AbstractThe Great Valley basin of California (USA) is an archetypal forearc basin, yet the timing, structural style, and location of basin development remain controversial. Eighteen of 20 detrital zircon samples (3711 new U-Pb ages) from basal strata of the Great Valley forearc basin contain Cretaceous grains, with nine samples yielding statistically robust Cretaceous maximum depositional ages (MDAs), two with MDAs that overlap the Jurassic-Cretaceous boundary, suggesting earliest Cretaceous deposition, and nine with Jurassic MDAs consistent with latest Jurassic deposition. In addition, the pre-Mesozoic age populations of our samples are consistent with central North America sources and do not require a southern provenance. We interpret that diachronous initiation of sedimentation reflects the growth of isolated depocenters, consistent with an extensional model for the early stages of forearc basin development.

Stratigraphic Range

Investigation of specimens of “Terebratella” ovula Anderson, 1938 from the upper Lower Albian Upper Chickabally Member of the Budden Canyon Formation, Great Valley Group, California has allowed the examination of the species' internal structures by serial sectioning. “Terebratella” ovula Anderson is now referred to the genus Dzirulina Noutsoubidze, 1945. The stratigraphic range of the genus is extended from the Hauterivian–Aptian to the Albian. The geographic range of Dzirulina is increased from central and western Europe, the Caucasus and Georgia of eastern Europe, and northern Zululand, Africa to now include northern California, North America. This represents an additional record of an Early Cretaceous brachiopod genus with a low-latitude, transatlantic distribution, most probably related to dispersal across the opening Central Atlantic Ocean.
