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.

最近的探索模型暂时确定了Guelb Moghrein Fe-Cu-Au-Co沉积物是铁氧化物铜金（Feox-Cu-Au）矿床的亚型。这些存款中有许多直到最近才被发现。因此，结论性，通常适用的遗传模型很少。这项研究的区域，矿石沉积相关方法将集中于壁岩石的岩石学，变化和矿石矿物学以及矿石沉积的结构。地球化学，同位素和流体包容性工作将有助于解释矿石流体的性质和起源。了解区域P-T进化是制定区域构造模型的先决条件，该模型解释了矿石形成的结构控制。在沉积量表上，必须检查变形和变化样式之间的相互作用，以获取有关流体流动模式和流体/岩石比率的信息。这项研究的目的是为Guelb Moghrein沉积开发遗传模型，并将其与当前为Feox-Cu-AU类别的沉积物类别提出的模型进行比较。
