Abstract

Brief observations are made on mineral zoning in Arkansas, including the Hg area of Pike County and the Sb area of Sevier County. Sulfide distribution in the Bellah mine is such that galena is most abundant above the 115-ft. level and sphalerite and chalcopyrite, successively, most abundant below. The mineralized veins in W.-central Arkansas show zonal arrangement of metals from Hg down to Cu with the Ag zone absent. The possibility of lower zones of Au, As, and Sn may be inferred.
