Analyses of hydrocarbon gases and sulphate in sediments from the King George Basin, Antarctica, supplement to: Whiticar, Michael J; Suess, Erwin (1990): Hydrothermal hydrocarbon gases in the sediments of King George Basin, Bransfield Strait, Antarctica. Applied Geochemistry, 5(1-2), 135-147

Michael J Whiticar & Erwin Suess
Thermogenic hydrocarbons, formed by the thermal alteration of organic matter, are encountered in several piston core stations in the King George Basin, Anatarctica. These hemipelagic sediments are being deposited in an area of active hydrothermalism, associated with the back-arc spreading in the Bransfield Strait. The lateral extent of sediments infiltrated by the hydrothermally influenced interstitial fluids is characterized by basalt diapiric intrusions and is delineated by an acoustically turbid zone in the sediments of the...
