Three students funded by the grant, and myself, worked on the Eifelian-Givetian boundary project in the summer of 2010; two others were funded for part-time work in Fall 2009. Seven sections in New York State, two in Pennsylvania, and three in Maryland and West Virginia, that likely contain the stage boundary interval were measured, described, and collected. Additional work was done on materials collected last year and on a drill core from West Virginia. The localities visited and collected include:
Oatka Creek, NY – Stafford LimestoneHanson Honeoye Falls Quarry, NY – Onondaga Formation, Union Springs, Cherry Valley
Seneca Stone Quarry, NY - Onondaga Formation, Union Springs, Cherry Valley, East Berne, Chittenango
Flint Creek, NY - Union Springs, Cherry Valley, East Berne, Chittenango, Stafford
Chestnut Street at Cherry Valley, NY - Union Springs, Cherry Valley, East Berne
Stockbridge Falls on Oneida Creek, NY - Union Springs, Cherry Valley, East Berne
Conesus Creek at Ashantee, NY – Stafford
Licking Creek, Felton County, PA – Marcellus
Chillisquaque Creek, Washingtonville, PA – Union Springs, Cherry Valley
Mt. Hermon Church, Cumberland, MD - Marcellus
21st Bridge Road, MD – Onondaga, Marcellus
Keyser Water Treatment Plant, WV - Marcellus
Tentaculitids, conodonts, and magnetic susceptibility samples were collected from the Seneca Member of the Onondaga Limestone, Union Springs Formation, Cherry Valley, East Berne, and Chittenango members of the Oatka Creek Formation, and the Stafford Member of the Skaneateles Formation in New York State and Pennsylvania. At present it seems that there is a discernable change in the polygnathid conodont fauna across the Eif-Giv boundary which may have regional or global significance.
