Mineralogy, mineral chemistry and thermobarometry of post-mineralization dykes of the Sungun Cu–Mo porphyry deposit (Northwest Iran)

Open Geosciences, 2020
The Sungun copper–molybdenum porphyry deposit is located in the north of Varzaghan, northwestern Iran. The Sungun quartz-monzonite is the oldest mineralized intrusive body in the region and was emplaced during the Early Miocene.

In situ zircon Hf-O isotopic constraints on the genesis of quartz diorite in Narusongduo Pb-Zn mining area, Tibet

, 2021
Narusongduo Pb-Zn deposit is located in the southern margin of the middle Lhasa terrane. The characteristics of the magma source and genetic mechanism of the premetallogenic quartz diorite in the mining zone have not been well explained.

Petrogenesis of Middle Triassic intermediate-mafic igneous rocks in East Kunlun, Northern Tibet: Implications for the crust growth and Paleo-Tethyan orogeny

Geosystems and Geoenvironment
Triassic intermediate-mafic igneous rocks are sporadically exposed in the East Kunlun Orogen Belt (EKOB), and their petrogenesis and geological implications for the Paleo-Tethyan orogeny are not well constrained.
