0207407KellerThe International Continental Scientific Drilling Program (ICDP) is funding the drilling of a 2km hole in the Chicxulub impact crater on the Yucatan Peninsula in Mexico. NSF is funding US investigators to analyze core samples from the Chicxulub Scientific Drilling Project (CSDP). The Chicxulub crater is one of the world's largest impact craters and has been linked to the mass extnction event at the Cretaceous - Tertiary (K/T) boundary ~65 million years ago. As part of the CSDP Science Team, the Principal Investigators will carry out a collaborative and multidisciplinary effort that addresses three main topics: 1) the age of the Chicxulub impact, 2) evidence of multiple impacts, and 3) environmental and biotic consequences of the impact(s). The research falls into two categories. The first is an investigation of CSDP core samples by the PI to determine the age, biostratigraphy, faunal turnover, and paleoenvironment of deposition based on planktic and benthic foraminifera, and the correlation of this data with sections throughout Central America. The second is a collaborative research effort with other team members involving analyses of CSDP core samples for impact glass, sedimentology, geochemistry, and mineralogy. ***

0207407凯勒国际大陆科学钻探计划（ICDP）正在资助在墨西哥尤卡坦半岛的希克苏鲁布撞击坑钻探一个2公里长的洞。 NSF正在资助美国调查人员分析来自希克苏鲁布科学钻探项目（CSDP）的岩心样本。 希克苏鲁布陨石坑是世界上最大的撞击坑之一，与6500万年前白垩纪-第三纪（K/T）边界的大规模扩张事件有关。 作为CSDP科学团队的一部分，主要研究人员将开展合作和多学科的努力，解决三个主要问题：1）希克苏鲁布影响的年龄，2）多重影响的证据，以及3）影响的环境和生物后果。 这项研究分为两类福尔斯。 第一个是由PI对CSDP岩芯样品进行调查，以确定基于南极和底栖有孔虫的沉积的年龄、生物地层学、动物群更替和古环境，以及该数据与整个中美洲的剖面的相关性。 第二个是与其他团队成员的合作研究工作，涉及CSDP岩心样品的冲击玻璃，沉积学，地球化学和矿物学分析。 ***
