Magnetite is the most important iron ore in iron oxide-apatite (IOA) deposits which represent the Cu-poor endmember of the iron oxide-copper-gold (IOCG) clan. Magnetite chemistry has been used as a petrogenetic indicator ...

A genetic model for iron-oxide apatite (IOA) and ironoxide copper gold deposits (IOCG) remains elusive. Working hypotheses invoke meteoric fluid, magmatic-hydrothermal fluid, and liquid immiscibility [1,2,3]. Here we report ...

Magnetite is the main constituent of iron oxide–apatite (IOA) deposits, which are a globally important source of Fe and other elements such as P and REE, critical for modern technologies. Geochemical studies of magnetite ...

Iron oxide copper-gold (IOCG) and iron oxide-apatite (IOA) deposits are major sources of Fe, Cu, and Au. Magnetite is the modally dominant and commodity mineral in IOA deposits, whereas magnetite and hematite are predominant ...

Although studies have proposed that iron oxide-apatite (IOA) deposits may represent the deeper roots of some Andean iron oxide copper-gold (IOCG) systems, their genetic links remain obscure and controversial. A key ...

The Candelaria iron oxide-copper-gold deposit in Chile was formed by superimposed, episodic hydrothermal pulses with contrasting composition and temperature, according to micro-textural and compositional variations in ...

The Andean IOCG clan in the Coastal Cordillera of northern Chile, comprises the iron oxide-Cu-Au sensu stricto, the iron oxide-apatite (IOA), and the stratabound Cu(-Ag) deposits, also known as Manto-type Cu(-Ag) ...
