N2 - The carbonate-hosted Buick mine Pb-Zn-Cu deposit in the Viburnum Trend, southeast Missouri, is immediately overlain by the shale of the Davis Formation. The mineralogy of clay and clay-sized minerals and selected geochemical aspects of this shale were examined along a traverse normal to the Viburnum trend. The shale consists of illite, illite-smectite, monoclinic K feldspar, and quartz; minor minerals include chlorite, dolomite, calcite, pyrite, and gypsum. Alterations to shale of the Davis Formation within the Viburnum Trend include lowering of the illite crystallinity index, changes in the amount of K in wholerock shale samples, and the presence of gypsum in the <2-μm fraction. -from Authors
