This work will determine experimentally the partitioning behavior of Sc, Y, La, Sm, Lu, and Ni between ortho- and clino pyroxene and a range of natural mafic silicate magmas. Previous investigations have been on synthetic, rather than natural, melts and at higher temperature. The information obtained will help us to interpret the way that natural magmatic systems have evolved as they rose within the earth.

这项工作将在实验上确定Sc、Y、La、Sm、Lu和Ni在斜方辉石和一系列天然镁铁质硅酸盐岩浆之间的分配行为。以前的研究是关于人工合成的熔体，而不是天然的熔体，并在更高的温度下进行。所获得的信息将帮助我们解释自然岩浆系统在地球内部上升时的演化方式。
