Re–Os and 40Ar/39Ar ages of the Jiguanshan porphyry Mo deposit, Xilamulun metallogenic belt, NE China, and constraints on mineralization events

Re–Os sulfide (chalcopyrite, pyrite and molybdenite) systematics and fluid inclusion study of the Duobaoshan porphyry Cu (Mo) deposit, Heilongjiang Province, China

“…The molybdenites of the Duobaoshan deposit have a Re concentration (303-822 lg/g, that is higher than most porphyry deposits in China and in the world (Hu, 1988;Huang et al, 1994;Mao et al, 1999;Zhang et al, 2005;Hou et al, 2006;Berzina and Korobeinikov, 2007;Li et al, 2007;Wu et al, 2011). Mao et al (1999) suggested that the Re content of molybdenite could reflect the material source of the deposits.…”

Molybdenite Re–Os and muscovite 40Ar/39Ar dating of the Xihuashan tungsten deposit, central Nanling district, South China

“…Peng et al, 2006;Wu et al, 2011a;Xie et al, 2007). In comparison with Ar-Ar ages, the Re-Os chronometer of molybdenite is considered to be more robust because the Re-Os isotope system is less sensitive to hydrothermal and metamorphic overprinting (Selby and Creaser, 2001a,b;Stein et al, 1998Stein et al, , 2001.…”

Geology, geochemistry and tectonic setting of the Indosinian Mo deposits in southern Great Hinggan Range, NE China

“…Several major NNE‐ to NE‐striking faults have been identified throughout this region, including the Derbugan Fault, the Hegenshan–Heihe Suture, and the Xar Moron–Changchun Suture (Fig. B; F. Y. Wu et al ., ).…”

“…Due to their economic and scientific significance, these Yanshanian Mo deposits have been extensively studied (e.g. Chen et al ., ; Wu et al ., ; Wan et al ., ; Zeng et al ., , ; L. C. Zhang et al ., ; Liu et al ., ; H. Y. Wu et al ., ), and been attributed to lithospheric thinning and crustal extension in east China (Cui et al ., ; Wu et al ., , ; Liu et al ., ) caused by the joint effect of intra‐plate events: the closure of the Mongol–Okhotsk Ocean in the northwest (Tomurtogoo et al ., ; Kelty et al ., ), and the subduction of the Pacific Plate in the southeast (Nie et al , ; Liu et al ., ). These deposits are mainly related to granite porphyry, rhyolite porphyry, granodiorite porphyry and plagiogranite porphyry, with host strata of the Late Palaeozoic volcanic–sedimentary rocks and Mesozoic continental volcanic–clastic formation.…”
