There is a north - north - east negative anomaly belt of aerial magnetism in the middle - east part of the basin , which could be displayed by the aerial magnetism of commutative field , upwardly continuation , lvt in earthquakes , the experimentation of granite liquation ( demagnetization ) , the distribution of neozoic era volcanic rock , earthquake , hot spring and ground feature . the anomaly shows the blocking in east - west direction , and it is also associated with intense activity of deep heat interaction and the development of the crust - mantle mixed layer in the north qiangtang 從區域航磁、向上延拓、地震低速層、花崗巖熔融(退磁)實驗、新生代火山巖的分布、地震、溫泉、地貌等發現,盆地中東部存在一北北東向航磁負異常帶,既顯示出東西分塊,也與北羌塘深部熱力作用強烈活動、發育“殼幔混合層”有聯系。
