| Deposit | NUMEROUS PEGMATITE DIKES AND SILLS OR DIKES OF GRANODIORITE INJECTED INTO METASEDIMENTS OF AULD LANG SYNE GROUP. DIKES AND SILLS HAVE GREATLY DISTORTED THE METASEDIMENTS. THESE ROCKS HAVE BEEN ALTERED 6-12 INCHES FROM THE PEGMATITE, AND STAINED BY LIMONITE. PEGMATITE IS WHITEHIGHLY FRACTURED WITH FELDSPAR CONVERTED ALMOST ENTIIRELY TO CLAY |
