Deposit	THORIUM VEINS IN THIS AREA ARE ONE OF FOUR ENVIRONMENTS OF TH OCCURRENCE KNOWN IN 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 TOLVAR PEAK GRANITE COUNTRY ROCK TRENDS GENERALLY N 35 TO 45 E, 75 TO 90 NW. PRINCIPAL TH VEIN TRENDS N 67E, WITH SMALL BRANCH AT NE END TRENDING N 27 E. BOTH VEINS TERMINATE ON CAMBRO-ORDOVICIAN DIABASE DIKE TRENDING N 58 W. PRINCIPAL TH VEIN TERMINATED ON SW BY CONTACT BETWEEN GRANITE AND FELSITE.
