4.4 Viper Property Geology

The Viper Property resides in a location of the Beardmore-Geraldton Greenstone Belt where the Central Meta-Volcanic Unit and the Southern Meta-Sedimentary Unit are strong folded together. This folding pattern closely resembles the same refolding that is found in the Hardrock Property area. The central meta-volcanic unit is comprised of massive and pillowed basalts and andesite with mid-ocean ridge basalt geochemical affinity, interlayered with thin sedimentary and tuffaceous beds. The central meta-volcanic unit differs from the southern meta-volcanic unit by thicker deposits of pyroclastic rocks and an abundance of large amygdules in the flow rocks, suggesting shallow-water or subaerial volcanism (Kresz and Zayachivsky 1991). The majority of the flow rocks are andesites and dacites of calc-alkaline affinity with trace and rare-earth element patterns suggesting deposition in an emergent volcanic arc above a subduction zone (Tomlinson et al. 1996). There are also numerous young diabase dykes running roughly north-south crosscutting all other rocks.  The southern meta-sedimentary unit is comprised of clastic and chemical sedimentary rocks. 

Polymictic conglomerate occurs as thin horizons (<5m) within a thick sequence of thinly to thickly bedded feldspathic sandstone interlayered with thinly bedded siltstone and argillite. Banded iron formation, a minor component of the unit, occurs as fine magnetite-rich laminae and jasper-hematite beds within 3-30m thick horizons interlayered with thinly bedded green argillite, siltstone and sandstone. In the middle of the folded southern meta-sedimentary unit there is a large felsic porphyry plug. The felsic porphyry body is folded and is only slightly younger than the surrounding clastic meta-sediments.
