绘制了显生宙板块构造、古环境和岩相古地理图。这些地图说明了环北极地区的地球动力学演变。通过这一系列的重建，清晰地描绘了从罗迪亚解体到盘古大陆合并和分裂的大陆形态、岩相、构造和气候的关系。岩相分布表现出与大陆组合和解体以及大陆稳定北移有关的气候变化。从区域上看，环北极边缘盆地相反映了不同的大地构造发育阶段。大陆的组合形成了前陆盆地。大陆的分裂，特别是盘古超大陆的分裂，形成了与裂谷和被动边缘发育有关的盆地。俯冲带与弧后盆地有关。脊推作用引起的反转在盆地演化中发挥了重要作用。(C) 2003 Elsevier Ltd.版权所有。
Paleogeographic maps were constructed to depict the Phanerozoic plate tectonic configuration, paleoenvironment and lithofacies. These maps illustrate the geodynamic evolution of the circum-Arctic region. The relationship of the continental configuration, lithofacies, tectonics and climate from the disassembly of Rodinia to the assembly and breakup of Pangea is clearly depicted on this series of reconstructions. The distribution of lithofacies shows climatic change associated with continental assembly and disassembly as well as with the steady northward drift of the continents.From a regional perspective the facies in basins along the circum-Arctic margin reflect various stages of geotectonic development. The assembly of continents contributed to the formation of foreland basins. The breakup of continents, especially of the Pangean supercontinent, generated basins related to rifling and passive margin development. The subduction zones are related to the back-arc basins. The inversion caused by ridge pushing played an important role in the basin evolution. (C) 2003 Elsevier Ltd. All rights reserved.
