“…Best et al (1999) reported the presence of Ca-bearing birnessites in uncemented sediments also collected at the R2B site in May 1997. Bilinski et al (2002), and Lind and Hem (1993) also reported the presence of Ca-bearing birnessites (rancieite/takanelite) in cemented crusts collected near gaging station 09498400 (at Inspiration Dam) and at Setka Ranch. In all cases, these assignments were based on the presence of a basal plane reflection at ca 7.3-7.54 Å , which compares well to the $7.4 Å position of the (0 0 1) reflection observed in the desiccated samples of the present study.…”

“…These authors noted that Pinal Creek stream water at the R2B location plots across several Mn mineral stability fields, including birnessite, and pyrolusite. Lind and Hem (1993) reported that the <63 lm size fraction from recently formed crusts collected near Inspiration Dam contained a mixture of rancieite and takanelite. The average Mn oxidation state in the <75-lm size fraction was found to be 3.78 ± 0.04.…”

“…Major minerals identified in crusts and streambed sediments include quartz, feldspar, and magnetite (Lind and Hem, 1993;Best et al, 1999;Bilinski et al, 2002). Trace minerals include mica and chlorite (non-magnetic fraction), ilmenite, and hematite (magnetic fraction).…”

“…A more informed understanding of these important natural materials is required and must rest upon observations at field sites where biogenic Mn(II) oxidation has been clearly established as the dominant process. Remarkably few such studies have been performed (Lind and Hem, 1993;Best et al, 1999;Bilinski et al, 2002).…”

The microbial catalysis of Mn(II) oxidation is believed to be a dominant source of abundant sorption-and redox-active Mn oxides in marine, freshwater, and subsurface aquatic environments. In spite of their importance, environmental oxides of known biogenic origin have generally not been characterized in detail from a structural perspective. Hyporheic zone Mn oxide grain coatings at Pinal Creek, Arizona, a metals-contaminated stream, have been identified as being dominantly microbial in origin and are well studied from bulk chemistry and contaminant hydrology perspectives. This site thus presents an excellent opportunity to study the structures of terrestrial microbial Mn oxides in detail. XRD and EXAFS measurements performed in this study indicate that the hydrated Pinal Creek Mn oxide grain coatings are layer-type Mn oxides with dominantly hexagonal or pseudo-hexagonal layer symmetry. XRD and TEM measurements suggest the oxides to be nanoparticulate plates with average dimensions on the order of 11 nm thick Â 35 nm diameter, but with individual particles exhibiting thickness as small as a single layer and sheets as wide as 500 nm. The hydrated oxides exhibit a 10-Å basal-plane spacing and turbostratic disorder. EXAFS analyses suggest the oxides contain layer Mn(IV) site vacancy defects, and layer Mn(III) is inferred to be present, as deduced from Jahn-Teller distortion of the local structure. The physical geometry and structural details of the coatings suggest formation within microbial biofilms. The biogenic Mn oxides are stable with respect to transformation into thermodynamically more stable phases over a time scale of at least 5 months. The nanoparticulate layered structural motif, also observed in pure culture laboratory studies, appears to be characteristic of biogenic Mn oxides and may explain the common occurrence of this mineral habit in soils and sediments.

“…In various natural settings (Jenne, 1968;Carpenter et al, 1975;Robinson, 1981;Dillard et al, 1982;Lind and Hem, 1993) and in a series of laboratory experiments, many metals are closely associated with Mn oxyhydroxides, including: Zn (Balistrieri and Murray, 1986;Catts et al, 1986;Hem et al, 1987), Cu and Ni (Balistrieri et al, 1986;Hem et al, 1989), Cd (Hem et al, 1991), Pb (Catts et al, 1986); but also in deep-sea sediments (Cu, Ni, Pb and Zn) (Thomson et al, 1993), in sea water (Ni, Cu and V) (Shaw et al, 1990) and as coating on quartz (Manceau et al 2007). The importance of processes occurring at reaction sites on solid-phase surface in contact with Mn-bearing solutions has long been recognized, but these results are not observed here.…”

Partitioning of heavy metals in podzol soils contaminated by mine drainage waters, Dalarna, Sweden

Abstract. The discharge of acidic mine drainage waters onto a hillslope in Dalarna, central Sweden, has lead to the contamination of the podzol soils with Cu, Fe, Ni, Pb, Zn and sulfate. Samples from contaminated and reference soils have been collected for chemical and mineralogical analyses. Jarosite is identified by x-ray diffraction analysis as a precipitate in the upper horizons (A, E, B) of the contaminated soils, where the soil acidity (pHKcL ~ 2.6) promotes jarosite stability. The sequential chemical extraction of soil samples indicates that, in the reference A horizon, Cu, Pb, Ni and Zn are bound primarily to cation exchange sites and organic matter. In the A horizon of the contaminated soils closest to the rock dump, metal partitioning is dominated by the Fe oxide fractions, despite the high organic matter content; Pb is almost completely bound to crystalline Fe oxides, possibly adsorbed to Fe oxides or occuring in a jarosite solid solution. In the reference B and C horizons, Cu, Ni and Zn are primarily adsorbed/coprecipitated in the Fe oxide fractions, while Pb remains with a large fraction bound to organic matter. In the Fe-rich B horizon of the contaminated soils, the partitioning of the metals in cation exchange sites and to organic matter has greatly increased relative to the reference soils, resulting from the mobilization of organo-metal complexes down the profile.
