The Xenoliths

These black xenoliths can be very big, Frank de Wit once found a 100kg+ one. They are partly very crumbly, you can split them easily with your hands. They show a lot off little holes filled with Sanidine (coral form), Cristobalite (tiny balls) , Glimmer (Biotite?) and sometimes really tiny white Zircon trees. You have to enlarge properly to see the Zircons, otherwise you'll miss them.
