Summary:

First used the Tuckerton Member of the Allentown Formation. Unit is lowest member of formation. Consists of gray dolomite to silty dolomite; usually thick bedded with interbedded limestone and particularly prominent cyclic algal and oolite beds near top; some sharpstone conglomerate; beds tend to be more calcareous and shaly toward base, and may be older than otherwise equivalent Conococheague Group. Underlies Muhlenberg Member.
