| Abstract: | Ba, Ca, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Na, Ni, Pb and Zn were studied in cores of peat from two major vegetational areas of the Okefenokee Swamp, Georgia; both total peat and organic fractions were investigated. Except for Hg and Pb, metal concentrations were either higher or equal to Clarke values. The sandy bedrock is not an important contributor to metal concentrations found in peat. Levels of metals in a given peat sample were related to plant materials which gave rise to the peat; it does not appear that vegetational environment plays a critical role in determining trace metal distribution, but does play a role in determining the amount of humic or pre-vitrinitic constituents that eventually are found in coal. |
