cutting early Qtz 1 veins and the assemblage Src 1 -Chl 1 -dominated pre-ore alteration. (E) U 1
associated with Chl 2 , Cal 2 , and Hem 2 cutting the assemblage Src 1 -Chl 1 -dominated pre-ore
alteration. (F) Post-ore Kln 1 alteration obliterating texture of the pre-ore and syn-ore mineral
assemblage.
Qtz 2 quartz has Hem 3 hematite inclusions (Fig. 4.9C) and displays irregular contours
(Fig. 4.10C) that suggest partial dissolution during a late alteration event. Qtz 2 quartz
displays similar morphology to those recognized in sandstone of the Athabasca and
Kombolgie basins (Hiatt and Kyser. 2000; Polito et al., 2005; Hiatt et al., 2007). Pressure
solution features such as grain-point contacts and sutured grain boundaries are well
developed and locally forming stylolites. Kln 1 kaolinite alteration is pervasive and fills
well-developed secondary porosity (Fig. 4.10E) where it partially replaces detrital Ms 0
muscovite (Fig. 4.10D). The morphology of the Kln 1 kaolinite varies from coarse-grained
vermiform to very fine-grained (Fig. 4.10E). Aggregates of Ttn 1 titanite are disseminated
and generally associated with altered Mzn 0 monazite (Fig. 4.10B).
4.5.1.2.3. Uranium mineralization
The ore alteration stage in the basement overprints the pre-ore alteration assemblage.
Crosscutting relationships indicate that the syn-ore assemblage cross cuts Qtz 1 quartz veins
and the pre-ore alteration assemblage Src 1 sericite and Chl 1 chlorite (Fig. 4.9D). U 1
Uraninite is spatially associated with, or rimmed by Chl 2 chlorite, Cal 2 calcite, and Hem 3
hematite (Fig. 4.9E). Cpy 2 chalcopyrite and minor Gn 1 galena are associated with the U 1
uranium mineralization.
