Jellico EKP 6 (Carboniferous to of the United States)

Where: Clay County, Kentucky (37.1° N, 83.7° W: paleocoordinates 10.6° S, 22.5° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Breathitt Formation, Bashkirian to Bashkirian (323.2 - 298.9 Ma)

• The Breathitt Formation, which contains the coal zone studied, reaches a maximum thickness of about 950 meters, and is composed of clay-shale, siltstone, subgreywacke, and several relatively thin calcium carbonate beds.

• group of beds-level stratigraphic resolution

Environment/lithology: deltaic; graded siltstone

• The Pennsylvanian rocks of eastern Kentucky form a terrigenous clastic wedge that thickens to the southeast. These sediments were derived from the Appalachian highlands to the east and southeast, and were deposited in a deltaic environment in a rapidly subsiding trough. Brackish-water and marine invertebrate fossils in shale and calcium carbonate deposits indicate the occurrence of several marine transgressions during the Pennsylvanian Period (Rice et al. 1979)

Size classes: macrofossils, microfossils

Collection methods: surface (in situ), chemical, mechanical,
