我们已经重建了大陆,海洋和海洋大火成岩省(LIPs)自1000 Ma以来的古地理,以解码太平洋超级地幔柱的历史,使用最可靠的最近的数据与蛇绿岩带,地质年代学和古地磁数据从每个大陆的造山带的增生地质。根据重建结果,我们得出以下结论:(1)太平洋超地幔柱的形成时间为750 Ma,并使Rodinia超大陆解体,(2)非洲超地幔柱的形成时间为200 Ma,并使Pangea超大陆解体,(3)太平洋超地幔柱的活动具有幕式特征,其活动高峰期分别为580-600 Ma、280-230 Ma和150-75 Ma;(4)Rodinia形成时,来自特提斯-印度洋型洋的大部分大洋岩石圈沿着原Grenville造山带的古海沟俯冲,沿着沿Rodinia大陆岩石圈的V形、双面会聚边界俯冲。这些关系表明,大量的岩石圈俯冲下的太平洋型造山带引发了太平洋超级地幔柱的诞生后,200百万年在罗迪尼亚中心。
We have reconstructed the paleogeography of continents, oceans and oceanic large igneous provinces (LIPs) since 1000 Ma in order to decode the history of the Pacific Superplume, using the most reliable recent data for accretional geology from orogens associated with ophiolites and greenstone belts, and of geochronologic and paleomagnetic data from each continent. From our reconstructions we have arrived at the following conclusions:(1) the Pacific Superplume was born at 750 Ma and broke-up the supercontinent Rodinia;(2) the African Superplume was born at 200 Ma and broke-up Pangea;(3) the Pacific Superplume was active episodically with culminations at 580–600 Ma, 280–230 Ma and 150–75 Ma;(4) during the formation of Rodinia much oceanic lithosphere from the Tethyan-Indian type ocean was subducted along paleo-trenches of proto-Grenville orogens along a V-shaped, double-sided convergent boundary around the continental lithosphere of Rodinia. These relations suggest that the massive volumes of lithosphere subducted under the Pacific-type orogens triggered the birth of the Pacific Superplume after 200 my at the center of Rodinia.
