| Result | UP TO 0.019% U3O8 AND 0.23% EU. URANIFEROUS SAMPLES ALSO HAVE HIGH AS, BE, HG, MO, PB, SB, W, ZN, ZR. BACKGROUND RADIOACTIVITY IS 200 TO 400 CPS (45-90 UR) IN RHYOLITE AND LESS THAN 200 CPS (45 UR) IN OVERLYING SEDIMENTARY ROCKS. RADIOACTIVITY IS BETWEEN 400 AND 4000 CPS (90-880 UR) IN A ZONE OF OUTCROPS FROM ROCK CREEK TO A POINT ABOUT 1500 KM SW OF ROCK CREEK. RADIOACTIVITY RUNS BETWEEN 500 AND 2000 CPS (110-440 UR) ALONG ROCK CREEK FOR ABOUT 300 M IN A N 50 W DIRECTION. |
