Genesis of the Guelb Moghrein Iron-Copper-Gold-Cobalt Mineralization, Mauritania

最近的勘探模式初步确定了Guelb Moghrein Fe-Cu-Au-Co矿床为氧化铁铜金（FeOx-Cu-Au）矿床的一个亚类型。其中许多矿藏是最近才被发现的。因此，结论性的、普遍适用的遗传模型是稀缺的。本研究的区域性、与矿床相关的方法将侧重于围岩的岩石学、蚀变和矿石矿物学以及矿床的结构。地球化学、同位素和流体包裹体工作将有助于解释矿石流体的性质和来源。了解区域P-T演化是建立解释构造对成矿控制的区域构造模型的先决条件。在矿床尺度上，研究变形和蚀变类型之间的相互作用是获得流体流动模式和流体/岩石比信息的必要条件。本研究的目的是为Guelb Moghrein矿床建立一个成因模型，并将其与目前提出的FeOx-Cu-Au类矿床的模型进行比较。

Recent exploration models have tentatively identified the Guelb Moghrein Fe-Cu-Au-Co deposit as a sub-type of the class of Iron-Oxide Copper-Gold (FeOx-Cu-Au) deposits. Many of these deposits have only recently been discovered. Therefore, conclusive, generally applicable genetic models are scarce. The regional, ore deposit-related approach of this study will focus on the petrology of wall rocks, the alteration and ore mineralogy, and the structure of the ore deposit. Geochemical, isotope, and fluid inclusion work will aid the interpretation of the nature and origin of the ore fluids. Understanding of the regional P-T evolution is a prerequisite for the formulation of a regional tectonic model that explains the structural control on ore formation. On the deposit scale, it is essential to examine the interplay between deformation and alteration style to gain information on fluid flow patterns and fluid/rock ratios. The aim of this study is to develop a genetic model for the Guelb Moghrein deposit and compare this with models currently proposed for the FeOx-Cu-Au class of deposits.
