Marcellus Formation - Wikipedia
WEBThe Marcellus Formation or the Marcellus Shale is a Middle Devonian age unit of sedimentary rock found in eastern North America. Named for a distinctive outcrop near the village of Marcellus, New York, in the United States, [3] it extends throughout much of the Appalachian Basin. [4] [5] [6]
