A paleomagnetic investigation of rocks from the Ohio Range and the Dry Valleys, Transantarctic Mountains, Antarctica

Kellogg, K. S.

Abstract:

Two well-deinfed virtual geomagnetic poles (VGPs) for East Antarctica were obtained from the Middle Jurassic Ferrar Dolerite, sampled from a thick sill on Mt Schofp in the Ohio Range, and from a horizontal sheet intruding Paleozoic granitic rocks at Mt Cerberus in the Dry Valleys. The VGP from the sill at Mt Schopf lies at lat. 58??.0S, long. 129??.0W (dm = 13??, dp = 12??), and the VGP from Mt Cerberus lies at lat. 57??.8S, long. 135??.7W (dm = 6??, dp = 6??). These data, together with 15 other acceptable pole positions reported in the literature, define a Middle Jurassic paleomagnetic pole at 52??.7S, 139??.6W (??95 = 4??.4). -from Author
