Dear Fatemeh,
Let me add my 2 cents in this discussion.
What is the possibility of these inclusions to be marking an early
foliation? Most of them seems to be oriented and they could be ilmenite or
quartz definind this early stage or earlier foliation.
If my idea has any meaning, you will probably find similar inclusions in
other grains either with similar shape or even similar orientation.
