General comments

Subject category Comment text
Deposit PROSPECTS LIE IN SCHIST AND GNEISS COUNTRY ROCK WHOSE FOLIATION TRENDS GENERALLY WNW AND DIPS SW OFF SW LIMB OF SE-PLUNGING ANTIFORM ALONG WOLF CREEK. NORTH AND SOUTH OF PROSPECTS ARE GRANITE DIKES TRENDING GENERALLY EAST-WEST AND WNW-ESE. LONGER DIKE TO NORTH IS CUT BY DIABASE DIKE TRENDING GENERALLY N 25 E. THORIUM VEINS IN THIS AREA ARE ONE OF FOUR ENVIRONMENTS OF TH OCCURRENCE KNOWN IN POWDERHORN 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.
