Subject category Comment text
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 PRECABRIAN SYENITES NORTH AND WEST OF IRON HILL AND OF YOUNGER LATE PRECAMBRIAN OR CAMBRIAN CARBONATITES AT IRON HILL. PRINCIPAL FAULT TRENDING GENERALLY N 35 E DISPLACES BLACK CANYON SCHIST AND GNEISS COUNTRY ROCK ON SE AGAINST PORPHYRITIC SYENITE OF COMPOSITE INTRUSION ON NW, APPARENT RIGHT LATERAL MOVEMENT. GRANITE DIKE INTRUDES SYENITE ON TREND SUBPARALLEL TO FAULT.
