The Yuleken porphyry Cu-Mo deposit located in the Chinese Altay-East Junggar, a section of Central Asian Orogenic Belt, world's largest Phanerozoic subduction-accretionary orogen, witnessed multistage tectonic-magmatic evolution and mineralization from arc to syn- post-collision environment over time span about 52 Ma. Four types molybdenite have been distinguished: (1) primary magmatic-hydrothe...
A knowledge graph is becoming popular due to its ability describe the real world by using a language that can be understood both humans and machines computer technologies. case study construct of porphyry copper deposits presented in this paper. First all, raw text data collected integrated from selected porphyry-skarn Qinzhou Bay – Hangzhou metallogenic belt, South China. Second, text's entiti...
Copper, obtained from porphyry deposits formed in arc settings, is a critical resource, and primarily sourced magmas. However, the processes that shape copper contents of magmas are up for debate. Existing models place emphasis on different petrological agents explain large-scale trends systematics. Previous studies have noted ’Cu paradox,’ where with high Sr/Y ratios, indicative ore-forming po...
The paper analyzes the approach of St Porphyry Kavsokalivit to ecclesiological issues, in particular his central statement, “The Church is eternal and uncreated”. An attempt determine origins logical justification this concept made. emergence Porphyry’s unusual theological formula relates literal interpretation New Testament metaphor as Body Christ (Eph 1:23, 1 Cor 12). A specific feature disco...
The magmatic process within upper crust encompasses various contents such as the transition between and hydrothermal systems changes in oxygen fugacity (ƒO2), which ultimately play key roles formation of porphyry Cu deposits (PCDs). However, tracing these processes, especially systems, is not an easy task. This study reported detailed fluid exsolution systematical variation ƒO2 a Tongchang–Chan...
the area is located 20 km northwest of kashmar and about 4 km of kalateh taimour in khorasan razavi province. the study area is part of tertiary volcanic-plutonic belt north of daruneh fault and its situation in tectonic inliers between two important active faults, doruneh and taknar. volcanic rocks are mainly intermediate to acid pyroclastic type. they formed during early tertiary. the volcani...
Fadiheh copper-gold prospect area in northwest of Torbat-e Heydariyeh in Khorasan Razavi Province is located in the central part of the Khaf-Kashmar-Bardaskan magmatic belt. This area includes outcrops of Eocene volcanic-pyroclastic units with felsicـintermediate nature. The lavas are andesite and latite, and pyroclastic units include rhyodacitic tuff, andesitic lithic tuff and ignimbrite. Intr...
