South China was located near the equator in the eastern Paleo-Tethys Ocean at this time, and this region developed massive chert deposits during the Permian as part of the PCE.When the Permian sea retreated southward, it left the Permian Basin area with a restricted outlet. This resulted in an inland sea where evaporation greatly exceeded fluid intake, and a great thickness of "evaporite" sediments was deposited; one of these was potash, a critical commodity during World War I, until then a product obtained from Germany.Sea News: This is the News-site for the company Sea on Markets Insider Indices Commodities Currencies StocksThe shift in carbon isotope values is a global phenomenon and is interpreted as resulting from carbonate sediment interaction with ¹²C-rich waters at the end-Permian sea-level fall.If gondolellids lived in deeper waters, the 2‰ change in δ 18 O would preferentially correspond to a change in the oxygen isotope composition of Permian sea water and …Conglomerates and sandstones from the Permian Rotliegend Group contain clasts of Caledonian origin that suggests a basement source area and a sediment ...The Delaware Basin is the western portion of the Permian Basin, separated from the more developed Midland Basin by the Central Basin Platform.
