The Dongxiang tungsten–copper deposit is a large W–Cu located in the northeast of Jiangxi province south China. Previous studies have mainly considered geochemical and isotopic attributes ore deposit, but information still lacking on genesis setting mineralization-related intrusive rocks. This paper presents systematic elements Sr–Nd–Hf data granodiorite porphyry. porphyry intermediate–acidic c...

The Ascutita porphyry Cu-Mo prospect is located in the SW Poiana Rusca Mountains, Romania. Current assessment estimates a resource of 110 Mt @ 0.15 % Cu-equivalent. In relatively low-grade deposits such as this, by-products Ag (2–3 ppm) are important determining economic feasibility overall orebody. Assayed Cu and have clear downhole correlation. absence other silver-bearing minerals, or correl...

The study area, located in the southern section of the Central Iranian volcano–sedimentary complex, contains a large number of mineral deposits and occurrences which is currently facing a shortage of resources. Therefore, the prospecting potential areas in the deeper and peripheral spaces has become a high priority in this region. Different direct and indirect methods try to predict promising a...

Quartz is one of the most abundant minerals. Used in a variety materials, it preserves geological history and reflects alteration conditions. Data were collected (>2400 data points) from more than 40 ore deposits to understand its internal texture geochemistry. Cathodoluminescence imaging technique for examining quartz that may reveal information about crystal’s origin evolution. The dominan...

The Wunugetushan large porphyry Cu–Mo deposit in NE China is hosted by Mesozoic quartz monzonite and has a Mo-rich core Cu-rich rim space. In this paper, melt inclusions intrusions fluid different-stage veins were studied to explore potential parameters leading decoupling. Melt have rhyolitic compositions of 71.7–85.3 wt.% SiO 2 , 1.9–31.3 ppm Cu 1.7–2.6 Mo. Hydrothermal activity occurred over ...

Abstract Porphyry Mo deposits are important suppliers of molybdenum for industrial applications, but the origin and source metals in these remain debated. Here, we present isotope data Miocene mineralized porphyritic monzogranites (MPMs) Paleocene barren biotite tuffs (BMTs) from Bangpu porphyry (Cu) deposit Gangdese metallogenic belt. The results show that MPMs display radiogenic Sr Pb isotope...

The paper reviews and summarizes data on the physicochemical parameters chemical features of mineralizing fluids at porphyry deposits Cu–Mo–Au system. calculated average values ranges in mineral-hosted fluid inclusions are as follows: temperature 90–957 °C, 388 °C; salinity 0.1–88.0 wt % equiv. NaCl, 29.4 NaCl; density 0.38–1.85 g/cm3, 0.93 g/cm3. highest maximum homogenization temperatures wer...
