Abstract:

The geology of the Gulf of California region is discussed as it pertains to developing a hypothetical structural model presented to describe Gulf evolution. The Gulf of California supposedly evolved as fractured plates of crustal material moved northwestward and Pacific-ward by gravitational sliding, on extremely gentle slopes, from the regions of western Mexico uplifted by batholithic intrusions. The source of the uplift and westward tilting, and perhaps the formation of the intrusions, is ascribed to the development of the East Pacific Rise. This rise is the present expression of a subcrustal welt that reaches the North American continent near the south end of the Gulf of California, as demonstrated by the work of Menard and others.
