Mesozoic molybdenum deposits in the east Qinling–Dabie orogenic belt: Characteristics and tectonic settings

Fluid inclusion and H–O–C isotope geochemistry of the Yaochong porphyry Mo deposit in Dabie Shan, China: a case study of porphyry systems in continental collision orogens

“…The small Cretaceous granitic stocks are often associated with porphyry-type Mo mineralization, such as Xiaofan, Mushan, Dayinjian, Tangjiaping, Qian'echong, and Shapinggou ( Fig. 1), thereby constituting the Dabie Mo belt (Chen and Wang 2011;Mao et al 2011;li et al 2013b). …”

Fluid Inclusion and Oxygen Isotope Constraints on the Origin and Hydrothermal Evolution of the Haisugou Porphyry Mo Deposit in the Northern Xilamulun District, NE China

“…In some of these deposits Mo is recovered as byproduct (i.e., porphyry Cu-Mo (±Au) deposits), whereas, in others, the deposits are characterized by high abundances of Mo but virtually no Cu or Au (i.e., purely porphyry Mo deposits) such as the Climax-type deposits along the North American Cordillera [1][2][3]. China has more than half of the world's molybdenum metal [4], and many of the Mo deposits are similar to the Climax-type Mo deposits where molybdenite is almost the only sulfide [5]. Most of China's Mo deposits are located in the Qinling-Dabie orogenic belt in Central China (>8.5 Mt Mo metal [4,6,7]) and the eastern section of the Central Asian orogenic belt in northeastern China (>11 Mt Mo metal [8,9]).…”

Unlike the Climax-type Mo deposits, which typically develop in backarc or intracontinental rifts and are associated with alkaline magmas [1], the porphyry Mo deposits in the Chinese Qinling-Dabie orogenic belt are related to high-K calcalkaline to shoshonitic magmas generated in syn-to postcollisional tectonic settings and therefore have been suggested to belong to a new class of Dabie-type (or collision-type) porphyry Mo deposits [7,[10][11][12].…”

Petrogenesis of the early Cretaceous intermediate and felsic intrusions at the southern margin of the North China Craton: Implications for crust–mantle interaction

“…Chen et al, 1998;Goldfarb and Santosh, 2014;Guo et al, 2013; J.W. Li and Santosh, 2014;Mao et al, 2011;Zhai and Santosh, 2013). The igneous rocks along the southern margin of the NCC are important for constraining their spatial and genetic relationships with ore deposits (e.g.…”

“…The igneous rocks along the southern margin of the NCC are important for constraining their spatial and genetic relationships with ore deposits (e.g. Mao et al, 2011), crust-mantle interaction and the tectonic evolution of the NCC (e.g. Mao et al, 2010).…”
