Deposit THIS REPORT REPRESENTS A MERGER OF ORIGINAL RECORD M050013 WITH RECORD D000757 OF JAMES ELLIOTT AND JAN WILT IN MOLYBDENUM FILE, CONTACT PERSON T.G. THEODORE, USGS. THIS RECORD ALSO CONTAINS DATA FROM DUPLICATE RECORD D000310 OF ROBERT KING WHICH HAS BEEN DELETED FROM MRDS. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
Deposit ANOTHER OREBODY WAS 800 BY 200-400 BY 15-40 FT, PERPENDICULAR TO BEDDING, LOCALIZED ALONG AXIS OF SHALLOW ANTICLINE TRENDING N10W. THE CLEAREST ASSOCIATION OF ORE WITH A FOLD IS WHERE THE MAIN MANTO ORE BODY LIES ALONG AN ANTICLINAL FLEXURE BETWEEN THE 700 AND 1300 LEVELS. THE MAIN MANTO FOLD DIES OUT A SHORT DISTANCE ABOVE THE 700 LEVEL BUT THE ORE BODY CONTINUES WITH THE SAME TREND ALMOST TO THE SURFACE.
