Answer
Dear Jose

Good Morning and Fraternal Greetings.
Sorry for the delay in my reply as I am on Out of Station for the last one Week.

This is very difficult for me to identify the Rock through the image you have sent. It should be seen with naked eye along with some of the physical tests to clearly identify the Rock sample. Mineral/Rock is identified by some of the physical properties like color, streak, luster, hardness and it's specific gravity. Hence, identification of mineral's name through image is sometimes deceptive.
