Comments on the geologic information

  • Geologic Description = This occurrence is in the east part of the Windy Creek stock, a mid-Cretaceous composite pluton of quartz monzonite, monzonite, syenite and some melanite-bearing nepheline syenite (Miller and others, 1971; 1972). Latite and greenish quartz porphyry, both commonly pyritiferous, locally crosscut the alkalic phases of the Windy Creek stock. Two samples of pyritiferous quartz monzonite from this ridge crest have weakly anomalous lead values (150 ppm) and one contains 20 ppm Sn. A pyritiferous aphanitic dike from this ridge contains 150 ppm Cu, 700 ppm Pb, 700 ppm Zn, 15 ppm Sn, and 1 ppm Ag (Miller and others, 1971, Table 2). Molybdenum was detected at low levels in the aphanitic dike but was below detection in the other two samples. This occurrence primarily serves to illustrate that late, cross-cutting phases of the Windy Creek stock are mineralized compared to earlier, pyrite-bearing phases.
  • Age = Mid-Cretaceous; the Windy Creek stock is inferred to be mid-Cretaceous based on similarities to the Granite Mountain stock to the east in the Candle quadrangle (Miller and others, 1971).
