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 …

Global data for measured Fe 2 O 3/FeO ratios and Cu contents in unaltered volcanic and
intrusive arc rocks indicate that, on average, they are slightly more oxidized than other …

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

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 …

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 …

More than half of the 25 largest known porphyry copper deposits, defined in terms of
contained copper metal, formed during three time periods: the Paleocene to Eocene …

Formation of hydrothermal mineralization is related to the late stages of, or immediate
following, orogenic compressional regimes that have been superimposed on arc …

Iron oxide-copper-gold (IOCG) deposits, defined primarily by their elevated magnetite and/or
hematite contents, constitute a broad, ill-defined clan related to a variety of tectono …

The major, minor and trace element chemistry of chlorite were evaluated as a tool for
mineral exploration in the propylitic environment of porphyry ore deposits. Chlorite from …

The Yulong porphyry copper belt is the most significant porphyry copper belt in Tibet and is
located in the Qiangtang terrane of the Himalayan-Tibetan orogen. The terrane is a collage …
