Where to Find Dolomite in Missouri

Missouri dolomite is the host rock of the state's lead-zinc ores and a famous specimen mineral in its own right. The Sweetwater mine in Reynolds County produces ferroan dolomite as pink-to-tan curved rhombs ("saddle dolomite") up to several centimeters, often blanketing massive galena and calcite. Brushy Creek and Buick add white and gray dolomite on the same dump material. Tri-State chat piles around Joplin carry pink dolomite crusts with marcasite and sphalerite. The pink, curved-face dolomite from Sweetwater is among the most distinctive Missouri specimens and is widely traded in the mineral market.
