文摘
- •
We conduct CPO analyses in quartz domains where mica phases form interconnected weak layers.
- •
A negative relationship exists between mica grain connectivity and quartz CPO intensity.
- •
Second phases inhibit effective recovery in quartz.
- •
Weaker quartz CPO textures also occur where second phase dragging is absent.
- •
Mica layers localise strain more effectively than the matrix, as a function of the interconnectivity of grains.
