...JAMES W. HAGGART; PETER D. WARD Abstract The Upper Cretaceous (Coniacian–lower Campanian) Chico Formation of the northeastern Sacramento Valley, California, includes three newly defined members at the type locality: (1) cobble conglomerate of the basal Ponderosa Way Member, (2) coarse-grained...

The most commonly used stratigraphic classification is the so-called rock-stratigraphic classification...

... is an efficient way to define biofacies—that is, groups of samples based on similarities in taxonomic composition, relative abundances, and diversity ( Ludvigsen et al., 1986 )—and is the most effective means of communicating this information. Ordination is used to characterize gradient structure in the data set...

Most of the microfossils are calcareous and fragmentary; they are preponderantly members of the family Globigerinidae. 1 Read before Society...

These results are based on my personal observations in the field, on fossils in the laboratory, and on all published data. No comprehensive study of well data in the Coastal...

... of Cantalamessa et al. (2005) on the Punta Ballena Member of the Jama Formation, this Pleistocene mixed siliciclastic-carbonate record is the first fully published outcrop example from an equatorial-tropical setting. These two examples demonstrate that hiatal shell bed development is possible also in the tropics...

In its work on the preparation of this report, the committee profited by the efforts of previous committees assigned to this same subject and by the suggestions of various members (present and past) of the Commission.

It is impossible on a lithologic basis to divide the subsurface sediments as they occur in wells downdip from the outcrops into the same formations or members that are mapped in the outcrops. The writers believe that the only divisions that can be made are paleontological divisions...
