Tiny brownish-purple zirconcrystals are found with feldspars, actinolite, chlorite and biotite in a metarhyolite within the Quinnesec Formation in an outcrop on the south side of a town road in the center of sec.
Zircon forms tiny crystals in the Dunbar Gneiss, such as is exposed on the east side of County U in the center of the W 1/2 sec.
SAUK COUNTY: Tiny white, pink and yellow zircon grains are common in heavy mineral concentrates the Precambrian rhyolite, the Baraboo Quartzite and overlying Cambrian sediments near Baraboo (Becker, 1931).
Zircon has long played a supporting role to more well-known gemstones, often stepping in as an understudy when they were unavailable.
Zircon occurs in a wide range of colours, but for many years the most popular was the colourless variety, which looks more like diamond than any other natural stone because of its brilliance and dispersion.
Zircon is one of the heaviest gemstones, which means that it will look smaller than other varieties of the same weight.
