An euhedral crystal (the biggest one in the photo) in groundmass matter

by Metwally Hamza, Egyptian Geologist, Egypt

- The term euhedral in geology means that the crystal has well-growth sides, such as that appears in this photo as an equent grain. And the term groundmass refers to the very fine-grained material that exists in the whole section.
