The Mesoproterozoic Kibaran belts host large amounts of mineral resources such as cassiterite, wolframite, gold, and columbite-group minerals (“coltan”), all them in high demand for new technologies related industries. Most these occurrences are linked to the latest early Neoproterozoic G4 granitoid intrusions, also termed “tin(-bearing) granites”. Three main parts constitute belts: Kibaride Be...
The northern flank of the North China Craton (NCC) hosts a linear zone gold, molybdenum, silver, lead, and zinc polymetallic ore deposits. Among these, Yingfang Pb-Zn-Ag deposit is located in central part Yanshan–Liaoxi metallogenic belt (YLMB) which extends for approximately 1000 km forms major mineralized zone. In this study, we characterize mineralization trace genesis based on new sulfur le...
Regional setting and geochronology of the Late Cretaceous Banatitic Magmatic and Metallogenetic Belt
Abstract The 1,500-km-long Banatitic Magmatic and Metallogenetic Belt (BMMB) of Romania, Serbia and Bulgaria is a complex calc-alkaline magmatic arc of Late Cretaceous age. It hosts a variety of magmatic-hydrothermal Cu, Au, Mo, Zn, Pb and Fe deposits, including Europe’s only world-class porphyry-copper deposits. Regional metallogeny can be linked to subduction of the Vardar Ocean during the La...
The Wulonggou Gold Field is one of the giant gold fields in East Kunlun Orogenic Belt, northwestern China. Previous studies mainly focused on elementary mineral isotopic studies, fluid inclusions, and geological features Field. In this study, we report some research precise age specific ore-forming process WGF: hydrothermal monazite U–Pb ages; way precipitation; composition, evolution, source f...
