【摘要】 在压性和扭性的断裂带中,具有透镜状和圆形状的角砾岩称为磨砾岩。它们的成份是不均一的,由不同成因,不同时代和不同成份的碎块、碎屑和碎基混杂而成。故对于这种岩石,如果不强调结构,只考虑其成份的话,则可称为混杂磨砾岩。并且这个术语也被用来描述压性和扭性的磨砾岩。 本文选择了山东、江苏和江西省的实例,讨论了压性断裂混杂磨砾岩带的野外产状,岩石分带,混杂磨砾岩“壳”,动热交代变质作用和显观—微观构造。更多还原

【Abstract】 In the compressive and shear fracture zones, the breccia which often demonstrates lenticular and cabochon without angular fragment is called one pudding stone. We have found that their components are heterogeneous and mixed by rubbish, fragment and matrix of different genesis, different period and different components. For this rock body, it is therefore considered that the ingredient to be nomenclature if pheno-menon of texture is not emphasized. Starting from this viewpoint, this rock is called one mixed-pudding stone and the term has been used for describing the zones of pudding stones of compressive and shear fractures.In the present paper, the examples are chosen from Shantung, Kiangsu and Kiangsi provinces, and the discussion includes the field occurence, dividing band of rocks, "shell" of mixed-pudding stone, dynamothermal-metasomatic metamorphism and megaso-microstructure ofthe mixed-pudding stone zones of the compressive fractures.更多还原
