| Deposit | VEINS AND VEINLETS OF MN OXIDES CUTTING HORNBLENDE ANDESITES (GONZALEZ, 1956) AND/OR BASALT MEMBERS OF THE COMONDU VOLCANICS (WILSON, 1956.) PRINCIPAL VEINS RANGE FROM 10-50 CM IN WIDTH. MOST ARE VEINLETS ONLY 1-10 CM WIDE. AVE STRIKE: N 20-25 W WITH DIP OF 50-70 SW. A LESS PROMINENT SYSTEM OF VEINLETS STRIKES N 50 W TO DUE W AND DIPS 50-70 NE TO N. VEINLETS TEND TO RETICULATE ALONG BOTH STRIKE AND DIP. SPACING BETWEEN VEINLETS RANGES FROM A FRACTION OF A METER UP TO 2-3 METERS. IRREGULAR SECONDARY ENRICHMENT ZONE AT SURFACE OF OUTCROPS CONTAINS NUMEROUS VEINLETS OF MN MINERALS. ECONOMICALLY EXPLOITABLE ORES CONSIST OF OXIDES, MAINLY PSILOMELANE AND PYROLUSITE, WITH LESSER AMOUNTS OF MANGANITE AND WAD. MN-SILICATES KNOWN TO OCCUR INCLUDE BUSTAMITE, FOUND IN TWO OPEN CUTS, AND POCKETS OF RHODONITE, MANGANITE AND PYROLUSITE AT CATA LUISITA. HOLLANDITE AND RAMSDELLITE ALSO REPORTED. GANGUE MINERALS INCLUDE: GYPSUM, QUARTZ, RARE CALCITE AND DOLOMITE, ARAGONITE, HEMATITE, AND LIMONITE. |
