Alteration

  • (Local) All Ore Bodies In The Area Are Surrounded By Light Brown To Yellowish Brown Alteration Halos Which Cut Across The Normal Purple And Gray Beds Of Host Rock Types. These Halos Are Characterized By A High Content Of Jarosite And Hydrous Iron Oxides, Seriticization Of Feldspar, And An Increase In Trace Amounts Of Molybdenum Near The Ore.

Ore body information

  • General form LENS/PODS
    Length 182.88M
    Width 30.48M

Controls for ore emplacement

  • Ore Fills Intraformational Channels And Scours Within Upper 30 Ft. Of Shinarump And Lower 60 Ft. Of Petrified Forest Members Of The Triassic Chinle Formation. Ore Tends To Occur In Depressions Along Channels, And Changes In Channel Direction, Favoring More Carbinaceous Layers.

Comments on the geologic information

  • ABUNDANT CARBONIZED PLANT REMAINS. MONTMORILLONITE CLAY DERIVED FROM VOLCANIC ASH.

Economic information about the deposit and operations
