Análisis de anomalías gravimétricas y modelación cortical 2D de la región volcánica del Campo de Calatrava (Ciudad Real, España)
The volcanic region of Campo de Calatrava has been interpreted as a process of intraplate volcanism developed during Neogene. Two opposed geodynamic models have been proposed to explain the origin of this volcanism: a) a rifting process in an extensional context with localized crustal thinning; b) a...

| Sumario: | The volcanic region of Campo de Calatrava has been interpreted as a process of intraplate volcanism developed during Neogene. Two opposed geodynamic models have been proposed to explain the origin of this volcanism: a) a rifting process in an extensional context with localized crustal thinning; b) a flexural lithospheric process in a weak compressive setting with no crustal thinning. The analysis of the Bouguer gravity anomalies and 2D crustal gravity modeling contribute to discriminate between the geodynamic models proposed for the origin of volcanism. The gravity models are constrained based on previous deep seismic sounding profiles and the regional geological mapping. Gravity models reject a crustal thinning, and then strongly questioning, the aborted rifting model. However, gravity models support a flexural lithospheric process in weak compressive regime as the origin of Betic volcanism |
