中文摘要
9317318 Stock该奖项支持在东经170度和西经80度之间的西南太平洋进行海洋地球物理研究。 最近在西南太平洋进行的海洋地球物理考察和高分辨率测高重力场解密的地球观测卫星数据,使人们得以在破译坎贝尔高原/查塔姆隆起陆块与玛丽伯德陆缘之间裂谷作用的复杂历史方面取得重大进展。 一个修正的板块相互作用的历史解释了许多在磁场和重力场中看到的神秘特征,但仍有几个问题需要新的数据来解决。 建议的海洋地球物理调查将:(1)阐明在南极和澳大利亚板块与西南太平洋板块镶嵌之间不断演变的三重连接处的板块相互作用;(2)确定板块镶嵌体的边界和相互作用,这些板块镶嵌体适应了与新西兰外太平洋-菲尼克斯海脊俯冲有关的快速变化的板块几何形状,大陆和大洋岩石圈的断裂和热点活动;(3)绘制太平洋-南极海脊的发展和几个小板块组合成现代太平洋板块的地图。 这一调查将有助于阐明南极洲和新西兰板块相互作用的动力学和板块构造演化。 ***
英文摘要
9317318 Stock This award supports a marine geophysical study of the southwest Pacific between 170 degrees E and 80 degrees W longitude. Recent marine geophysical cruises in the southwest Pacific and a high-resolution altimetric gravity field declassified Geosat data have allowed significant progress to be made towards deciphering the complex history of the rifting between the Campbell Plateau/Chatham Rise landmass and the Marie Byrd Land margin. A revised history of plate interactions explains many enigmatic features seen in the magnetic and gravity fields yet several questions remain that require new data for resolution. The marine geophysical survey proposed will: (1) elucidate plate interactions at the evolving triple junction between the Antarctic and Australian plates and the mosaic of SW Pacific plates; (2) define the boundaries and interactions of the mosaic of plates that accommodated the rapidly changing plate geometry associated with subduction of the Pacific-Phoenix ridge outboard of New Zealand, the rifting of continental and oceanic lithosphere, and hotspot activity; and (3) map the development of Pacific-Antarctic Ridge and the assembly of the several small plates into the modern day Pacific plate. This survey will help to elucidate the dynamics of plate interactions and the plate tectonic evolution of Antarctica and New Zealand. ***
