Abstract Many workers accept a metamorphic model for orogenic gold ore formation, where gold-bearing aqueous-carbonic fluid is an inherent product of devolatilization across the greenschist-amphibolite boundary with majority deposits formed within seismogenic zone at depths 6–12 km. Fertile oceanic rocks that source and metal may be heated through varied tectonic scenarios affecting deforming u...

Detailed knowledge of the lithospheric structure is essential for a better understanding tectonic evolution Xing'an-Mongolian Orogenic Belt (XMOB). We constrained across XMOB by receiver function imaging and shear wave splitting analysis from dense seismic array. The lithosphere-asthenosphere boundary (LAB) coherently imaged in different blocks. mid-lithospheric discontinuity also identified at...

Palynological investigations have been carried out on samples from the Upper Devonian Hongguleleng Formation of Western Junggar, Xinjiang, NW China. In total, 26 miospore species belonging to 19 genera and 28 acritarch assigned recognized lower member Fm. in Bulongguoer section. The palynofloral assemblages, particular taxa, are similar those eastern European early Famennian Corbulispora vimine...
