Periodicities of 15 cyclic sections of the Cisco Group are tested through gamma and spectral analyses. The sections are composed of marine and nonmarine carbonate and siliciclastic rocks deposited on the Eastern Shelf, north-central Texas, in Late Pennsylvanian and Early Permian time. Gamma analysis generates facies-dependent thickness–time conversion factors (g’s) to construct g-corrected time series, which are more realistic than the uncorrected series obtained by proportional conversion… CONTINUE READING
