Paleomagnetism of the Dwyka Series

9725386奥普代克在晚古生代，南半球的大部分大陆都被合并成一个称为冈瓦纳的“超大陆”，随后与欧洲和亚洲碰撞形成盘古大陆，盘古大陆本身在中生代分裂。 在晚石炭世，冈瓦纳仍然是一个连贯的块体，因此，所有的古磁极从这个时代的岩石应该对齐，如果年龄和磁性数据是强大的，古地理的重建是隐蔽的。 最近在澳大利亚确定的晚石炭纪极点与30年前在非洲确定的相同年龄沉积物的极点不匹配。 该项目将重新研究这些岩石，以确定年龄和磁性数据是否有误，或者冈瓦纳板块重建是否有误。 预计结果将澄清和解决这些极点中令人困惑的不匹配，这将有助于更强大的冈瓦纳大陆重建。

9725386 Opdyke During the late Paleozoic most of the southern hemisphere continents were joined into a "supercontinent" called Gondwana , that subsequently collided with Europe and Asia to form Pangea, which itself dispursed during the Mesozoic. During the late Carboniferous, Gondwana was still a coherent block, therefore all paleomagnetic poles from rocks of this age should align if the age and magnetic data are robust and the reconstruction of the paleogeography is covert. Recently determined late Carboniferous poles in Australia do not match poles from the same aged sediments in Africa that were determined 30 years ago. This project will restudy these rocks to determine if the age and magnetism data re in error, or if the plate reconstructions of Gondwana are in error. Results are expected to clarify and resolve this perplexing mis-match in these poles, which will read to a more robust reconstruction of Gondwana.
