The iron oxide (Cu-U-Au-REE) deposit class is accepted as an empirical category of ore deposits classification. This class includes Fe deposits that are barren in respect to Cu and Au (e.g. magnetite ±apatite deposits such as Kiruna, Sweden) and deposits that contain these two latter metals (i.e. iron oxide Cu-Au deposits or IOCG deposits). The aim of the proposed research project is to determine the ages and investigate the characteristics, controls, and origin of the Mantoverde IOCG deposit and selected magnetite(-apatite) deposits in northern Chile. The project will address unresolved questions such as: ¿ the source, composition and evolution of ore-forming fluids, ¿ the source of the metals, ¿ the ore forming processes, ¿ the role of coeval magmatism, ¿ the types and characteristics of alteration and their spatial distribution relative to the ore, ¿ the precise ages of alteration and mineralization, and ¿ the possible relationships between Cu-Au bearing (IOCG) systems and Fe-oxide-only systems. The ultimate goal of the investigation is to elucidate the processes, which control the Cu-Au mineralization in these iron oxide-rich systems.

铁氧化物（Cu-U-Au-REE）存款类被认为是矿床分类的经验范畴。这类矿床包括不含铜和Au的铁矿床（如磁铁矿±磷灰石矿床，如瑞典基律纳）和含有后两种金属的矿床（即氧化铁Cu-Au矿床或IOCG矿床）。拟议的研究项目的目的是确定年龄和调查的特点，控制和起源的Mantoverde IOCG存款和选定的磁铁矿（磷灰石）矿床在北方智利。该项目将解决尚未解决的问题，如：成矿流体的来源、组成和演化，金属的来源，成矿过程，同时代岩浆作用的作用，蚀变的类型和特征及其与矿石有关的空间分布，蚀变和矿化的精确年龄，以及Cu-Au轴承（IOCG）系统和铁氧化物只有系统之间的可能关系。研究的最终目的是阐明这些富铁氧化物体系中控制铜金矿化的过程。
