Comments on the location information

  • (LAND STATUS AND ADMINISTRATIVE AREA LOCATIONS CALCULATED USING GIS OVERLAY ANALYSIS FOR SAN JUAN N. F.). NELSON-MOORE AND OTHERS (1978) GIVE LOCATION AS SEC. 15, BUT BLM SMM BASE MAP AND MINE LOCATION ON TOPO SHEET SUGGEST LOCATION IN SEC.15 (UNSURVEYED). SAME LOCATION AS OR CLOSE TO SOUTH BARLOW MINE. ; INFO FROM LAND.ST :1975

Subject category Comment text
Deposit GENERALLY NE-DIPPING TRIASSIC TO JURASSIC SEDIMENTARY SECTION IS CUT BY NE-SW-TRENDING PYROXENE LAMPROPHYRE DIKE AND BY GENERALLY NORTH-SOUTH-AND NE-SW-TRENDING FAULTS. MINE IS LOCATED ON DIKE NEAR CONTACT BETWEEN ENTRADA SANDSTONE AND PONY EXPRESS LIMESTONE MEMBER OF WANAKAH FM. IF DEPOSIT IS SIMILAR TO THAT AT GRAYSILL MINE 4 MILES TO SE (SAN JUAN CO.), ROSCOELITE ORE AND POSSIBLY CARNOTITE ARE ASSOCIATED WITH CARBON TRASH IN ENTRADA SANDSTONE. MINERALIZATION MAY HAVE BEEN INFLUENCED BY PROXIMITY TO SILLS AND DIKES AROUND FLATTOP MOUNTAIN AND HERMOSA PEAK.
