Tectonic Evolution of the Antarctic Sector of the Pacific Margin: Mesozoic and Paleozoic Development of Marie Byrd Land

西南极大陆构造演化及其与地球化学的关系 东南极洲是最基本的构造问题， 南极洲。 它与全球板块的相互作用有关， 南大洋古环流、古环境和 古生物地理学也是发展 大陆本身。 美国-英国联合西南极构造学 项目（1983年至1988年）已经揭示了相当多的构造 威德尔海地区的演变。 一个由三部分组成的美国 - 新西兰-联合王国玛丽伯德地学习方案 计划完成我们对地壳构造的理解 太平洋盆地南缘的演变。 它 将涉及实地和实验室调查， 阐明玛丽伯德地的结构和演变 地壳块体及其与西南极其他地区的关系 东南极克拉通、新西兰和 太平洋盆地。 这项研究涉及结构， 古地磁学和地质年代学研究 特别是前新生代的发展和玛丽伯德地。

The tectonic evolution of West Antarctica and its relationship to East Antarctica is the most fundamental tectonic problem of the Antarctic continent. It bears on global plate interaction, paleocirculation in the Southern Ocean, paleoenvironment, and paleobiogeography as well as being fundamental to the development of the continent itself. The joint United States-United Kingdom West Antarctic Tectonics Project (1983-88) has shed considerable light on the tectonic evolution of the Weddell Sea region. A tripartite United States -New Zealand-United Kingdom program of study in Marie Byrd Land is planned to complete our understanding of the tectonic evolution of the southern rim of the Pacific Ocean basin. It will involve field and laboratory investigations designed to elucidate the structure and evolution of the Marie Byrd Land crustal block and its relationship to other West Antarctic crustal block, the east Antarctic craton, New Zealand and the Pacific Ocean basin. This study involves structural, paleomagnetic and geochronologic investigations bearing particularly on the pre-Cenozoic development and Marie Byrd Land.
