The Marcellus Formation, also classified as the Marcellus Subgroup of the Hamilton Group,
Marcellus Member of the Romney Formation, or simply the Marcellus Shale, is a mapped
bedrock unit in eastern North America. It is a sedimentary rock formed from marine
deposits. Named for a distinctive outcrop near the village of Marcellus, New York in an
1839 geological survey, it extends 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. Stratigraphically, the Marcellus is the lowest unit of the Devonian
age Hamilton Group, and is divided into several named sub-units. Although black shale is
the dominant lithology, it also contains lighter shales and interbedded limestone layers
due to sea level variation during its deposition almost 400 million years ago. The black
shale was deposited in relatively deep water devoid of oxygen, making it only sparsely
fossiliferous. Most fossils are contained in the limestones, and the fossil record in
these layers provides important paleontologal insights on faunal turnovers. The black
shales also contain iron ore, uranium and pyrite, and the fissile shales are easily
eroded, presenting civil and environmental engineering challenges.

Firefighters said a valve on a train car broke and released the propane mix into the air. "I woke up around 5 a.m. and I smelled gas. I didn't know where it was coming from," said resident Patricia Wagner. "My wife said she smelled almost like a gas smell in our

This story from the series isn't about Pennsylvania but instead focuses on Colorado, where oil and gas drilling is causing concerns about the rising levels of methane. A previous story in the NPR series focused on plans to study the health of people who live near Marcellus Shale activity.
