本文主要从岩石学的角度论述了两条韧性剪切带内的岩石岩相学特征，讨论了韧性剪切带以及剪切带内岩石的特征。 - The main conclusions and cognitions are as follows : ( l ) rockmass weathering should be studied from either microcosmic and macrocosmic , microcosmic contain includes of mineralogy and of lithology , and in macrocosmic , weathering action damages integrality of rockmass , so studying rockmass structure can open out weathered degree of epigenetic - surface rockmass . ( 2 ] the dissertation sums up the characteristic indexes which can token weathered and unloaded degree , simultaneously , puts forth and summerizes several methods that classifies different weathered and relaxed zones of slope rockmass . ( 3 ) river valley epigenetic - surface reformation is controlled by rockmass structure , but weathering and unloading of rockmass is the direct cause which leads to different epigenetic - surface physical geology phenomena , for example , collapse , landslide , incline , dynam - relaxed and so on
本文主要结论与认识为： ( 1 )对于岩体风化的研究从微观与宏观两方面入手，微观方面重视对矿物学、岩石学的研究，宏观方面，上升到岩体结构被改造的高度进行研究； ( 2 )归纳了表征岩体风化、卸荷程度的特征指标并提出了划分岩体风化、卸荷程度的几种方法； ( 3 )岩体结构控制着河谷浅表改造，但导致崩塌、滑坡、倾倒、松动等表生物理地质现象的直接原因乃是岩体的风化、卸荷。
