9316183 Sherrell PI在与1908年通古斯事件和1783年拉基火山爆发有关的冰芯中发现了铱(Ir)异常。 在与Robert Rocchia(巴黎)的合作中,他们将把这些分析扩展到其他冰芯,目标如下:1)测试和验证结果,2)对冰芯样品进行系统研究,以澄清Ir的分配,3)调查背景Ir沉积的时间变化。 研究结果对地层记录中铱的影响与火山源的争论具有影响,也对火山活动和影响与气候变化的联系具有影响。
英文摘要
9316183 Sherrell PIs have found iridium (Ir) anomalies in ice cores associated with the 1908 Tunguska event and the 1783 Laki eruption. In collabooration with Robert Rocchia (Paris), they will extend these analyses to other ice cores with the following goals: 1) test and verify findings, 2) make systematic studies on ice core samples to clarify partitioning of Ir, and 3) investigate temporal variability of background Ir deposition. Results have implications for debate over impact vs. volcanic sources for iridium in the stratigraphic record, and also for linking volcanism and impacts to climatic changes.
