The Marcellus Formation, or simply the Marcellus Shale, is a mapped bedrock unit in eastern North America. It is a sedimentary rock formed from marine deposits that is named for a distinctive outcrop near the village of Marcellus, New York. In an 1839 geological survey, it was found to extend throughout much of the Appalachian Basin. The energy development community is drilling deep beneath the Allegheny Plateau to reach its largely untapped natural gas reserves located near the high-demand markets along the East Coast of the United States. Kave Consulting, LLC is interested in buying mineral rights in the Marcellus Shale and in any other region throughout the United States.
