Apparent polar wander paths (APWPs) synthesized from paleomagnetic poles provide the most direct data for reconstructing past paleogeography and plate motions times earlier than ca. 200 Ma. In this contribution, we describe a new method APWP synthesis that extends Euler pole analysis of Gordon et al. (1984, https://doi.org/10.1029/TC003i005p00499) by placing it within framework Bayesian inverse...

Change in sea levels, be they isostatic or eustatic, impact humans and the paleogeography inhabit. In this paper we examine at Iqaluktuuq, a section of Ekalluk River, Victoria Island, Nunavut, between Tahiryuaq (Ferguson Lake) Wellington Bay. The area’s rebound impacted River’s development use area by two essential subsistence resources, Arctic char (Salvelinus alpinus) caribou (Rangifer tarand...

Abstract The Sichuan Basin was a part of the Yangtze Carbonate Platform (YCP) during Cambrian–Ordovician, and marine carbonates were deposited in basin this interval. Although previous studies have evaluated paleogeography, paleoclimate paleoecology basin, they primarily focused on biological evolution basin; however, analysis paleogeography is lacking. This study integrated outcrop sedimentolo...

Ophiolites are the remnants of ancient oceanic crust and upper mantle that were tectonically emplaced into continental margins. They display the only evidence for magmatic, tectonic, and hydrothermal processes associated with seafl oor spreading prior to 170 Ma because no oceanic lithosphere older than this age is preserved in the modern oceans. The occurrence of sheeted dikes, side-byside tabu...
