Abstract: This paper gives a brief introduction about the concepts and field resea- rch method of structural analyses of granites,presents some of the most use- ful criteria for distinction between flow fabric and deformed fabric,and indi- cates the geologicai significance of strain analyses with an example.It is undoubtedly very important to integrate structural analyses with petrological and geochemical studies in order to gain a more comprehensive understand- ing of granites as a chemical systems and also as a physical system.
