Experimental Studies of Melt-Solid Chemical Transport Mechanisms Beneath Mid-Ocean Ridges

格罗夫9415968 实验旨在研究钛，铈，镱，钍，和U在辉石中的扩散计划了解熔融和熔融运输下的洋中脊。 这些信息可以用来解释洋脊喷发的岩浆的成分。 这将导致更好地理解熔化的条件，以及熔化是否发生在平衡或不平衡条件下。 实验将在活塞缸高压炉中进行，其压力和温度与上地幔的熔化有关。 将使用离子微探针对运行产物进行分析。 对可能具有不同速率的元素的扩散速率的测量也可以告诉我们一些关于熔化速率的信息。 ***

9415968 Grove Experiments designed to examine the diffusion of Ti, Ce, Yb, Th, and U in pyroxene are planned to understand melting and melt transport beneath mid-ocean ridges. This information can be used to interpret the composition of magmas that erupt at ocean ridges. This will lead to a better understanding of the conditions of melting, and whether melting occurs under equilibrium or disequilibrium conditions. Experiments will be done in piston cylinder high-pressure furnaces at pressures and temperatures that are relevant to melting in the upper mantle. Analysis of run products will be done with the ion microprobe. The measurement of the diffusion rates of elements that may have different rates could also tell us something on the rate of melting. ***
