General comments

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 PRECAMBRIAN SYENITES NORTH AND WEST OF IRON HILL AND OF YOUNGER LATE PRECAMBRIAN OR CAMBRIAN CARBONATITES AT IRON HILL. FOLIATION OF BLACK CANYON SCHIST COUNTRY ROCK TRENDS VARIABLY ENE-WSW TO WNW-ESE, DIPPING VERTICAL TO STEEPLY SE. SMALL TH VEIN TRENDS N 60 E, BUT ITS NE EXTENSION IS COVERED BY MIOCENE BASALT.
