这是一个关于熔体形状的实验研究 上地幔部分熔体中的包裹体。 这项调查是 动机是观察到,晶体熔体形态的 实验生产的样品不符合 理论上预测的平滑弯曲的晶体-熔体界面。 熔体的几何形状对地震速度有重要影响, 这些数据可以用来模拟上地幔速度 在熔体存在下的结构。 分析数字 将使用运行后样品的背散射电子图像 为了获得所需的参数(例如熔体的长径比 夹杂物,它们的面积,总熔体分数)来计算 地震速度,根据建立的弹性模型, 部分熔融岩石的无弹性和电性质。 这 是一种很有前途的新方法来表征熔体分布 在上地幔系统中。
英文摘要
This is an experimental investigation of the shapes of melt inclusions in upper mantle partial melts. This investigation is motivated by the observation that the crystal-melt morphology of experimentally produced samples is not consistent with theoretically predicted smoothly curved crystal-melt interfaces. The melt geometry has a paramount effect on seismic velocities, and the data can be applied to model the upper mantle velocity structure in the presence of melt. Analysis of digital backscattered electron images of the post-run samples will be used to obtain the parameters needed (such as the aspect ration of melt inclusions, their area, the total melt fraction) to calculate seismic velocities, based on established models of elastic, anelasic and electrical properties of partially molten rocks. This is a promising new approach to characterize the melt distribution in upper mantle systems.
