Thermal evolution of Monte Blanco dome: low-angle normal faulting during Gulf of California rifting and late Eocene denudation of the eastern Peninsular Ranges

Article Abstract:

Issues concerning the thermal history of Monte Blanco, a structural and topographic dome in the Sierra El Mayor of northeastern Baja California, Mexico, are considered. This dome gives very valuable insights into the histories of late Cenozoic rifting and earlier Cenozoic denudation of the Peninsular Ranges.

Active continental rifting in southern Baja California, Mexico: implications for plate motion partitioning and the transition to seafloor spreading in the Gulf of California

Article Abstract:

Research is presented concerning the three major earthquakes which have taken place in the Gulf of California between April 1969 and June 1995. The influence of faults distinct from oceanic spreading centers on seismic activity in the area is discussed.

Isostatic rebound due to tectonic denudation: a viscous flow model of a layered lithosphere

Article Abstract:

Effective viscosity indicates the strength of a layer. A model of continental crust and mantle viscosity in response to tectonic denudation is made. The Earth's upper 150 km is constructed as a strong upper crust, a weak lower crust, a strong lithospheric mantle, and a weak asthenospheric mantle. The model predicts surface topography, Moho deflection, and footwall uplift. Another hypothesis involves a viscous layer overlain by an elastic one that is consequently extended. Both models suggest that upper crustal strains differ from those of elastically controlled flexure.
