The Upper Silurian Henryhouse Formation, of the Hunton Group (Upper Ordovician-Lower devonian), is a major hydrocarbon reservoir in the Anadarko basin. Detailed examination of Henryhouse cores were conducted at many localities in the basin, west of T10 W. Sedimentary structures, lithology, fossil content, and fabric relationships were used as criteria to recognize various depositional facies. Subtidal, intertidal, and supratidal facies can be distinguished readily, and their spatial relationships consistently indicate a shallowing-upward sequence. Previously unreported nodular anhydrite (replace and unreplaced) occurs at the top of the sequence, suggesting that hypersaline conditions developed in supratidal environments.
