dolomite may form as a hydrothermal replacement mineral and as such is especially abundant as a gangue mineral in the ore deposits of the upper mississippi valley zinc-lead district in southwestern wisconsin. ferroan dolomite appears in several of the state’s precambrian iron formations. finally dolomite locally occurs in the state in marbles.
the silver veins are restricted to the goodsprings dolomite. the veins are composed of a gangue of calcite-dolomite and quartz while the ore mineralization is reported to have occurred as pods and blebs of stromeyerite with minor azurite and malachite (hewett 1956 cited in sharp 1984 pg. 125 ).
