Mesozoic deposits crop out in East Greenland mainly between lat. 70°25′ and 76°20′N. The sediments were deposited in fault-bounded basins having a north-northeast trend. The faulting began during the late Paleozoic, but block faulting persisted through the Mesozoic and into Tertiary (tensional faulting) time. In the Mesozoic, tectonic activity occurred particularly during the Late Jurassic. During much of the Mesozoic, the area formed the margin of the northern Atlantic sea of that time.

Following the discovery of Prudhoe Bay oil field in 1968, much attention was turned to the Arctic in the search for giant hydrocarbon accumulations. The Soviets had already proved giant reserves in their West Siberian Basin, and exploration was moving ahead quickly in the Canadian Arctic. Plans were drawn up for an AAPG Symposium on Arctic Geology and held in February 1971. Papers were selected from the Symposium for this publication and cover seven topical groupings: Regional Arctic Geology of Canada, Regional Arctic Geology of the Nordic Countries, Regional Arctic Geology of the USSR, Regional Arctic Geology of Alaska, Comparisons in the North Atlantic Borders, Evolution of the Arctic Ocean Basin, and Economics of Petroleum Exploration and Production in the Arctic.
