Chadwick, G.H., 1923, Chemung stratigraphy in western New York: Geological Society of America Bulletin, v. 34, no. 1, p. 68-69.


Summary:

Pg. 69. Included in Chautauquan at top the lower part only of the Catskill, and at base certain beds (Dunkirk shale, Gowanda shale, Laona sandstone, etc.) that had previously been included in the Senecan and in Portage group of western New York. In 1924 (New York State Mus. Bull., no. 251, p. 149-157) Chadwick again employed his modified definitions of Senecan and of Portage group. His charts show that the beds he transferred to Chautauquan (and to Chemung) he correlates with Cayuta shale and Wellsburg sandstone members of Chemung of central New York. Age is Late Devonian.

Summary:

Pg. 54, 60-61, table (facing p. 62). Chautauquan series. Embraces strata from base of Chemung to base of Bradfordian series of former classifications. Chautauquan was "viewed by New York State geologists as marking close of Devonian and overlying Bradfordian was considered of Mississippian age. Name Bradfordian series is here abandoned, and term Conewango series is applied to Devonian part of the Bradfordian "series." Conewango series is a closing phase of Upper Devonian sedimentation in New York and Pennsylvania. Chautauquan series comprises Girard stage below and Chadakoin stage above.
