Figure 2a: Surface showing of the Fission Mine fluorite vein-dike. The blue colouration is the fluorite. Note the apatite crystal in the upper right corner, and also note the flow patterns in the fluorite. (The elongate verticle objects are drill core holes) Photo by J.R. Wakefield (1987)

Figure 2b: From inside the Fission Mine adit. The fluorite vein shows flow patterns. The black mineral in the vein is hornblende. Biotite, with Po halos, is also found at the very east end of the drift. This site is a radioactive mineral location (as are most of the mines from Wiberforce to Bancroft.). The dike is clearly cutting the wall rock and is only a few centimeters in width. Photo by J.R. Wakefield (1987)
