Abstract Magnetite (Fe 3 O 4) is a well-recognized petrogenetic indicator and is a common
accessory mineral in many ore deposits and their host rocks. Recent years have seen an …

The Asian continent formed during the past 800 my during late Neoproterozoic through
Jurassic closure of the Tethyan ocean basins, followed by late Mesozoic circum-Pacific and …

Many workers accept a metamorphic model for orogenic gold ore formation, where a gold-
bearing aqueous-carbonic fluid is an inherent product of devolatilization across the …

Apatites from the major types of mainly magmatic-hydrothermal mineral deposits (30
localities, mostly in British Columbia, Canada) together with apatites from carbonatites (29 …

The ubiquity of Au-bearing arsenian pyrite in hydrothermal ore deposits suggests that the
coupled geochemical behaviour of Au and As in this sulfide occurs under a wide range of …

Porphyry Cu systems host some of the most widely distributed mineralization types at
convergent plate boundaries, including porphyry deposits centered on intrusions; skarn …

Pyrite is one of the most common minerals in many precious and base metal hydrothermal
ore deposits and is an important host to a range of trace elements including Au and Co and …

Metals such as Cu, Mo, Au, Sn, and W in porphyry and related epithermal mineral deposits
are derived predominantly from the associated magmas, via magmatic–hydrothermal fluids …

Formation of hydrothermal ore deposits requires a fluid with the capability to transport and
deposit metals, and the sources and physical and chemical characteristics of these …

Porphyry copper deposits are currently the world's largest source of copper and
molybdenum, and are also among the largest reservoirs of gold in the upper crust. Despite …
