N2 - The Song Hien Basin in northeast Vietnam is linear- shaped, running in the northwest - southeast direction from Vietnam-China border to the easternmost of Lang Son province; with a total length about 200 km the structure divides the Ha Lang belt to the northeast and Phu Ngu belt in the south and southwest. Permian - Triassic magmatism comprises pluton-volcanic felsic and mafic bimodal magmatic associations, including basalt, gabbrodolerite - dolerite (and lherzolite-gabbronorite); rhyodacite - rhyolite and granite. These magmatic associations are spatially, temporally and genetically related. Detailed mineralogical, geochemical and chemically mineralized studies have been conducted intensively on the Song Hien magmatism; among these, the mafic and ultramafic magmas have been described separately while gabbrodolerites were grouped to pluton-volcanic basaltoidic associations. Formation ages of lhrzolite and gabbro-dolerite are 260-262 Ma, while rhyolite – 246 Ma. Geochemical and isotopic data show genetic relationship between basalts and gabbro-dolerite and rhyolite and porphyric granite. Geochemical features of the Permian Song Hien magmas indicate a uniform evolutional trend for the Permian – Triassic magmas. The Nb, Ta, Sr and Ti depletion is a geochemically streamline character for ultramafic, mafic and felsic rock types, suggesting that their common mantle source may have been contaminated by subduction-derived materialsand are produced by mantle melting following continental collapse that occurred around craton marginal regions under the impact of super-mantle plumes developed under Asian continent.
