Abstract:

The macroscopic mark of strain has not been discovered yet in some granitic masses,but quartz and orthoclase in these rocks obviously have a phenomenon of stress-mineral and quartz[0001]and mica(001)have shown the preferred orientation.In orientation diagrams of quartz[0001]and mica (001)appear ac girdles and they are caused hy plastic deformation in the granitic mass.

Some primary fabrics often exist in granite,in one case they were pro- duced by magmatic flowage,and in another case they were produced by changing of magmatic temperature-gradient.
