<strong>Uranium</strong> <strong>ore</strong>-<strong>forming</strong> <strong>systems</strong> <strong>of</strong> <strong>the</strong> Lake Frome regionFigure 6.6: EDAX spectrum collected from ningyoite pseudomorphing apatite(?) and <strong>the</strong>surrounding kaolinitic matrix, in organic-rich material.Figure 6.7: XRD diffraction pattern <strong>of</strong> uraninite-rich material showing <strong>the</strong> presence <strong>of</strong> pyriteassociated with marcasite, uraninite and phosphates. Phosphates are less abundant than in<strong>the</strong> organic-rich material. Fl-Cr = fl<strong>ore</strong>ncite-crandallite, K = kaolinite, Ma = marcasite, N =ningyoite, Qtz = quartz, Py = pyrite, Py-U = pyrite + uraninite, R = rhabdophane.Page 72 <strong>of</strong> 151
