Ore Metals and Chlorine in Felsic Magmatic Systems

本研究的第一部分是对钛-熔体体系中钨、钼和其他选定的矿石和微量元素的行为进行现场分析和实验研究。关于钛矿和熔体之间的矿石金属随氧气的变化而分配的实验将使pi能够：1)检验关于天然钛矿的SRXF分析和其他研究得出的矿石金属行为的假设；2)模拟不同火成岩钛矿/钛铁矿比例对熔体向成矿流体中Mo和W分配效率的影响。第2部分是关于硅酸盐熔体和含水流体之间元素的分配。第三部分是对拉克兰褶皱带（LFB）火成岩的卤素化学fO2和形成深度的研究，作为对其理论找矿潜力进行更大研究的开始。这项研究代表了从第一性原理评价世界上研究最透彻的花岗岩带之一的成矿潜力的一个开端。

Part 1 of this research is a field-analytical and experimental study of the behavior of tungsten, molybdenum, and other selected ore and trace elements in titanite-melt systems. Experiments on the partitioning of ore metals between titanite and melt as a function of oxygen will allow the PIs to: 1) test hypotheses concerning ore metal behavior that results from SRXF analyses of natural titanites and other studies; 2) model the effect of varying igneous titanite/ilmenite ratios on the efficiency of Mo and W partitioning from melts into ore- forming fluids. Part 2 is on the partitioning of elements between silicate melts and aqueous fluids. Part 3 is a study of the halogen chemistry fO2 and depth of formation of the igneous rocks of the Lachlan Fold Belt (LFB) as the start of a larger study of their theoretical ore-potential. This study represents a start in the evaluation of the ore-potential, from first principles, in one of the best-studied belts of granitic rocks in the world.
