The newly discovered three alkali|rich intrusive rock belts in the Mt. Kunlun Mt. Altun region of southern Xinjiang are the Lapeiquan|Yitunbulak alkali|rich intrusive rock belt, the Gez|Taxkorgan alkali|rich intrusive rock belt and the Beilisai|Abulash alkali|rich intrusive rock belt. The former two belts were formed during the Yanshanian period, and the third one was formed during the Himalayan period, which is the youngest alkali|rich intrusive rock belt in China. The discovery of the alkali|rich intrusive rock belts is of great significance in shedding light on the history of tectono|magmatic activities in this region.
