UNPUBLISHED COBALT REPORT
| Subject category | Comment text |
|---|---|
| Deposit | ONLY ONE CO ANALYSIS: CRYPTOMELANE CARRIES 0.08% CO OXIDE; MORE ASSAYS OF MANGANESE OXIDES SHOULD BE MADE FOR COBALT. |
| Deposit | DEPOSITS ARE DIVIDED INTO 5 GROUPS: (1) STEEPLY DIPPING QUARTZ VEINS, (2) QUARTZ VEINS ALONG BEDDING, (3) MANGANESE-RICH REPLACEMENT DEPOSITS, (4) CONTACT METASOMATIC MAGNETITE DEPOSITS, AND (5) SEDIMENTARY PHOSPHATE BEDS. THE STEEPLY DIPPING QUARTZ VEINS ARE FISSURE VEINS WHICH CUT BOTH THE BATHOLITH AND SEDIMENTARY ROCKS AND WERE MINED FOR AG, ZN AND PB. THE BEDDING PLANE QUARTZ VEINS ARE COMMON IN THE N PART OF THE DISTRICT. THESE VEINS HAVE YIELDED MUCH HIGH GRADE AG. REPLACEMENT DEPOSITS RICH IN MANGANESE ARE IRREGULARLY DISTRIBUTED IN FAVORABLE HOST BEDS ALONG MANY STEEPLY DIPPING QUARTZ VEINS, THE BORDER OF THE BATHOLITH, AND THE REDEMPTION FAULT. THE PHOSPHATE BEDS CROP OUT ON THE W FLANK OF THE BROAD PHILIPSBURG ANTICLINE. THE CONTACT METASOMATIC IRREGULAR MAGNETITE PODS OCCUR IN MARBLE ALONG THE BORDER OF THE BATHOLITH AND ALONG A PREINTRUSION HIGH-ANGLE REVERSE FAULT. |
