项目摘要
While mid-ocean ridge basalts provide wide-spread samples of the oceanic upper mantle and the chemistry of these rocks potentially constrains mantle temperature and composition, interpreting these constraints requires inversion using petrogenetic models that specify mangle mineralogy, temperature, geochemistry, and dynamics. Oxygen-isotope variations in these basalts have the potential to add important new constraints because oxygen-isotope composition of subducted oceanic crust differs from that of common mantle peridotites such that subduction of crust into the uppermantle can create domains that are both compositionally compositionally enriched in basaltic and sedimentary components and anomalous in delta 018. Detailed sutdies of suites selected to examine the influence of crystallization-differentiation, crustl assimilation, and sub-solidus alteration on the delta 018 of mid-ocean ridge basalts.
虽然洋中脊玄武岩提供了广泛分布的海洋上地幔的样本,这些岩石的化学性质可能会限制地幔温度和成分,解释这些限制需要反演使用岩石成因模型,指定mangle矿物学,温度,地球化学和动力学。 氧同位素的变化,这些玄武岩有可能增加重要的新的限制,因为俯冲洋壳的氧同位素组成不同于普通地幔橄榄岩,使地壳俯冲到uppermantle可以创建域,这两个组成成分丰富的玄武岩和沉积成分和异常的三角洲018。 详细研究了为研究结晶分异作用、地壳同化作用和亚固相线蚀变对大洋中脊玄武岩三角洲018的影响而选择的岩套。
