In the Buchim porphyry copper deposit, we determined several representative rare mineral phases, comprising metals from gold-palladium group as well those bismuth-selenium (Cu-Bi-Se-Te-As) group. The phases are represented by new in bismuthinite, galenobismutite, krupkaite, friedrichite, emplectite, laitakarite and native bismuth of gold-palladium, including gold palladium with their elemental ...

Stratabound deposits within late Carboniferous carbonate units in the Middle–Lower Yangtze River metallogenic belt are important copper producers in China. Hitherto, the genesis of these deposits has been debated, due to poor constraints regarding the timing and source of the mineralization. Proposed models include a late Carboniferous seafloor exhalative formation (SEDEX), or an Early Cretaceo...

The Ok Tedi Complex hosts a world-class porphyry copper-gold deposit. Samples from the Ok Tedi Complex and the neighbouring Mount Ian Complex were analyzed for major and trace elements using XRF and HR-ICP-MS, and the isotopic composition of S in sulphides was analyzed by Elemental Analyzer. Major element geochemistry indicates that both complexes are alkaline and contain rocks ranging in compo...

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 Pb-Zn-Cu deposit of Ulldemolins occurs within the Carboniferous sedimentary series of the southernmost Catalonian Coastal Ranges. It consists of sulphide-bearing calc-silicate assemblages, with epidote, Ca-amphiboles and Ca-garnet, which develop selectively along a dolomicrite bed near the contact with a granite porphyry. Two mineralisation styles can be differentiated: a) banded and b) irr...
