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 …

Orogenic gold deposits have formed over more than 3 billion years of Earth's history,
episodically during the Middle Archean to younger Precambrian, and continuously …

Epigenetic gold deposits in metamorphic terranes include those of the Precambrian shields
(approx 23,000-25,000 t Au), particularly the Late Archean greenstone belts and …

Metamorphic belts are complex regions where accretion or collision has added to, or
thickened, continental crust. Gold-rich deposits can be formed at all stages of orogen …

The association of large Au–Cu–Ag ore deposits with convergent margins is commonly
attributed to the higher content of chalcophile elements in the parental magmas generated at …

This volume presents new data on a group of gold deposits that are hosted primarily within
or in the immediate wall rocks to intrusions, and which have recently been suggested to …

Partial melting at continental lithosphere depths plays an important role in generating
geochemical variations in igneous rocks. In particular, dehydration melting of ultrahigh …

Laser-ablation ICPMS has become widely accessible as a powerful and efficient multi-
element microanalytical technique. One of its key strengths is the ability to analyse a wide …

Economically exploitable deposits of metallic minerals (ore deposits) form in the Earth's crust
through a variety of geologic processes. These involve extraction of metals at low …

There are six distinct classes of gold deposits, each represented by metallogenic provinces,
having 100's to> 1000 tonne gold production. The deposit classes are:(1) orogenic gold;(2) …
