小行星9725577 在过去的十年里,一个连贯的、全球性的寒武纪古地理学已经开始出现,尽管仍然存在许多问题。 该项目旨在解决其中之一--来自摩洛哥反阿特拉斯山脉(沿着西非克拉通北方边缘)的寒武纪岩石是否起源于该克拉通,或者直到早寒武世之后才成为冈瓦纳板块的一部分。 古磁极将被获得和校正,以测试寒武纪这些岩石和冈瓦纳大陆其余部分之间的他构性。 预计结果将大大澄清冈瓦纳超大陆最终组装的时间和几何形状。
英文摘要
9725577 Kirschvink A coherent, global paleogeography of Cambrian time has begun to emerge during the last decade, although numerous questions remain. This project is aimed at resolving one of these-whether the Cambrian rocks from the Anti-Atlas Mountains in Morocco, along the northern margin of the west African craton, originated on this craton or was not yet a part of the Gondwana assembly until after the early Cambrian. Paleomagnetic poles will be obtained and corrected in order to test for Cambrian allochtoneity between these rocks and the rest of Gondwana. Results are expected to considerably clarify the timing and geometry of the final assembly of the Gondwana supercontinent.
