SGER: Investigation of COMIS for Paleomagnetic and Rock-Magnetic Research

RenneEAR-0236925这一小额勘探研究补助金(SGER)项目的目标是为硅酸盐(COMI)中结晶取向的磁铁矿包裹体(COMI)提供岩石-磁性和分析透射电子显微镜数据，以探索COMI的起源条件，以及在这些条件下它们记录磁场的保真度。研究计划包括分析不同样本中的一些COMI，以评估所获得的结果是否足够可靠，以将其用作古地磁指标。如果这一SGER成功，为COMIS开发的技术将被用于各种古地磁应用，包括测量地磁古地磁强度和古地磁数据的构造应用。这一结果也将有助于评估洋壳和其他行星上磁异常的稳定磁化是由于COMIS的可能性。

RenneEAR-0236925The goal of this Small Grant for Exploratory Research (SGER) project is to provide rock-magnetic and analytical transmission electron microscope data for crystallographically oriented magnetite inclusions in silicates (COMIS) in order to explore the conditions of origin of COMIS, and the fidelity with which they record magnetic fields under those conditions. The research plan involves analyzing a number of COMIS in diverse samples in order to evaluate if the results obtained are robust enough to use them as paleomagnetic indicators. If this SGER is successful, the techniques developed for COMIS will then be used for a variety of paleomagnetic applications, including measurement of geomagnetic paleointensity and tectonic applications of paleomagnetic data. The results will also be useful for evaluating the possibility that stable magnetization of the oceanic crust, and of magnetic anomalies on other planets, is due to COMIS.
