Northern Tibet volcanic field, Volcanic field in Northern Tibet, China
The Northern Tibet volcanic field spreads across the Qiangtang Plateau and Kunlun Mountains with numerous craters and lava flows at elevations above 4700 meters (15,400 feet). The landscape displays various volcanic structures including columnar rock formations and several calderas of different sizes.
Volcanic activity in this region occurred between 15 and 30 million years ago, with formations shaped during the Quaternary period. The magma activity significantly influenced the geological structure of the entire highland area.
Local geologists conduct field research in this remote area to document the geological formations and analyze mineral compositions including andesite and trachyandesite.
Visits require thorough preparation for extreme high altitude conditions, rugged terrain, and minimal infrastructure in the surrounding region. Travelers should prepare for long treks across remote areas with limited shelter and supply options.
The Kekexili caldera measures roughly 4 kilometers in diameter and displays two distinct craters in the Bamaoqiongzong section with prominent columnar rock formations. These rock structures form through specific cooling processes after lava flows and are rarely seen in this configuration.
