| Deposit | THORIUM VEINS IN THIS AREA ARE ONE OF FOUR ENVIRONMENTS OF TH OCCURRENCE KNOWN IN THE POWDERHORN-IRON HILL AREA AND ARE PROBABLY RELATED TO EMPLACEMENT OF LATE PRECAMBRIAN SYENITES NORTH AND WEST OF IRON HILL AND OF YOUNGER LATE PRECAMBRIAN OR CAMBRIAN CARBONATITES AT IRON HILL. FOLIATION OF DUBOIS GREENSTONE COUNTRY ROCK, INCLUDING FELSIC LAYERS AND GRANITE DIKES, TRENDS GENERALLY N 65 TO 72 E. PROMINENT QUARTZ VEIN TRENDS N 50 W BUT TOWARD ITS NW END CHANGES TO N 80 W. |
