The Hongliuhe ophiolite is a fragment of the early Paleozoic oceanic crust situated in a suture zone central to the Beishan orogenic collage, which is a subset to the Central Asian Orogenic Belt in Northwest China. It has lithologic, geochemical and chronological similarities to the Yueyashan–Xichangjing ophiolite 400km east, along strike, allowing for correlative interpretations of marginal seafloor...
The timing and genesis of the major Ni–Cu–Co sulfide deposit in the Xiangshan intrusion have been studied based on newly obtained in-situ U–Pb, Hf and Re–Os isotopic analyses. The SIMS U–Pb zircon ages of the gabbro hosting the Ni–Cu–Co sulfide deposit indicate that the Xiangshan intrusion was emplaced at 279.6±1.1Ma (95% confidence level, MSWD=1.30, n=15). On the basis of combined geological and...
