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 …

Mobilization involves the translocation and concentration of originally dispersed metallic
constituents; remobilization is the translocation resulting in modified concentration and …

Compositional models of the Earth are critically dependent on three main sources of
information: the seismic profile of the Earth and its interpretation, comparisons between …

A metamorphic devolatilization model can explain the enrichment, segregation, timing,
distribution and character of many goldfields such as those found in Archean greenstone …

The introduction of high temperature, high magnesium komatiitic and picritic magmas into
the Earth's upper crust has given rise either directly or indirectly to many of the world's major …

An attempt has been made to estimate the chemical composition of the earth's primitive
mantle by a critical evaluation of data derived from ultramafic mantle samples and partial …

Trace element analyses have been carried out on hydrothermally altered pillow basalts of
greenschist facies dredged from the median valley of the Mid-Atlantic Ridge. Sr is leached …

Hydrothermally altered pillow basalts dredged from the Mid-Atlantic Ridge, and belonging to
the greenschist facies, have been studied in order to determine the mineralogical and …

A relationship between convergent margin magmas and copper–gold ore mineralization has
long been recognized,,,,,. The nature of the genetic link is controversial, particularly whether …

Reversal experiments have been performed to check the method of Jaques & Green (1980)
to determine equilibrium partial melts from peridotite compositions. Reversals of the Jaques …
