Welcome to the Street Prophets Coffee Hour. This is an open thread at the intersection of religion and politics where we can share our thoughts and comments about the day. I thought we’d start out with some pegmatite minerals.
Pegmatite minerals are interesting because they contain exceptionally large crystals. In addition, they sometimes contain minerals that are seldom found in other kinds of rocks. One of the displays in the Mineral Museum on the campus of Montana Tech in Butte features mineral specimens from the W.C. van Laer Collection featuring pegmatite minerals from Montana and Idaho.
