Figure 5. Representative SEM images and EDS pattern from the syenite rock (a-b) and horizons (c-e : saprolite, f : horizon B, g-h horizon Ah). (a) syenite showing inclusion of uraninite in zircon. (b) U-monazite surrounding apatite in syenite. (c) Uranothorite and U-monazite on chlorite (d) microcrystal of uraninite in zircon inclusion. (e) Apatite trapping subangular U-florencite minerals. (f) Uranothorite on chlorite mineral. (g) SEM image of kaolinite. (h) SEM image of iron oxide trapped in kaolinite Abbreviations translate as follows, Zr : zircon, Ch : chlorite, Ab : albite, U-florencite, Ka : kaolinite, Ep : epidote, An : allanite, Ap: apatite, Ver: vermiculite, Ur: uraninite, U-Mz: U-monazite
