Establishment of Gondwana Early Paleozoic Reference Poles and Tests for Terrane Motion

9317673格鲁诺该奖项支持对横贯南极山脉中部下古生代岩石的古地磁研究。 目的是获取东南极寒武纪和奥陶-志留纪岩石（540 ~ 410 Ma）的古地磁极，建立东南极早古生代视极移轨迹。 该APWP将用于：1）限制东南极洲在冈瓦纳的位置，从而测试现有的冈瓦纳APWP中的环路的可能性，2）为测试跨南极山脉中的外来生物的可能性提供基线，3）评估东南极洲不同部分之间移动的可能性，冈瓦纳板块拼合与碎裂的构造模式检验。 ***

9317673 Grunow This award supports a paleomagnetic study of lower Paleozoic rocks in the central Transantarctic Mountains. The objective is to obtain paleomagnetic poles from Cambrian and Ordovician-Silurian rocks ( 540 to 410 Ma) to establish an early Paleozoic apparent polar wander path (APWP) for East Antarctica. This APWP will be used for 1) constraining the position East Antarctica in Gondwana and thereby testing the possibility of a loop in the existing APWP for Gondwana, 2) providing a baseline for testing the possibility of allochthonous terranes in the Transantarctic Mountains, 3) evaluating the possibility of movement between different parts of East Antarctica, and 4) testing tectonic models of the amalgamation and fragmentation of Gondwana. ***
