Stratigraphy
| Formation: | Sisquoc | Member: | Tinaquaic Sandstone | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: The Sisquoc Formation contains two principal lithologic facies: a fine-grained basin facies ( Todos Santos Claystone mbr) consisting chiefly of diatomaceous mudstone and a marginal sandstone facies ( Tinaquaic sandstone mbr). The basin facies of the Sisquoc Formation overlies the Monterey Formation without discordance. A maximum thickness of 5000 ft is estimated from the subsurface, although the maximum exposed thickness of the formation is 3000 ft. AGE: Revised to Messian-Zanclean consistent with EPICC stratigraphic revision. | |||||
