The Golfo San Jorge Basin (
Spanish : Cuenca del Golfo San Jorge ) is a
hydrocarbon -rich
sedimentary basin located in eastern
Patagonia ,
Argentina . The basin covers the entire
San Jorge Gulf and an inland area west of it, having one half located in
Santa Cruz Province and the other in
Chubut Province . The northern boundary of the basin is the
North Patagonian Massif while the
Deseado Massif forms the southern boundary of the basin. The basin has largely developed under condition of
extensional tectonics , including
rifting .
[1]
The basin is of paleontological significance as it hosts six out of 22 defining formations for the
SALMA classification , the geochronology for the
Cenozoic used in South America.
At the center of the basin accumulated sediments reach more than 8,000 metres (26,000 ft) of thickness. Oil was first discovered in 1907 and over the years it has become the second most productive hydrocarbon basin in Argentina after
Neuquén Basin .
