Constraints on Magma Chamber-Hydrothermal Interaction from the Seamail Ophiolite (Oman)

该项目将在逐个露头的基础上，对层状堆积辉长岩和席状岩脉杂岩之间的Smail蛇绿岩中精心挑选的少量地壳分段进行精确测绘和广泛取样。其目标也是获得全面的构造、结构、矿物学和流体/岩石化学信息，所有这些信息都在与岩浆-热液接触有关的精确定义的空间背景下进行。了解岩浆房边缘的质量和能量转移的速率和机制，对于了解海底热液循环和脊峰岩浆室演化的方式和活力是必要的。该项目将利用最初开发的模型来研究与特征良好的斑岩铜矿床有关的侵入深成岩浆热液系统。

This project will precisely map and extensively sample, on an outcrop by outcrop basis, a small number of carefully selected crustal subsections in the Semail ophiolite between the layered cumulated gabbros and the sheeted dike complex. The goal is too obtain comprehensive structural, textural, mineralogical, and fluid/rock chemical information, all within a precisely defined spatial context, related to magma-hydrothermal contacts. Knowledge of the rates and mechanisms of mass and energy transfer across magma chamber margins is necessary to understanding the style and vigor of submarine hydrothermal circulation and ridge- crest magma chamber evolution. This project will utilize models initially developed to study magma hydrothermal systems related to intrusive plutons associated with well-characterized porphyry copper deposits.
