：１∶１０万野外地质填图发现，在措勤地区北侧的白垩系中发育了一系列逆冲推覆构造和褶皱构造，且有侵入岩体分布，又被未变形的火山凝灰岩不整合覆盖。根据侵入岩的钾长石和角闪石及其不整合的火山凝灰岩中蚀变斜长石的ＡｒＡｒ法同位素年龄、沉积物质的组成和沉积地层的空间展布等特征，笔者推测这些逆冲断层和褶皱构造均发育于晚白垩世，并早于第三纪。 : 1: 100,000 wild geologic maps show that a series of thrust nappe structures and folds have been developed in the Cretaceous on the north side of the Cuoqin area, with intrusive rock mass distribution and unconformity of undeformed volcanic tuffs cover. Based on the ArAr isotopic age of altered plagioclase, the composition of sedimentary material and the spatial distribution of sedimentary strata in potash feldspar and hornblende in intrusive rocks and their unconformity volcanic tuffs, the authors speculate that these thrusts Faults and fold structures developed in the Late Cretaceous and earlier than the Tertiary.
