项目摘要
Award is for measuring He, Ne, and Ar noble gases and CO2 content on step-crushed basaltie quench glasses from the Southeast Indian Ridge (SEIR) to examine how noble gases fractionate in the mantle, knowledge essential to understanding mantle melt extraction and volatile transport. This work will also examine heterogeneity in mantle 40 Ar/36 Ar, possibly arising from suduction of atmospheric Ar, and will also investigte the so-called He-paradox, wherey melt samples whose parental material originated from deep within the earth (characterized by high 3He/4He and associated with mantle plumes) have low He abundances, as well as the He flux seemingly having little to do with heat flux from the mantle (as represented by magma production). Samples from the Southeast Indian Ridge have been chosen for the study as they show smooth variation in composition away from the Amsterdam-St. Paul mantle plume that coincides with changes in ridge axial depth. These samples therefore represent a unique sample set to examine the influene on sub-oceanic mantle noble gas systematics by a deep mantle plume acting on the mantle processes underneath a spreading ridge.
该奖项是为了测量来自东南印度洋海岭(SEIR)的分步破碎玄武岩淬火玻璃上的He,Ne和Ar惰性气体和CO2含量,以研究惰性气体如何在地幔中破碎,了解地幔熔体提取和挥发性运输的必要知识。 本工作还将研究地幔40 Ar/36 Ar的不均匀性,这可能是由大气Ar的俯冲引起的,并将解释所谓的He悖论,即熔体样品的母体物质来自地球深处(以高3 He/4 He为特征,与地幔柱有关)具有低He丰度,以及He通量似乎与来自地幔的热通量(如岩浆产生所代表的)没有什么关系。 从东南印度洋海岭的样本已被选定为研究,因为他们显示出平滑的变化,从阿姆斯特丹-圣保罗地幔柱,与海岭轴向深度的变化相吻合的组成。 因此,这些样品代表了一个独特的样本集,以检查的影响,亚大洋地幔惰性气体系统的深地幔柱作用于地幔过程下的扩张脊。
