The MSA-pegmatite Listserv is an announce-only list serve. It was created by the Pegmatite Interest Group (PIG) that is comprised of individuals who share a fascination with and appreciation of the mineralogy and petrology of pegmatites. Whatever your background or level of involvement, you are welcome to participate. The list serve allows the group leader to send the members announcements and occasional news. It is not set up to allow members to send messages.
