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

Geochronology, geochemistry, and Sr–Nd–Hf isotopes of the early Paleozoic igneous rocks in the Duobaoshan area, NE China, and their geological significance

“…In addition, some ore bodies in the Duobaoshan deposit are intruded by two-mica granite with a weighted mean 206 Pb/ 238 U age of 219 ± 1 Ma (our unpublished data), indicating that both the deposits must be formed before 219 Ma. Considering these geological characteristics of both deposits and new geochronological data we obtained together, we think that both the deposits must be formed after 447 Ma but before 219 Ma rather than between Permian and Triassic, as previously believed (Du et al, 1988;Han et al, 2004) or during the early Ordovician, as recently thought (Ge et al, 2007a;Cui et al, 2008;Xiang et al, 2012;Liu et al, 2012;Zeng et al, 2014).…”

“…The ore and gangue minerals, ore fabrics, wall-rock alterations, and mineralizing processes of both the deposits have been well described by Liu et al (2012) and Zeng et al (2014). More details see references (Liu et al, 2012;Zeng et al, 2014).…”

“…They suggested that both the granodiorite and the granodiorite porphyry were emplaced between the Permian and the Triassic and that both the Duobaoshan deposit and the Tongshan deposit formed during the Permian of the late Paleozoic (Du et al, 1988(Du et al, , 2010. Ge et al (2007a), Cui et al (2008), Xiang et al (2012) and Zeng et al (2014) published zircon SHRIMP or LA-ICP-MS U-Pb ages of 485 ± 8, 480 ± 5, 478 ± 4, and 482 ± 4 Ma, respectively, for the granodiorite; Xiang et al (2012) and Zeng et al (2014) reported zircon LA-ICP-MS U-Pb ages of 475 ± 5 and 477 ± 4 Ma, respectively, for the granodiorite porphyry; Xiang et al (2012), Liu et al (2012) and Zeng et al (2014) published molybdenite Re-Os ages of 475 ± 5, 486 ± 4, and 476 ± 9 Ma, respectively. These researchers thought that the host intrusive rocks of the Duobaoshan deposit were formed in the early Ordovician and that both the deposits also formed during the early Ordovician.…”

“…Most of previous researchers thought that these ore-bearing intrusions emplaced during the Early Permian and that the two deposits were formed in the Late Paleozoic (Du et al, 1988;Han et al, 2004). Recently, many new geochronological data by zircon SHRIMP and LA-ICP-MS U-Pb dating for the granodiorite and the granodiorite porphyry and Re-Os dating for molybdenite or sulfide in the Duobaoshan area have been published (Ge et al, 2007a;Cui et al, 2008;Liu et al, 2012;Xiang et al, 2012;Zeng et al, 2014). These new geochronological data indicate that both the granodiorite and granodiorite porphyry were emplaced during the Early Paleozoic and that the Duobaoshan deposit was the Early Paleozoic in age.…”

“…Zhang et al, 2008), and also is an important polymetallic metallogenic belt hosting different types of hydrothermal deposits (Liu et al, 2001;Mao et al, 2003;D.G. Zhai et al, 2009;Wu et al, 2011b, c;Liu et al, 2012;Zhou et al, 2012;D.G. Zhai et al, 2013), mainly including porphyry, skarn, and epithermal ore deposits that are spatially and temporally associated with the Mesozoic felsic magmatism (Zhao and Zhang, 1997;Mao et al, 2003;F.…”
