Intrusives associated with porphyry copper deposits

, 1977
Porphyry copper deposits and their associated intrusives are widespread throughout the world and particularly abundant in the circum-Pacific region, although not all parts contain porphyry copper deposits.

Physicochemical Attributes of Parental Magma in Collisional Porphyry Copper Systems; Using Biotite Chemistry, Case Study: Chahfiruzeh Porphyry Copper Deposit

Journal of Economic Geology, 2019
Introduction Almost all of the well-known porphyry copper deposits in Iran occur within the Kerman Cenozoic magmatic arc (KCMA) (Fig 1) in the southeastern part of Cenozoic Urumieh–Dokhtar magmatic belt (Hassanpour et al., 2015). The Miocene Chahfiruzeh

Element Migration of Mineralization-Alteration Zones and Its Geological Implication in the Beiya Porphyry–Skarn Deposit, Northwestern Yunnan, China

Applied Sciences
Porphyry and the associated skarn-type deposit is one of the most important types of ore deposits worldwide, which usually exhibit significant zoning of mineralization-alteration, but the research on element migration in these mineralization-alteration ...

Geochronology and fluid evolution of the Qulong porphyry system: Implications for porphyry deposit formation

, 2016
Understanding the metal enrichment process and rate in porphyry Cu systems (PCS) is critical to underpin the genetic model of PCS and refine the template for exploration, of which robust temporal constrain is the key.

Determination of geospatial criteria and prediction of potential areas for porphyry copper deposits in Kazakhstan

Frontiers in Earth Science
Determining spatial parameters related to mineral deposits is crucial for analysing mineral prospectivity. These spatial parameters, called Geospatial Criteria (GC), can serve as input data for modelling mineral prospectivity.

Trace elements and melt inclusion in zircon within the Qunji porphyry Cu deposit: Application to the metallogenic potential of the reduced magma-hydrothermal system

Open Geosciences
The Qunji porphyry copper (Cu) deposit, located within the Awulale metallogenic belt (AMB) in the western Tianshan orogenic belt, exhibits distinct geochemical and mineralogical characteristics that have not been fully understood.

Multiple Porphyry Events at Cerro de Pasco, Central Peru

, 2015
Cerro de Pasco, part of the Miocene metallogenic belt of central Peru, is one of the largest known epithermal base metal deposits. The deposit formed along the eastern margin of a diatreme-dome complex emplaced in the Mid-Miocene.

The skarn to porphyry transition : establishing links between skarn and porphyry-type mineralization at New Craigmont, British Columbia

The historic Craigmont Cu-Fe skarn deposit is British Columbia’s highest grade copper mine, producing 36.4 Mt of 1.29% Cu from 1961 to 1982. Although it is located on the southern margin of the Guichon Creek batholith, also home to the Highland Valley ...
