Correlation and provenance of upper Mesozoic chert-rich conglomerate of California

Geochemistry of the Great Valley Group: an integrated provenance record

“…As a result, conglomerate clast compositions can be quite variable (Figure 3). San Joaquin conglomerate typically includes more granite and diorite clasts (up to 47%) than Sacramento Valley conglomerate, which is richer in sedimentary and metasedimentary clasts (Figure 3; data from Rose and Colburn (1963), Bertucci (1983), and Seiders (1983) (Bertucci 1983).…”

“…Platina petrofacies Rose and Colburn (1963), Bertucci (1983), andSeiders (1983) Cretaceous grains that are typical of the Sacramento Valley section and also occur in the Upper Cretaceous San Joaquin section. Within the Sacramento Valley, 22% of zircon grains in the Lower Cretaceous section and 8% in the Upper Cretaceous section are Precambrian.…”

Distribution and juxtaposition of Mesozoic lithotectonic elements in the basement of the Santa Maria Basin, California

“…Numbers indicate township and range. and others (1982), Seiders (1983), and Toyne (1987) were used to identify the various Mesozoic lithotectonic units of this study. The published detrital modes consistently show that composition varies with age and that the concept of petrofacies as applied to the Great Valley sequence of the Sacramento and San Joaquin Valleys of California by Ojakangas (1968Ojakangas ( ),'lngersoll (1978, and Dickinson and Rich (1972) also applies to the Great Valley sequence west of the Sur-Nacimiento fault.…”

Facies architecture and provenance of a boulder-conglomerate submarine channel system, Panoche Formation, Great Valley Group: A forearc basin response to middle Cretaceous tectonism in the California convergent margin

“…Deep-water conglomerates have the potential to capture local sources through large-caliber clasts (e.g., Seiders, 1983;Ingersoll, 1990;Doebbert et al, 2012) and may also include clasts that have traversed confined pathways across exposed shelves and coastal plains during relative sea-level lowstands. We completed five conglomerate clast counts evenly distributed throughout the SLR field area (Figs.…”
