Hydrocarbon (coal, oil) reservoirs are tucked among the fragments of sedimentary rocks and fossilized coral reefs that make up the basin’s rock layers, which are up to 8,000 meters thick. In this photograph of part of the basin captured by astronauts on the International Space Station on June 27, 2007, dark brown to tan folded ridges of these Paleozoic sedimentary layers extend across the image from top to bottom.
