Beskrivelse

The intracratonic Thule Basin straddles northern Baffin Bay and has its largest part submerged. The most extensive onshore exposures are on the Greenland side. The basin is one of several Proterozoic depocentres on the northern rim of the North American craton with comparable development histories: thick sandstone and basalt units in lower levels, often with red beds, are succeeded by carbonate/shale-dominated sequences. Two of these basins are the Athabasca Basin of northern Saskatchewan and the Borden Basin of northern Baffin Island, both known for their economic mineralisation, U and Pb-Zn, respectively.
