Sequence Biostratigraphy of Pennsylvanian and Permian Carbonates from the Burbank Hills, Utah
The carbonate strata at the boundary of the Pennsylvanian and Permian systems in west-central Utah are characterized by deepwater to shallow-water cycles. The boundary of each cycle is marked by a marine flooding surface. We have collected samples from various fossil-bearing cycles in order to correlate the fauna with the same cycles found in the Midwestern U.S. and Russia. So far, the progression of fusilinids from fusulinellid to schwagerinid has allowed us to narrow down the time frame of the Pennsylvanian-Permian boundary. Conodonts belonging to the genera Neognathodus, Idiognathodus, Streptognathodus, Swadelina, and Rabegnathus have allowed us to date the cycles as being Moscovian through Artinskian in age. We have also found an unnamed species of Idiognathodus in the lowest cycles. The eventual goal of this project is to delineate the lateral extent of these cycles to the north and south, find the cycle where the Pennsylvanian-Permian boundary occurs, and assemble a faunal succession of conodonts, fusulinids, and other relevant fauna to correlate cycles here with cycles in the midcontinent.
