Foliation is particularly pronounced.

叶理特别发育。

Let us keep walking perpendicular to the trend of foliation to get more details.

我们垂直这些片理化岩石的走向穿越一段并作详细观察。

The effect of the different stresses on the trend of foliation and high stress area;

差应力大小与层理分布和应力集中区的关系；

In addition, the presence and absence of foliation are an other factor to classify fault rocks.

除此之外，是否具有片理构造是划分断层岩的另一个因素。

I think the foliation is resulted from deformation. The original composition of the foliated rock 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。
