项目摘要
This study proposes to extend work on processes and sources of continental margin magmas, with particular reference to the central Andes (volcanic) and Sierra Nevada (plutonic) provinces. Focussing on the inclusions will allow the PIs to: 1) better constrain the compositions of magmatic and crustal components; 2) evaluate timescales of contamination by examining the length scales over which isotopic equilibration of included material has occurred; 3) better estimate the composition of the mantle source to continental margin magmas - in particular whether the lithosphere or asthenosphere is the predominant source; 4) mass balance the contributions of crustal versus mantle-derived components to evaluate the extent of intra-crustal recycling. As a result, a much better understanding should be gained of the processes affecting magmatic composition in continental-margin arcs.
这项研究建议扩展关于大陆边缘岩浆的过程和来源的工作,特别是关于安第斯山脉中部(火山)和内华达山脉(深部)省。对包裹体的关注将使pi能够:1)更好地约束岩浆和地壳成分的组成;2)通过检查所含物质发生同位素平衡的长度尺度来评估污染的时间尺度;3)更好地估计地幔源到大陆边缘岩浆的组成,特别是岩石圈还是软流圈是主要来源;(4)质量平衡地壳和幔源分量的贡献,以评估地壳内再循环的程度。因此,对影响大陆边缘弧中岩浆成分的过程应该有更好的了解。
