The Philippines site strategically on the Pacific Rim of Fire, that girdle of cordilleran terrain that hosts more copper deposits than any other geologic segment of the world. Given a bit more exploration it is quite possible that I will be able to say the same for gold as well.Gerald ...
Victoria Carbonate‐Base Metal Gold Deposit and Its Significance in the Mankayan Mineral District, Luzon, Philippines deposit is not directly related to the late stage of hydrothermal activity that produced the FSE porphyry copper-gold and the Lepanto enargite deposits. ... FG Sajona,E Izawa,Y...
Porphyry deposits are large, low-grade metal ore bodies that are formed from hydrothermal fluids derived from an underlying magma reservoir. They are important as major sources of critical metals for industry and society, such as copper and gold. However
Most copper is mined or extracted as copper sulfides from large open pit mines in porphyry copper deposits that contain 0.4 to 1.0% copper. Sites include Chuquicamata, in Chile, Bingham Canyon Mine, in Utah, United States, and El Chino Mine, in New Mexico, United States. According to the ...
Porphyry copper deposits, the principal source of copper and molybdenum, form at convergent margins. Copper is precipitated from fluids associated with cooling magmas that have formed in the mantle and evolved at mid- to lower crustal levels, before risi

Geology, Mineralogy, and Formation Environment of the Disseminated Gold-Silver Telluride Bulawan Deposit, Negros Occidental, Philippines The Bulawan deposit is located in the porphyry copper belt of southwest Negros island, Philippines. Propylitic, K–feldspar, sericitic, and carbonate alter... VB Magl...
Where are Porphyry Copper Deposits Spatially Localized? 53 To model the spatial associations between the porphyry plutons and the strike-slip fault discontinu- ities and the batholithic pluton margins, the centroids of each of the 23 mapped porphyry plutons are dig- itized and used in the ...
Short-wave infrared (SWIR) reflectance spectroscopy is a quick and effective method of detecting and characterising hydrothermal alteration associated with ore deposits, and can identify not only mineral species but also changes in the major element composition of minerals. Porphyry deposits represent larg...
Therefore, initial magma enrichment in copper and sulphur, although adding to the metallogenic potential, is not necessary to form a giant deposit. Our results link the respective durations of magmatic and hydrothermal activity from well-known large to supergiant deposits to their metal endowment. ...
