The outcrop of the upper Silurian Cobleskill and Akron members of the Rondout formation of New York State extends from Buffalo to E. Schoharie County and is continuous except where the units have been removed by pre-onondaga erosion. Strata included in the Cobleskill, Akron, and Chrysler members of the Rondout formation, underlying Williamsville member of the Bertie formation, and underlying Brayman Shale include several distinct Carbonate facies which have been identified by field characteristics, thin section petrography, insoluble residue analysis, and x-ray diffraction. Subfacies of the Cobleskill include subtidal biomicrites with stromatoporoid biostromes and intertidal fossiliferous micrites, whereas the Akron contains dolomitized analogs of these limestones. The overlying Chrysler is composed of supratidal, laminated, thinly bedded, finely crystalline dolostone. Careful lateral tracing of lithofacies, analysis of vertical lithofacies sequences, and study of key beds within the Cobleskill and Akron have resulted in recognition of the lateral equivalence of these 2 members. 32 references.
