Abstract

Abstract

Xiyingzi granite-body in Guyang area, Inner Mongolia, belongs to calc-alkaline series, bearing the characteristics of island arc affinity.Its petrological geochemistry characteristics are almost similar to those of adakite: SiO₂ content > 56% on average (57.28%-66.63%); Al₂O₃ > 15% (15.93%-18.04%); MgO=1.14%-3.47%, enriched in Na and depleted in K; Na₂O/K₂O=1.16-1.97;Sr content (446-582 μg/g) > 400 μg/g on average and Sr/Y ratio =31.32-103.74, > 20-40;low Y content (5.61-17.4 μg/g, less than 18 μg/g); low Yb (0.42-2.06 μg/g, only one sample's Yb content > 1.9 μg/g); with small positive Eu anomaly and without significantly negative Eu anomaly; REE has a strong differentiation, which belongs to the strong LREE enrichment type; Sr has obvious positive anomaly, while Nb has significant negative anomaly.The laser-plasma mass spectrometry (LA-ICP-MS) was used for the zircon U-Pb dating of adakitic granite in Guyang area and the isotope age was obtained to be 281.9±3.1 Ma (MSWD=3.3), indicating an Early Permian activity.The discovery of adakite in this region provides new clues on the closure time of Paleo-Asian Ocean, and is of great significance to the study of Central Asia Late Paleozoic orogenic belt's tectonic evolution and geodynamics characteristics.It also provides geological and geochemical constraints on resolving the long-term debates on the Inner Mongolia and Paleo-Asian Ocean.
