Mesozoic molybdenum deposits in the East Xingmeng orogenic belt, northeast China: characteristics and tectonic setting

Geochronology and metallogenesis of porphyry Mo deposits in east-central Jilin province, China: Constraints from molybdenite Re–Os isotope systematics

“…1b). Although the geological characteristics and metallogenic chronology of the deposits have been examined previously (e.g., Ge et al, 2007;Li et al, 2009;Wang et al, 2009Wang et al, , 2011Sun et al, 2012;Zeng et al, 2012Zeng et al, , 2013Zhang et al, 2013;Zhou et al, 2013Zhou et al, , 2014, it is unclear whether the ore-forming materials originated from an oceanic plate, the lower crust, or the upper crust. To resolve these questions, we conducted Re-Os isotope dating and analyzed the Re geochemistry of the Mo deposits.…”

Early Cretaceous adakitic granites and mineralization of the Yili porphyry Mo deposit in the Great Xing’an Range: implications for the geodynamic evolution of northeastern China

“…This area is also well known for its widespread distribution of Mesozoic igneous rocks, commonly known as the Great Xing'an Range Mesozoic Igneous Province (Sengör and Natal'in 1996). Most deposits found in this area are closely associated with Mesozoic magmatic hydrothermal activity, together with porphyry, skarn, hydrothermal veins, and epithermal-type deposits (Zhao and Zhang 1997;Chen et al 2007;Zeng et al 2012). The degree of exploration is relatively high in the southern segment of the Great Xing'an Range, with Pb-Zn, Ag, Cu, Mo, Sn, and rare earth element (REE) deposits (Qin et al 1999;Chu et al 2002;Li et al 2007;Niu et al 2008;Zhou et al 2010;Zhai et al 2010;Wu et al 2010;Liu et al 2010a).…”

Zircon U–Pb geochronology and Sr–Nd–Pb–Hf isotopic constraints on the timing and origin of Mesozoic granitoids hosting the Mo deposits in northern Xilamulun district, NE China

“…1). Many studies have been carried out during the past decade in order to identify the geological characteristics, isotopic ages, ore genesis, origin and evolution of the associated intrusions as well as the corresponding geodynamic settings (Chen et al, 2008;Qin et al, 2008Qin et al, , 2009Shu et al, 2009Shu et al, , 2014Wan et al, 2009;Yan, 2009Yan, , 2012Zeng et al, 2010Zeng et al, , 2012Zeng et al, , 2013Zeng et al, , 2014Zhang et al, 2009aZhang et al, , 2010aZhang et al, , b, 2012Liu et al, 2010;Zhou et al, 2010Zhou et al, , 2012Wu et al, 2011aWu et al, , 2014Ma et al, 2013;Meng et al, 2013;Sun et al, 2013). The findings of some of these studies have shown that the Mo mineralization in the southern part of Xilamulun can be clustered into three groups, i.e., 250-210, 180-150 and 140-110 Ma (Zhang et al, 2009a).…”
