 Alteration zoning: Zoned alteration
developed in the sandstone column above unconformity type deposits commonly forms chimneys in cross section that surround, and extend upward for several hundred meters from the deposits through the Athabasca sandstone column.
These provide a much larger footprint that the deposits themselves, and an important tool in targeting drill holes. Two common end members of alteration are depicted at left. www.uex-corporation.com/s/AthabascaBasin.asp |
