Golden Arrow Mine
INTRODUCTION
The Gardnerville district is situated on the west slope of the Pine Nut Range in Central Douglas County and approximately 14 miles southeast of Minden and Gardnerville. It is adjoined on the west by Red Canyon district and on the southeast by the Wellington district. The Mount Siegel placer district lies to the north of Gardnerville district. GEOLOGY The principal country rocks are Tertiary andesite, which covers the summit areas of Gardnerville district and intrusive quartz monzonite which is, however, exposed by deep erosion in the southern and eastern portion of the district. Lake deposits and tuffs occur along the base of the west slope that are probably Pliocene in age. According to hill (1915) the augite-andesite is cut by nearly verticle, north-trending fractures at the Pine Nut fractures striking N.35 degrees E., and dipping steeply to the southeast. Gold is associated with altered and silicified wall rock in these fractured areas, with minor amounts of pyrite included in the mineralized zone. Mesozoic sediments composed of shale and lime stone, believed by Hill (1915) to be Triassic in age, have been metamorphosed at the Nevada Tungsten Mine where they have been converted to tactite with the introduction of scheelite. Organic deposits of recent origin have been known for many years, and a peet deposit was discovered in Carson Valley near Minden. These deposits probably were derived from the decomposition and subsequent burial of years of tule growth along an early channel of the Carson River. Possibly they were similar to the tule marsh that now exist along the River between Walley's Hot Springs and Genoa. Metal production from the Gardnerville district has been mainly gold, silver, and copper.
