Geology of Pennsylvania

Pennsylvania is enriched with many scenic geologic features and a strong geologic heritage. Survey geologists and cooperators are actively researching and mapping the geology across Pennsylvania, and are also actively researching the subsurface of Pennsylvania. Efforts are being made to continually provide information on the Survey's investigations. Selected research geology abstracts and papers from conferences and publications also are posted here.
