摘要该项目将从南极詹姆斯罗斯和西摩群岛上的上白垩世到下古新世地层的角度,讨论地球有史以来最新的一次大灭绝--K/T界线。它的目标是改进磁性和化学地层学,以便进行全球关联,以确定物种灭绝的原因。虽然K/T事件被广泛地与陨石撞击联系在一起,但有一些证据表明,它可能是由全球气候变化引起的。这一区域可能包含有证据表明,南部高纬度地区的物种灭绝先于较温和地区的物种灭绝,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科普书籍传播成果。
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.
