最近对美国西部Chinle组和Moenave组的古地磁研究表明,北美APW路径的J-1尖峰是尖锐的,其时代局限于晚Norian -早Sinemurian区间。这次更新将检查莫里森组的年轻岩石,以进一步证实尖头和APW路径的性质。研究结果对北美古地理及其构造地层体具有重要意义。
英文摘要
Recent Paleomagnetic studies of the Chinle and Moenave Formations of the Western United States have shown that J-1 cusp in the North American APW path is sharp and its age is confined to the late Norian to early Sinemurian interval. This renewal will examine younger rocks of the Morrison Formation to further substantiate the nature of the cusp and the APW path. Results would be of considerable importance to paleogeography of North America and its tectonostratigraphic terranes.
