Analysis of cyclic shallow-water carbonates: Cambrian Highland Peak Formation, eastern Nevada

Several methods of analysis were used to test the robustness of sea level signals recorded in Middle to lower Upper Cambrian shallow-water carbonate rocks in the southwestern United States and to refine stratigraphic correlation of this interval. Embedded Markov chain and cycle architectural analysis define the high-frequency accommodation signal, whereas cycle grouping pattern and facies proportions analysis reveals low-frequency sequence stratigraphic accommodation changes. Gamma analysis and Fischer plots were unsuccessful in deciphering the signature of high or low frequency signals; Six low-frequency accommodation events are present in the Middle to lower Upper Cambrian Highland Peak Formation. Each sequence is bounded by minimum accommodation zones that are correlative across the shallow-water carbonate platform and thus, record platform-wide relative sea level change. Two of these minimum accommodation zones record eustasy.
