Answer:
The rock texture with aligning parallel platy grains is to exhibit metamorphic foliation.
Most metamorphic rocks have a platy or planar structure which is caused by the parallel alignment of micas and/or other flat mineral so this structure is called foliation.
Metamorphic rocks can be foliated or non-foliated.
Foliated metamorphic rocks will display banding or layering of its mineral constituents while non-foliated metamorphic rocks will not.
