摘要

A concentration of ore bodies occurs in a belt across the Lukachukai Mountains. The ore belt conforms to a facies of lenticular sandstone and mudstone which provided sufficient permeable sandstone for the pas-sage of ore solutions and sufficient impermeable mudstone to canalize the flow of solutions into particular sandstone beds. An unusual concentration of carbon served as a precipitation agent. Lateral changes in permeability of the sandstone beds, related to the old stream systems, influenced the movement of mineralizing solutions. The moving solutions apparently bleached red sandstones to gray or to limonitic brown.nHapping of drill core data shows that (1) ore bodies ore elongate parallel to sedimentation, (2) ore bodies tend to occur along the flanks of sandstone channels which are bounded laterally by zones of "flood-plain" lithology, (3) ore foodies often occur in groups, (4) ore bodiss tend to "build up" against permeability barriers.
