Geology of the Ox Lake Cu - Mo porphyry deposit
2010The Ox Lake copper-molybdenum deposit is locallized in the margin and contact zone of a Late Cretaceous granodiorite porphyry. Hazelton Group rocks, including a lower Felsic Tuff, a middle Andesitic Tuff and an upper Sandstone-SiItstone, are country rocks in the area.

Tectono-Magmatic Precursors for Porphyry Cu-(Mo-Au) Deposit Formation
Economic Geology, 2003Porphyry Cu-(Mo-Au) deposits are relatively rare but reproducible products of subduction-related magmatism. No unique processes appear to be required for their formation, although additive combinations of common tectono-magmatic processes, or optimization of these processes, can affect the grade and size as well as the location of the resulting ...

The Shaxi porphyry Cu-Au deposit, Anhui Province, eastern China
2005The middle and lower Yangtze valley is one of the most important metallogenic regions in Eastern China, where more than 200 polymetallic Cu-Fe-Au, Mo, Zn, Pb, Ag deposit occur. The Shaxi porphyry Cu-Au deposit is located in the central Anhui Province, and is related to Jurassic-Cretaceous intrusions. Measured sulfur isotope compositions of sulfides are

Mineral prospectivity mapping of porphyry Cu deposit using VIKOR method
2020Naysian Porphyry Cu District (NPCD) is situated at the northeast of Isfahan, in the center of Iran along the Urumia-Dokhtar Magmatic Assemblage (UDMA) belt. Mineral Potential Mapping (MPM) is an important issue in mining to reduce the exploration costs by proposing a layout of drilling over the most favorable regions in association with ore-bearing ...

The Dinkidi Cu-Au porphyry deposit is located in northern Luzon, Philippines. The 110 Mt deposit is characterised by high gold grades (ave. 1.2 g/t Au and 0.5% Cu) and is one of only a few alkaline porphyry deposits to have been discovered outside British Columbia. Alkaline magmatism in northern Luzon is related to the Late Oligocene rifting event that

Abstract The Zaldivar porphyry copper deposit, Northern Chile, consists of two major intrusions, the 290 Ma Zaldivar, and the more recent Miocene (38.7 Ma) Llamo porphyry. Five types of inclusions have been identified in quartz phenocrysts from Llamo porphyry, including melt inclusions (M), and four types of fluid inclusions, called MS (multi solids),

Abstract Precambrian porphyry type Cu±Mo±Au deposits are present in many parts of the world including Australia, Brazil, Canada, China, Finland, India, Namibia, Russia, Sweden, and Zambia. Most of them are associated with calc-alkaline or alkaline subduction zone volcanics or granitoids of the I-type.

Origin of the Cenozoic porphyry Cu deposits in southern Tibet
2014The Gangdese magmatic belt features extensive Cenozoic magmatic rocks that record geodynamic changes related to the India–Asia collision starting at ~55–50 Ma. Paleocene–Eocene magmas throughout the belt have similar continental arc features. Their intrusive rocks have intermediate [La/Yb]N and intermediate-to-low Sr/Y ratios, negative Eu anomalies ...
