Geology of northern Alaska: Examining the Arctic Alaska-Chukotka microplate
The tectonic evolution of the Arctic remains a subject of considerable uncertainty. The unknown Paleozoic and Mesozoic movements of a large block of continental crust, the Arctic Alaska-Chukotka microplate, contribute significantly to that uncertainty. Edited by Julie A. Dumoulin and Allison Till of the US Geological Survey, this eight-chapter volume addresses that uncertainty and demonstrates the power of modern research tools to penetrate the effects of orogenesis and to reconstruct pre-deformational tectonic and paleogeographic histories.
