| Abstract: | The four primary modes of microscopic occurrence of uranium in the Katemcy and Streeter granites of central Texas as revealed by fission track  mapping are: 1) in accessory minerals; 2) along grain boundaries; 3) in microfractures; and 4) in quartz and feldspars. Most of the uranium occuring in the first three modes, accounting for more than three-fourths of the total, appears to be readily mobilized during weathering. |
