Ore controlSome Control Possible By Fracturing At Slight Angle To Channel. 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.
