| Abstract: | Upper Cretaceous (Campanian and Maestrichtian) marine strata of the Rosario Group in the San Diego area include the Point Loma Formation and overlying Cabrillo Formation. Thes units contain 6 facies associations which define a deep-sea fan deposited by westward-flowing sediment gravity flows that transported sediments derived chiefly from batholithic and pre-batholithic metamorphic rocks of the Peninsular Ranges. The sedimentary basin initially deepened abruptly. The fan then prograded westward into the basin, with a retrogradational phase recorded in the uppermost part of the sequence. The fan was deposited along the eastern edge of a forearc basin similar to that of the Great Valley sequence in northern California. The western part of the fan appears to have been truncated by late Cenozoic strike-slip faulting.-from Authors |
