Sanjiang Volcanic Rocks — Yunnan, May 2025

🏔️ Disuga, Sanjiang Region — May 2025

Field investigation of **Triassic volcanic rocks** in the Sanjiang (Three Parallel Rivers) belt, northwestern Yunnan — part of the Paleo-Tethys arc magmatic system. The outcrop near **Disuga** sits at **>4,600 m** elevation, exposing a sequence of basaltic andesites interbedded with volcaniclastic deposits. At this altitude, I experienced **severe acute mountain sickness** — but it was worth it. 🏔️
