Structural Controls of Uranium Mineralization in the Basement of the Athabasca Basin, Saskatchewan, Canada

Figure 7

Kinematic indicators on drill core samples from Sue (a, b, and c) and Spitfire (d), illustrating (a) crack-seal mineralization in drill hole S835@366 m. (b) Interpretation of (a): pitchblende is hosted in oblique/sigmoidal quartz veins lenses (crack-seal) that run parallel or subparallel to the foliation. (c) Slickensides. Reverse dextral kinematics is deduced from (a) and (c). (d) Slickensides on drill core sample from Hook Lake ([email protected] m) indicating reverse sinistral motion.
