sarcheshmeh porphyry copper deposit is located 65 km southwest of rafsanjan in kerman province. the sarcheshmeh deposit belongs to the southeastern part of urumieh-dokhtar magmatic assemblage (i.e., dehaj-sarduyeh zone). intrusion of sarcheshmeh granodiorite stock in faulted and thrusted early-tertiary volcano-sedimentary deposits, led to mineralization in miocene. in this research, the mass ch...

In our previous study on petrogenesis of quartz syenite and granite porphyry, the host rocks Late Mesozoic Shapinggou Mo deposit in Qinling–Dabie orogenic belt, we found that initial Sr isotopic composition is strongly affected by degree K-alteration. Here, provide further evidence their minerals to investigate geochemical behaviour trace elements isotopes during alteration explain phenomenon d...

Long-standing debates exist over the timing and mechanism of uplift of the Tibetan Plateau and, more specifically, over the connection between lithospheric evolution and surface expressions of plateau uplift and volcanism. Here we show a T-shaped high wave speed structure in our new tomographic model beneath South-Central Tibet, interpreted as an upper-mantle remnant from earlier lithospheric f...

At El Chucho creek, located to the west of Valle del Cauca department in Colombia, some hydrothermal alterations affecting Buga Batholith rocks and dykes porphyritic quartz-dioritic tonalitic composition were identified. These lithological units host mineral occurrences pyrite, chalcopyrite, molybdenite that occur disseminated or associated with quartz veinlets. The identified phyllic, propylit...

Abstract Our pilot study reveals potential Li isotope fingerprints recorded in the Mesoproterozoic ( c. 1.4–1.1 Ga) kimberlites, lamproites and lamprophyres from Eastern Dharwar Craton Paleocene (62 Ma) orangeite Bastar India. The new data are interpreted context of available composition lamproitic to lamprophyric rocks occurring Variscan (Bohemian Massif) Alpine–Himalayan (SW Tibet) orogenic b...

The Pulang porphyry copper deposit (PCD), one of the main potential areas for resource exploration in China, exhibits typical alteration zoning. However, further investigation indicative significance minerals, additional insight into metallogenic characteristics, and prospecting guidelines continue to be challenging. In this study, ASTER WorldView-3 data were used map hydrothermal minerals by e...
