Alkali magmatism in the North Daba Mountains, China

Congratulations to our visiting student Xianqing Guo finishing her PhD study. On 5th of August, she gave a talk on multi-stage alkali magmatism in the North Daba Mountains, South Qinling, which is part of her PhD project. She illustrated the tectonic framework of the Qinling orogenic belt. Systematically results of petrology, geochemistry, geochronology, isotopic compositions and spatial distribution of the alkali volcanic rocks in the target area were presented, which would contribute to understanding the geological evolution of the Qinling orogenic belt.
