Owing to lack of isotope age evidence and no correct differentiation of Late Permian thermal contact metamorphic rocks and Himalayan dynamometamorphic rocks from pre-Sinian regional metamorphic rocks, for a long time there have existed many difficulty and problems in the classification of the crystalline basement in the Panzhihua-Xichang (called Panxi for short) area.
长期以来,由于同位素年龄依据不足和没有正确区分晚二叠世热接触变质岩、喜马拉雅期动力变质岩与前震旦纪区域变质岩,攀西地区结晶基底的划分存在许多困难和问题。
Clastic sedimentary rock is a main kind of rock in sedimentary formation in the crust, and it is necessary to standardize classification and naming of its ductile dynamic metamorphic rocks.
根据新疆觉罗塔格碎屑质韧性动力变质岩的形变相变方式、构造、结构组成和粒度结构，将碎屑质韧性动力变质岩划分为６大类：片岩类、板状变粒岩类、糜棱岩类、压扁拉长岩类和布丁岩类，讨论了碎屑质韧性动力变质岩的组合与命名。
