中文摘要
摘要本项目将从南极洲詹姆斯罗斯和西摩群岛上白垩纪晚期至古新世晚期地层的角度,探讨地球上最近一次大规模灭绝的K/T界线。它的目标是完善全球相关的磁和化学地层学,以确定灭绝的原因。虽然K/T事件与陨石撞击有广泛的联系,但有一些证据表明它可能是由全球气候变化引起的。这一领域可能包含的证据表明,灭绝在高纬度南部之前,在更温和的地方,这将支持气候起源。这项工作的更广泛影响包括研究生教育和通过一本科普书传播成果。
英文摘要
Abstract This project would address the Earth's most recent mass extinction ever, the K/T boundary, from the perspective of upper Cretaceous to lower Paleocene strata on James Ross and Seymour Islands, Antarctica. Its goal is to refine the magneto and chemostratigraphy for global correlations to determine the extinction's cause. While the K/T event is widely associated with a meteorite impact, there is some evidence that it may have been caused by global climate change. This field area may contain evidence that extinction in the high southern latitudes preceded that in more temperate locales, which would support a climactic origin. The broader impacts of this work include graduate education and dissemination of results through a popular science book.
