Nyainqentanglha Shan, a 7000 m above sea level mountain that is an uplifted block created
by faults associated with the E-W extension of the Tibetan Plateau.

Leucogranite intrusion

Increasing pressure and temperature during the peak orogenic stage of the collision caused
high-grade metamorphism and eventually led to localized crustal melting and the generation of leucogranites. The sample shows a leucogranitic melt injected into older mica schists.

Chalcopyrite ore (with Pyrite and Galena) from the Qulong Copper Mine. The ore is from a
porphyry-type Cu (Mo, Au) ore belt that is associated with granitic intrusions formed after
continental collision ca. 18-14 million years ago. The Qulong Copper Mine is today the second
largest copper deposit in China.
