在学习各家关于扬子地台基底演化论述的基础上,综合大量区域地质调查资料,从基底岩系的沉积特征,构造运动、岩浆活动、变质作用并结合航磁资料,初步探讨基底地壳的演化过程,固结程度,结构特点。通过对“黄陵背斜”区和神农架地区的崆岭群和神农架群的分析对比,从两者的原岩的沉积特征和变质程度,混合岩化作用等的巨大差异性和构造发展特点的一致性论述,认为崆
Based on the exposition of the basement evolution of the Yangtze platform, a large amount of regional geological survey data are synthesized and the evolution of the basement crust is discussed based on the sedimentary characteristics, tectonic movement, magmatism, metamorphism and aeromagnetic data of the basement rock series Process, degree of consolidation, structural characteristics. Through the analysis and comparison of the “Huangling anticline” and “Shennongjia group” in the “Huangling anticline” area and Shennongjia area, from the great differences and tectonic development of sedimentary characteristics and metamorphic degree of the protoliths, Characteristics of the consistency of argument, that 崆
