Figure 2.9. Microphotograph of typical mineral assemblages and crosscutting relationships
from the Ace-Fay-Verna, Cinch Lake and Gunnar uranium deposits: A: Cataclasite with
mylonitized fragments, Qtz 1 , Kfs 1 in a matrix composed of ±U 1 , Qtz 1 , Cal 2 , Hem 3 , Chl 3 , Src 2 ,
Cpy 2 and Py 2 (Sample 6122-Cat, Ace deposit). B: U 2 -Hem 4 -Cl 4 -Cal 4 -Py 3 vein cutting
cataclasite rock and filled by tensional vein of Qtz 3 and Cal 3 (Sample 6122BV-Cat, Ace
deposit). C: Mineralized metasomatic granite in Gunnar: U 3 fills voids felt after Qtz 1
dissolution and is associated with Chl 5 , Src 3 , Hem 5 , Mnz 1 , Cal 5 and Ttn 2 (Sample GN-05,
Gunnar). D: Breccia with fragments of cataclasite rock in a Cal 8 -rich matrix. U 4 surrounds
breccia fragments and is disseminated in matrix associated with Chl 7 , Src 3 , and Hem 6 (Sample
B5812, Ace-Fay deposit). E: Mafic volcanic-type ±U 5 : hydro-breccia vein composed of crushed
Qtz 1 and Kfs 1 fragments and Cal 9 embedded in a Chl 8 -rich matrix. U 5 is associated with Hem 7 ,
Ap 1 , Src 4 , Ttn 3 , Mnz 2 , Py 6 , and Cpy 5 (Sample Cl-45, Cinch Lake deposit). F: Late mineralized
veins containing U 6 , Cal 10 , Chl 9 , Hem 8 . G: Late Cal 11 , Chl 10 and Qtz 5 veins (Sample 2202,
Martin Lake deposit). H: Late sulphide minerals composed of Gn 1 , Cpy 5 and Py 8 and Sp 1
(Sample B5800, Ace-Fay deposit). Ap: apatite, Cal: calcite, Chl: chlorite, Cpy: chalcopyrite,
