| Deposit | DUMORTIERITE OCCURS ALONG 2 NORTH-TRENDING ZONES OF HYDROTHERMALLY ALTERED QUARTZ-SERICITE RHYOLITE, PARTS OF WHICH WERE INTENSELY ALTERED DURING TWO PHASES WHICH FIRST PRODUCED THE ANDALUSITE, THEN THE DUMORTIERITE BY REPLACEMENT OF ANDALUSITE (ACCORDING TO KERR AND JENNEY, 1935). DUMORTIERITE OCCURS AS (1) COARSE EUHEDRAL BLUE CRYSTALS, (2) MATTED LAVENDAR OR PINK MASSES, AND (3) FIBROUS PINK VEINS OR ISOLATED PINK CRYSTALS. HAND-SIZED CHUNKS OF DUMORTIERITE WERE SO VALUABLE THAT THEY WERE COBBED AND SAVED. VEINLETS WERE NOT MINED BECAUSE OF EXCESSIVE CONTAMINATION OF QUARTZ AND ALBITE. |
