The developments in stratigraphy are involved in the division of the surveyed area into the gangdise - nyainqentanglha - tengchong stratigraphic province and bangong - nujiang suture zone ; subdivision of the bangong - nujiang suture zone into the nyainrong microcontinent and jueweng - yulashan - xagquka m lange zone ; redivision of the nyainrong microcontinent and lagongtang formation ; re - establishment of the gajia formation ; reconstruction of the guoqu group ; disintegration of the muggar kangri group into three group complexes 摘要地层方面，将测区地层划分为冈底斯腾冲地层区和班公错怒江结合带，班公湖怒江结合带中又划分出聂荣微地块和觉翁余拉山下秋卡混杂带两个小区；按变质岩调查方法解体了聂荣地块；对原大面积分布的拉贡塘组进行了有效的解体；新建立嘎加组；恢复了郭曲群；将木嘎岗日岩群解体出3个岩组。
