Tectonic Implications of Paleomagnetic Results from Marie Byrd Land, West Antarctica

Many questions have not been satisfactorily answered regarding the geologic history and tectonic motions of the crustal blocks that make up West Antarctica. Most previous work in West Antarctica was concentrated in the Antarctic Peninsula, Thurston Island, and Ellsworth-Whitmore Mountains blocks. Th...

Description
Summary:Many questions have not been satisfactorily answered regarding the geologic history and tectonic motions of the crustal blocks that make up West Antarctica. Most previous work in West Antarctica was concentrated in the Antarctic Peninsula, Thurston Island, and Ellsworth-Whitmore Mountains blocks. The Marie Byrd Land crustal block is a key element in several important problems but its history was the most poorly known. This study is a reassessment of the motions of the west antarctic crustal blocks resulting from the Jurassic and Cretaceous breakup of Gondwanaland as implied by paleomagnetic results from Marie Byrd Land.
