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 INTERFINGERING UNITS OF DUBOIS GREENSTONE COUNTRY ROCKS TRENDS GENERALLY N 35 TO 43 E, 80 TO 90 SE. SEQUENCE IS INTRUDED APPROXIMATELY ALONG FOLIATION TREND BY TOLVAR PEAK GRANITE AND CUT ON NE BY CAMBRO-ORDOVICIAN DIABASE DIKE TRENDING N 57 W. NEAR PROSPECT ARE TWO SMALL SYENITE INTRUSIONS. VEIN LIES IN SMALL FAULT TRENDING N 50 E.
