo Ramos, F. Javier | Blackwell Publishing Ltd | 2003A mudflow-like deposit resting on the bottom of the East Gorgonum Crater (Mars; 37.4S, 168.0W) may provide new insight regarding the debate on the existence of water over the Martian surface. Because water in a mudflow is confined to a porous me[...]texto impreso
Coello Bravo, Juan Jesús ; Márquez González, Álvaro ; Herrera, Raquel ; Huertas Coronel, María José ; Ancochea Soto, Eumenio | Elsevier | 2020-09Catastrophic flank collapses are common on oceanic islands of volcanic origin and often recognizable from the resulting morphology as large U-shaped embayments. However, post-collapse volcanic activity can infill such features, thereby obscuring[...]texto impreso
Márquez González, Álvaro ; Fernández Caliani, J.C. ; Anguita, Francisco ; Farelo, Agustín-Felipe ; Anguita, Jorge ; Casa, Miguel Ángel de la | Elsevier Science B.V., Amsterdam | 2004Geological analysis of Mars imagery supports the hypothesis that the planet has been the site of recent (texto impreso
