Comparison of mineralization of the Sungun and Kighal porphyry copper deposits, NW Iran: with an emphasis on fluid inclusion studies

Journal of Economic Geology, 2019
Introduction Nowadays, more than half of the word’s copper production is obtained from porphyry copper deposits, large (greater than 100 Mt), low- to moderate-grade, disseminated, stockwork-veinlet, carrying at least trace elements, such as molybdenum ...

Using PGE geochemistry to assess magma fertility in the Polo Sur and Penacho Blanco porphyry copper deposits, Centinela District, Northern Chile [PDF]

, 2020
The Centinela District is host to several mineralized porphyries, including both Cu-only and Cu-Au deposits. This study focusses on the known Polo Sur and Penacho Blanco porphyry Cu +/- Mo deposits as cases of study to assess their Cu-Au fertility ...

A Comparative Study of Porphyry-Type Copper Deposit Mineralogies by Portable X-ray Fluorescence and Optical Petrography

, 2020
Porphyry-type deposits are crucial reserves of Cu and Mo. They are associated with large haloes of hydrothermal alteration that host particular mineral assemblages.

Systematization of u-pb zircon ages of granitoids from the copper porphyry deposits on the urals

Литосфера, 2017
There is a generalization of U-Pb age of zircons from the copper-porphyry deposits of the eastern slope of the Urals. Approved reserves of the largest ones are about 1.4-1.8 Mt of Cu (at an average content of 0.4-0.6 wt % of Cu).

Geophysical exploration of disseminated and stockwork deposits associated with plutonic intrusive rock: a case study on the eastern flank of Colombia’s western cordillera

Earth Sciences Research Journal, 2012
<p>Disseminated deposits are low-grade, large tonnage deposits which are mainly mined for gold, copper, molybdenum and tin. These deposits are normally associated with intermediate to acid plutonic intrusive rocks and all are characterized by ...
