"The P2 reverse fault in the Athabasca Basin was a conduit for basinal fluids to enter the basement rocks below the regional unconformity and modify the rocks through fluid-rock interactions. Along the P2 fault, the basement rocks consist predominately of graphitic metapelite with quartzite and pegmatite. Immediately below the unconformity is an alteration profile consisting of a lower Green Zone with chlorite and illite, middle Red Zone dominated by hematite and kaolinite, and a discontinuous Bleached Zone of kaolin-group minerals and illite right at the unconformity. Preliminary data suggest that the alteration profile cannot be attributed solely to paleo-weathering but rather must include multiple fluid events from paleo-weathering through diagenetic to late hydrothermal fluids"--Abstract, page [3].
