Structure, age, and tectonic development of the Huoshishan–Niujuanzi ophiolitic mélange, Beishan, southernmost Altaids

Geochemical and geochronological evidence for a former early Neoproterozoic microcontinent in the South Beishan Orogenic Belt, southernmost Central Asian Orogenic Belt

“…The North Beishan Orogenic Belt is characterized by a complicated collage accretion system of several late Paleozoic island arcs, while the South Beishan Orogenic Belt (SBOB) may record the collision and subduction of several ancient microcontinents (Cleven et al, 2013;Liu et al, 2011;Qu et al, 2011;Song et al, 2013a;Tian et al, 2014;Xiao et al, 2010). The Huaniushan and Shibanshan arcs of the SBOB are the topic of the present study (Fig.…”

Paleozoic magmatism and metamorphism in the Central Tianshan block revealed by U–Pb and Lu–Hf isotope studies of detrital zircons from the South Tianshan belt, NW China

“…28 ocean, which had not opened during this time interval , as evidenced by the absence of respective ophiolites in the STS belt (Huang et al, 2011;Long et al, 2006;Tian et al, 2014;Yang et al, 2011).…”

Geochemical and geomorphological evidence for the provenance of aeolian deposits in the Badain Jaran Desert, northwestern China

“…1), is a typical accretionary orogenic belt within the Altaids, and topographic culmination is Mazong Mountain. Intrusive rocks occur widely, and are main granitic in composition (Tian et al, 2014). The Qilian Mountains is the foreland region of the Northern Tibetan Plateau (NTP), which is a long-lived accretionary orogen formed in response to the closure of an oceanic basin between the Central Qilian and North China plates in the Paleozoic (Yan et al, 2010).…”
