项目摘要
1160854SmirnovThis Division of Earth Sciences Instrumentation and Facilities Program grant supports acquisition of a 2G Enterprises 4K-755 high-resolution superconducting rock magnetometer (SRM) with a small access bore (6 mm) at Michigan Technological University. The small bore SRM allows for paleomagnetic directional and paleointensity analysis of single crystals of ancient (Precambrian) silicates hosting magnetic and paramagnetic fine grained mineral inclusions. These igneous phase single crystals are likely to hold the most pristine record of Earth?s early magnetic field and yet to date very few reliable paleointensity measurements from Precambrian rocks have been made. The analytical sensitivity now available with a small bore SRM makes proposed measurements possible. The PI is in possession of numerous plagioclase separates from Precambrian dikes sampled around the word (e.g., the ~2.45 Ga Burakovka dikes (Russia), the ~2.9 Ga Munni-Munni intrusion and the ~2.42 Ga Widgiemooltha dikes (Western Australia), the ~2.37 Ga Bangalore dikes and the ~2.2 Ga Mahhubnagar dikes (India), and the ~1.1 Ga Portage Lake basalts (USA)) from previous NSF/EAR research support. The PI is well poised to immediately make use of the requested small bore SRM for NSF/EAR funded research on the nature of Earth?s early magnetic field with implications for Precambrian tectonics and the generation and early behavior of the geodynamo; the magnetic field which shields the Earth surface from the highly energized solar wind and allowed for the evolution of Earth?s biota. This instrument will be only the second of its kind in a U.S. academic laboratory. The infrastructural impacts of this acquisition are very significant for the U.S. paleomagnetic research community. The instrument will complement existing paleomagnetic analysis equipment in the PI?s lab and serve an active student research group including an active PI-undergraduate mentoring program at MTU.***
1160854Smirnov地球科学仪器和设施计划资助部门支持密歇根理工大学购买一台2G企业4K-755高分辨率超导岩石磁强计(SRM),该仪器具有小口径(6毫米)。小口径SRM可以对古(前寒武纪)硅酸盐单晶进行古地磁定向和古强度分析,其中含有磁性和顺磁性细粒矿物包裹体。这些火成岩相单晶可能保存着地球早期磁场的最原始记录--S,但迄今为止,对前寒武纪岩石进行的可靠古强度测量很少。小口径SRM现在提供的分析灵敏度使建议的测量成为可能。PI拥有许多与世界各地前寒武纪岩脉(例如,~2.45Ga Burakovka岩脉(俄罗斯)、~2.9Ga Munni-Munni侵入体和~2.42Ga Widgiemooltha岩脉(西澳大利亚)、~2.37Ga班加罗尔岩脉和~2.2Ga Mahhubnagar岩脉(印度))分离的斜长石,以及来自以前NSF/EAR研究支持的~1.1Ga波蒂奇湖玄武岩(美国)。PI已经做好了充分准备,可以立即利用美国国家科学基金会/EAR资助的小口径SRM进行地球性质的研究?S早期磁场,对前寒武纪构造和地球发电机的产生和早期行为的影响;屏蔽地球表面不受高能量太阳风影响的磁场?S生物群。这将是美国学术实验室中的第二台此类仪器。这一收购对美国古地磁研究界的基础设施影响非常重大。该仪器将补充皮?S实验室现有的古地磁分析设备,并为活跃的学生研究小组提供服务,包括山大活跃的皮-本科生指导计划。*
