Proposal for a workshop on understanding the formation of the Siberian Traps and its effects on climate and life

[00:53 . 90]西伯利亚洪水玄武岩是地球历史上最大的火山喷发之一，与地球上最大的灭绝——二叠纪末期——几乎同时发生。形成这个洪水玄武岩省的过程以及与灭绝的联系还不是很清楚。要了解这一地球历史上的关键事件，需要综合许多学科。更好地了解西伯利亚洪水玄武岩对于评估过去2.5亿年间洪水玄武岩爆发和灭绝之间有争议但持续的一致性，以及洪水玄武岩和大火成岩省可能的复杂原因至关重要。该奖项将支持一个研讨会，以调查大约2.51亿年前的西伯利亚洪水玄武岩及其对海洋、大气和气候的化学影响，以及对P/TR大灭绝的新多学科领域和实验室研究的可行性和兴趣。研讨会将涉及约20人，以最大限度地代表各个学科以及参与者之间的互动。讲习班的主要目标是：确定对西伯利亚洪水玄武岩多学科研究的兴趣程度；概述如何解决关键科学问题（形成过程、化学和气候影响以及对灭绝的可能影响）；评估此类工作的科学、后勤和协作可行性。研讨会将于2005年秋季在布朗大学举行。来自岩石学、地震学、地质年代学、大气化学、古气候学、构造地质学和古生物学等领域的与会者将出席会议。

0531990ElkinsThe Siberian flood basalts are among the largest volcanic eruptions in Earth history, and are approximately coincident with the Earth's largest extinction, at the end-Permian. The processes that created this flood basalt province and the connection with the extinction are not well understood. Gaining understanding of this critical event in Earth history will require the integration of many disciplines. A better understanding of the Siberian flood basalts is crucial for evaluating the controversial but persistent coincidence between flood basalt eruptions and extinctions in the last 250 million years, as well as the possibly complex causes of flood basalts and large igneous provinces.This award will support a workshop to investigate the feasibility of and interest within the community for a new multidisciplinary field and laboratory study of the ca. 251 million-year-old Siberian flood basalts and their effect on the chemistry of the oceans, atmospheres, and climate, and on the P/TR mass extinction. The workshop will involve about 20 people to maximize representation from various disciplines as well as interaction among participants. The key goals of the workshop are to:o Determine the level of interest in a multidisciplinary study of the Siberian flood basaltso Outline how the key scientific questions can be addressed (formation processes, chemical and climatic effects, and possible effects on extinctions)o Assess the scientific, logistical, and collaborative feasibility of such an undertaking. The workshop will be held at Brown University in the fall of 2005. Participants from the fields of petrology, seismology, geochronology, atmospheric chemistry, paleoclimatology, structural geology, and paleontology will attend.
