The Permo-Carboniferous of North Victoria Land, Antarctica: continental despositional systems and paleo-environmental evolution of a high-latitude Gondwana basin

这里的研究集中在南极洲北维多利亚大陆晚石炭世至二叠纪沉积盆地的演化，该沉积盆地是冈瓦那横贯北极盆地体系的一部分。该盆地的沉积物可以作为档案，破译近极纬度地区晚古生代冰库向早中生代温室条件过渡过程中沉积和环境演化的主要控制参数。岩石地层学、生物地层学、沉积相构造学分析和沉积物物源分析相结合，将能够重建沉积动力学、盆地类型和演化以及物源区特征。沉积相分析、生物相分析、生物地层学和地球化学指标的结合将提供晚石炭世/早二叠世冰川消融期间及之后古环境演化的详细图景，有助于提高对高纬度生物群二叠系/三叠系界线周围全球变化的认识。

The study suggested here concentrates on the Late Carboniferous to Permian evolution of a sedimentary basin in North Victoria Land, Antarctica, which is part of the Transantarctic Basin System of Gondwana. The deposits of this basin can be used as archive to decipher the major controlling parameters on the depositional and environmental evolution during the transition from Late Paleozoic icehouse to Early Mesozoic greenhouse conditions at near-polar latitudes. The combination of lithostratigraphy, biostratigraphy, architectural analysis of sedimentary facies and sediment provenance analysis will enable the reconstruction of depositional dynamics, type and evolution of the basin, and the characterization of source areas. The integration of sedimentary facies analysis, biofacies analysis, biostratigraphy and geochemical proxies will provide a detailed picture of the paleoenvironmental evolution during and subsequent to the Late Carboniferous/Early Permian deglaciation, and will help to improve the understanding of global changes around the Permian/Triassic boundary in high-latitude biota.
