.... The Erin Formation includes major cycles of lignite and porcellanite, clay, silt and cross-bedded sand. Porcellanites are considered to be clay and shale material that has been baked or fused by the combustion of lignite. The lignitic beds are rich in plant material and often contain petrified tree trunks...

... The Appalachian Basin has a well-established history of shale-gas development ( Figure 1 ). The discovery and commercial use of gas from Devonian shales in the early 1820s in Fredonia, New York, is generally recognized as the birthplace of the natural gas industry. This significantly predates...
