The Orderville Gulch mining district is in extreme western Kane County. The district is a minor U-V producer. The district shipped a few hundred tons of low-grade U-V ore to the Marysvale purchasing depot of the Atomic Energy Commission in the 1950s. Total district metal production at modern metal prices is estimated at $28,000. This production seems to have come primarily from the Lynn mine (Beroni and others, 1953).
The Orderville Gulch district is geologically situated on the Markagunt Plateau in the transition zone from the Basin and Range Province on the west to the Colorado Plateau on the east. The rocks of the district are nearly flat-lying Jurassic- and Cretaceous- age strata, dipping just 5° to the northeast. The mineralization is near the contact of the cliff-forming Dakota Formation and the very top of the Winsor Member of the Carmel Formation–Entrada Sandstone (USGS Model 30c). Mineralization is associated with carbonaceous clay, carbonized wood fragments, petrified logs, and Fe oxide concretions. The recognized ore minerals include carnotite, tyuyamunite, torbernite, and autunite-bearing clay. In addition to U and V, geochemical work suggests the mineralization may be enriched in As and Mo (Beroni and others, 1953; Doelling and others, 1989).
