Geochronology and geochemical characteristics of the Shangdan pluton in the northern margin of the Alxa Block, Inner Mongolia and its tectonic implications

Gan, Lisheng; Wu, Tairan; Chen, Yan; Zhang, Wen; Zhang, Zhao Yu

Description

The Northern Alxa Orogenic Belt is the southernmost segment of the Central Asian Orogenic Belt. The less investigated Shangdan pluton is a key point to understanding its tectonic evolution. The granodiorites from this pluton yield zircon LA-ICP-MS U-Pb ages of 331. 7 +/- 0. 9Ma, which is the earliest age obtained for the Late Paleozoic plutons in the Zongnaishan-Shalazhashan tectonic zone and indicates an Early Carboniferous magmatic event. The granodiorites from the Shangdan pluton have...[Show more]
