dynamometamorphic rocks

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。
