9406205 Daines The PI will investigate melt distribution and migration in partially molten anorthosites using synthetic anorthosites in which a glass phase with a composition approximating either a parental magma or a late-stage differentiated melt has been added. Characterization will use optical, scanning and transmission electron microscopy. The data obtained from these experiments are critical for evaluating the efficacy of dynamic models proposed to account for the formation of anorthosites and will provide insight into cumulate maturation and magma chamber processes. ****

小行星9406205 PI将调查熔体分布和迁移在部分熔融的斜长岩使用合成斜长岩，其中玻璃相的组合物接近无论是母岩浆或后期分化熔体已被添加。 表征将使用光学、扫描和透射电子显微镜。 从这些实验中获得的数据是至关重要的动态模型的有效性进行评估，提出解释斜长岩的形成，并将提供深入了解累积成熟和岩浆房过程。 ****
