Zircon SHRIMP U-Pb dating and geochemical characteristics of late variscan granites of the daitongshan copper deposit and lamahanshan polymetallic-silver deposit, southern Daxing’anling, China

Abstract

Daxing’anling(大兴安岭) area is one of the regions that Phanerozoic granites are extremely developed in NW China. At present, the Hercynian granitoid research lags behind the Mesozoic granitoid research. In this article, we have taken systematic petrochemistry and geochronology researches on the Hercynian granitoids in Daitongshan(代铜山) copper deposit and Lamahanshan(喇嘛罕山) silver polymetallic deposit, which were located at southern section of Daxing’anling metallogenic belt. Zircon SHRIMP U-Pb dating results show that, the granite aplites in Daitongshan and the gneissic granites in Lamahanshan were formed at (265±5)-(268±9) Ma and (252±2)-(252.6±3.4) Ma, respectively, which were both the products of late Herynian tectonic-magmatic events. Samples from Lamahanshan are characterized by high SiO₂ (69.72 wt.%-74.65 wt.%), high potassium (3.53 wt.%-4.55 wt.%) and low P₂O₅ (0.03 wt.%-0.12 wt.%), aluminum saturation index (A/CNK) range from 0.95 to 0.98, Rb, Nd and K are enriched, whereas the elements such as Nb, Ta, P and Ti are depleted, which belong to I-type granitoids. Characteristics of samples from Daitongshan are similar to H-type granitoids. The magma source may be mostly originated from the lithospheric mantle component which were transformated or affected by the subduction components, and its formation may be closely related with the subduction and orogenesis of the Paleo-Asian Ocean.
