| | Detachment-fault-related Mineralization |
 | | However, detachment-fault-related mineralization is not widely known, having been described but twice in widely circulated journals (Spencer and Welty, 1986; Roddy and others, 1988); most of the detailed studies have appeared as publications of the Arizona Geological Survey and the Arizona Geological Society. |
 | | }}-->The detachment fault and structurally higher normal faults locally host massive replacements, stockworks, and veins of iron and copper oxides with locally abundant sulfides, veins of barite and (or) fluorite, and veins of manganese oxides (Spencer and Welty, 1986; fig. |
 | | }}-->This mineralization is termed detachment fault related not simply because it is strongly controlled by detachment-fault structures, but also because it is apparently related to the formation of detachment faults themselves (Roddy and others, 1988). |
