The ummixing of liquids in silicate-carbonatite, silicateborate, silicate-fluoride and silicate-phosphate systems will be investigated using the high temperature, high-pressure centrifuge furnace and autoclave. The partitioning of major elements, trace elements and oxygen isotopes between the immiscible liquid pairs will be determined using microprobe, ICP-AES and ICP-MS techniques. Additionally, the kinetics governing the separation of immiscible liquids and potential disequilibrium partitioning will be investigated. Applications will be made in igneous petrogenesis of P-rich magmas as well as a systemisation of results in order to examine the relationship between structure, energetics and partitioning.

将利用高温高压离心炉和高压釜研究硅酸盐-碳酸盐岩、硅酸盐-硼酸盐、硅酸盐-氟化物和硅酸盐-磷酸盐体系中液体的混合。采用微探针、ICP-AES和ICP-MS技术测定不混溶液对中主元素、微量元素和氧同位素的分配。此外，动力学控制分离的不混相液体和潜在的不平衡分配将被研究。将应用于富p岩浆的火成岩成因，并将结果系统化，以检验结构、能量学和划分之间的关系。
