- W2373868193 abstract "The volcanic rocks from the Carboniferous Batamayineishan Formation are widely distributed in eastern Junggar. Petrology,geochemistry and isotope geochemistry of the rocks indicate that: 1) They have widely varied rock types including basalt- andesite- dacite- rhyolite rocks and are of high-K calc-alkaline,enriched in large ion lithophile elements(LILE)(Sr,K,Rb,Ba,Th) and LREE and depleted in high field strength elements(HFSE)(Nb,Ta,Ti)and HREE. Besides,the initial values of 87Sr/86Sr and 143Nd/144Nd are low and the eNd(t) values generally vary in range of 3.0~6.2. All these features suggest that they are immature back-arc basin volcanics related to subduction; 2) The parent magma of the volcanic rocks mainly derived from the depleted mantle with involvement of minor juvenile lower crust comprised of remnants of Paleozoic oceanic crust and island arc system. The genesis of basic lavas may be attributed to a mixing process by hybridization of depleted mantle-derived magma and a small amount of juvenile crust-derived magma,which was related to partial melting of mantle wedge induced by fluid and sediments of subducted oceanic crust. Distinguished from the basic ones,the acid lavas originated from mantle-derived magma,coupled with strong fractional crystallization and crust contamination. 3) Consistent with regional geological background and discovered fossils,the Sm-Nd isochron age of 319.7±5.9 Ma can represent the time of eruption of the volcanic rocks. Based on comprehensive analysis,it is inferred that subduction of the Paleo-Asian Ocean was still underway at the time of 320 Ma and the final closure of the ancient Junggar ocean basin occurred in the period 320 to 311 Ma. Enriched in ore-forming substances,the intensified magmatism during this process made the eastern Junggar region of great prospecting potential." @default.
