zone of metamorphism

The research of deformation of metamorphic minerals around contact zone indicates the synchroneity of thermal metamorphism and deformation.

通过接触带变质矿物变形特征的研究，揭示了热变质作用与侵位变形的同时性；

Tectogenesis, especially tectonic metamorphism is more important to the formation of the migmatite& metamorphics zone.

构造活动，尤其是构造变质对变质&混合岩带的形成起了相当重要的作用。

And the cause of the gradual increase in the metamorphic degree from the east to the west, besides being influenced by the regional metamorphism, is chiefly influenced by high temperature and high thermal current formed in Tancheng-Lujiang fracture zone to the west of the coalfield.

而由东到西变质程度逐渐增高的原因，除了受区域变质影响外，更主要的原因是受位于煤田西邻的郯庐断裂带所形成的高温、高热流的影响。
