I think the foliation is resulted from deformation. The original composition of the foliatedrock is granite.
我认为岩石中的这些片理是由于岩石变形造成的,片理化岩石的原岩就是花岗岩。

The experimental results show that weak plane of foliated rocks has a marked effect on rock ultimate strength.
试验结果表明,层状岩石的弱面对岩石的强度值有明显的影响。

Accordingly, we think it necessary to consider anisotropic properties of foliated rocks as one of the important factors in each test of rock ultimate strength.
