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 GENERALLY N 57 TO 67 E, 85 TO 90 SE. FAULT TRENDING N 58 E DISPLACES SCHIST ON NW AGAINST POWDERHORN GRANITE ON SE. GRANITE FOLIATION NEAR FAULT TRENDS GENERALLY N 55 E, 85 TO 90 SE. SECOND FAULT TRENDS N 57 W, DIPS 85 NE, AND IS MAPPED AS QUARTZ VEIN WHERE IT INTERSECTS NE-TRENDING FAULT. FAULT INTERSECTION AND EXTENSIONS OBSCURED BY OLIGOCENE TUFFS.
