- Abstract
Frasnian strata of New York are within the Genesee (in part), Sonyea, West Falls, and Java (in part) groups, consisting of strata that grade from terrestrial clastics in the east to offshore dark-colored shale and pelagic limestone in the west. These strata contain tephra beds, brachiopods, conodonts, goniatites, spores, and other flora and fauna that allow global correlation and recognition of zonal and stage boundaries. Five third-order cyclic packages are recognized by distinct black shale to gray shale groups that are recognized within corresponding strata of the Burket and Harrell shale formations in Pennsylvania, the Flynn Creek and Dowelltown members of the Chattanooga Shale Formation in the southern Appalachian Basin, the Blocher and Selmier members of the New Albany Shale Formation in the Illinois Basin, and the Squaw Bay Limestone Formation and Norwood and Paxton members of the Antrim Shale Formation in the Michigan Basin.
