Collaborative Research: Halogen Partitioning in Magmatic Systems

9625517伦敦该项目的目标是继续研究岩浆系统中亲石元素的行为，特别是实验研究卤素在含卤素矿物和共存硅酸盐液体之间的分布。 该建议的重点是控制卤素在硅酸盐液体和黑云母、角闪石、磷灰石和钛铁矿之间分布的一些化学参数。 通过对这些参数的适当评估，这些矿物最终可能被用作不断发展的岩浆热液系统中卤素浓度的直接监测器。 这些知识对于确定卤素在花岗岩相关磁热液矿床形成过程中作为助熔剂和矿化剂的能力，以及更一般地控制其他基本参数，如液体结构、粘度和密度、相关系、扩散、物种形成和元素的液体/流体/晶体分配，具有重要价值。 这是一个合作项目，涉及奥古斯塔纳学院的本科生和俄克拉荷马州大学的研究人员。

9625517 London The goal of this project is to continue studying the behavior of lithophile elements in magmatic systems and specifically to investigate experimentally the distribution of halogens between halogen-bearing minerals and coexisting silicate liquids. This proposal focuses on the some of the chemical parameters controlling the distribution of halogens between silicate liquids and biotite, amphibole, apatite, and titanite. With proper assessment of these parameters, these minerals may eventually be able to be used as direct monitors of halogen concentrations within evolving magmatic-hydrothermal systems. Such knowledge us of great value in determining the ability of halogens to act as fluxes and mineralizers during the formation of granite-associated magnetic-hydrothermal ore deposits and, more generally, to control other fundamental parameters such as liquid structure, viscosity, and density, phase relationships, and diffusion, speciation, and liquid/fluid/crystal partitioning of elements. This is a collaborative project involving undergraduate students at Augustana College and researchers at the University of Oklahoma.
