A sedimentological study of the Thacher Limestone Member of the Manlius Formation (Lower Devonian Helderberg Group) resulted in the recognition of two facies: mudstones and calcarenites. Mudstones can be dolomitic or non-dolomitic; they are typically laminated, exhibit mud- or prism-cracks, and fenestrae. Calcarenites comprise very coarse-grained intraclasts or skeletal fragments, to peloids.
