[QUOTE="Lefty, post: 485004, member: 2976"] Is it possible for basalt magma to have punched through a pre-existing tourmaline pegmatite and carried it to the surface in the magma? I have some very similar basaltic-looking rocks with pyrope garnets, some kind of mica and black spinel embedded in them in near identical-looking little "capsules" in the rock. I believe that the pyrope garnets and pleonaste form differently the tourmaline, just wondering if that was a possibility? [/QUOTE]
