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.
Width of sample is 9 cm. It is a vein of quartz with pyrite cutting through quartzite. Width of sample is 11 cm. This small sample of Jotnian quartzite from Finland is either strongly cemented sandstone or weakly metamorphosed quartzite.It is old (1.4 Ga) and a part of crystalline basement. Hence, it is usually considered to be a metamorphic rock. Width of the sample is 4 cm.This wall in Western Ireland (Connemara) is built of local quartzite blocks.t is old (1.4 Ga) and a part of crystalline basement.
