The Quartz Creek pegmatite field is located 17 miles almost due east of Gunnison, in Gunnison County, north and south of the road connecting Parlin and Ohio City.The 1,803 mapped pegmatites are centrally located around the Black Wonder pegmatitic granite and cover an area of 26 square miles (Hanley, Heinrich, and Page 1950; Staatz and Trites 1955).The exposed pegmatites form an example of a zoned field where the pegmatites closest to its source pluton are geochemically less evolved with the most distal pegmatites being the most geochemically evolved.The minerals found in these pegmatites are among the most rare in Colorado.
