| Deposit | MANGANESE OXIDES IN PIPELIKE BODIES OF CALLAREOUS AND OPALINE SPRING SINTER . SOME OF THE VEIN MATERIAL IS MN-RICH CHALCEDONY, OTHERS ARE VUGGY MN-RICH QUARTZ. MANY OF THE LATTER TYPE LOOK LIKE THE OUTCROPS OF THE MOHAWK VEIN, AND MAY HAVE BEEN THE REASON FOR SO MUCH PROSPECTING ON THESE DEPOSITS |
