It is typically found conformally overlying the Marcellus Formation, and underlying the Tully Limestone (where present). The Mahantango has been divided into four members: 1  Tully Limestone: a fossiliferous calcaerous shale. 2  The Tully is a conspicuous formation, which separates the Mahantango from the Hamilton Group.3  Sherman Ridge: Olive gray, fossiliferous, claystone and siltstone with interbedded fine sandstones coarsening upward.t is named for the North branch of the Mahantango Creek in Perry and Juniata counties in Pennsylvania. It is a member of the Hamilton Group, along with the underlying the Marcellus Formation Shale.
Shallow Keys Shallow keys are sometimes used when the shaft diameter approaches the maximum bushing or hub bore range. In order to accommodate the large shaft, the bore keyway depth is reduced. The power transmission capability of this arrangement is not reduced, but may not be as robust as a standard key and keyseat.hallow Keys Shallow keys are sometimes used when the shaft diameter approaches the maximum bushing or hub bore range.
