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.

本文研究了南极北维多利亚地晚石炭世-二叠纪沉积盆地的演化。该盆地的沉积可以作为档案，以破译的主要控制参数的沉积和环境演化的晚古生代冰窖过渡到早中生代温室条件在近极地纬度。岩石地层学、生物地层学、沉积相结构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代用指标的综合应用，将为研究晚石炭世/早二叠世冰消期及冰消期之后的古环境演化提供详细的信息，并将有助于提高对全球高纬度地区二叠纪/三叠纪界线生物群变化的认识。
