Formation:Lagunitas
Stratigraphic resolution:formation
Stratigraphy comments: most in situ fossils are from the lower half of the section
Lithology and environment
Primary lithology:gray,green,yellow sandy,calcareous conglomerate
Secondary lithology:bioturbation,paleosol/pedogenic,ferruginous,green,red sandy claystone
Includes fossils?Y
Includes fossils?Y
Lithology description: "poorly sorted, angular to subangular gravel, moderately cemented by carbonates and low in clay content... Grey to yellowish-green interbedded sands and gravels"; "light green clays, with brown and red spotting and minor amounts of sand... soil development... Bioturbation... root casts"
Environment:fluvial-deltaic indet.
Geology comments: most in situ fossils are from alluvial sands and gravels; some are from lagoonal clays
former represent "short term turbulent sheet flow events in a coastal plain setting... [and] True river channel deposits"; latter represent "evanescent cutoff lagoons... no more than moderately saline"
