Slave2Rae: The Lithospheric Structure of Ancient Cratons

0087699 Chave该项目的总体目标是更好地了解地幔如何参与太古代地幔的生长和稳定，这是形成大陆核的最古老的岩石。 深探测自然源电磁研究表明，它们可以通过定义岩石圈的基础和确定地幔内的结构特征，大大有助于这种理解。 在之前的NSF支持下，主要研究人员在加拿大西北部（奴隶省）加强了一项名为SNORCLE的多学科工作，该工作是加拿大Lithoprobe计划的一部分。 这是通过利用漂浮飞机部署在湖泊中的海洋大地电磁仪器来实现的。 由于预算限制，这项湖底活动的资金只包括对数据的初步分析;在本质上，是一项试点研究。 该奖项将允许PI进行彻底的分析和建模工作。*

0087699Chave The overall goal of the project is a better understanding of how the mantle participated in the growth and stabilization of Archean cratons, which are the oldest rocks that form the nuclei of the continents. Deep probing natural source electromagnitic studies have demonstrated that they can contribute substantially to this understanding by defining both the base of the lithosphere and by determining structural features within the mantle. Under previous NSF support, the principal investigators augmented a multidisciplinary effort called SNORCLE in northwest Canada (Slave province) that was part of the Canadian Lithoprobe program. This was accomplished by utilizing oceanic magnetotelluric instrumentation deployed in lakes from float airplanes. Due to budget restrictions the funding for this lake-bottom activity did not cover more than a preliminary analysis of the data; in essense, a pilot study. This award will allow the P.I.s to carry out a thorough analysis and modeling effort.****
