Shale Coal Petroleum Gas Observations

On an Expansion Tectonic Earth prior to the late-Permian Period all continental crusts were united as a single all-encompassing supercontinental crust covering the entire ancient Earth. Remnant waters were confined to a network of continental seas coincident with sedimentary basins. In this context the shale, coal, petroleum, and gas resources, depositional environments, and climatic settings coincide, prior to post-Permian breakup of the Pangaean supercontinent to form the modern continents and opening to form the modern oceans.
