“…7A, F). Similar precipitates form today in local environments of extreme oversaturation, for example, calcitic precipitates formed in leachate pipe systems in Florida (Maliva et al, 2000). More continuous surfaces show a granular texture, with relatively abundant 1-5 μm pyrite crystals; these are interpreted as exposure surfaces that underwent micritization prior to silica emplacement.…”

“…The abundance of microbial remnants at spherulite centers suggests that microbes are involved in aragonite precipitation by acting as nucleation sites. Spherulites found in hot water travertine crusts, composed of radiating aragonite needles around hollow centers, have been suggested as being microbially nucleated (Guo & Riding, 1992), and sulfate-reducing bacteria have been implicated as catalysts for mineral nucle-ation in the formation of calcite stromatolites and pisoids discovered in a landfill leachate collection system (Maliva et al, 2000). Furthermore, Braissant et al (2003) were able to form spherulites similar to those found in natural environments using extracellular polysaccharidic media; demonstrating the influence of bacterial outer structure composition on the morphology and mineralogy of bacterially induced calcium carbonate.…”

Microbialites were discovered in an open pit pond at an abandoned asbestos mine near Clinton Creek, Yukon, Canada. These microbialites are extremely young and presumably began forming soon after the mine closed in 1978. Detailed characterization of the periphyton and microbialites using light and scanning electron microscopy was coupled with mineralogical and isotopic analyses to investigate the mechanisms by which these microbialites formed. The microbialites are columnar in form (cm scale), have an internal spherulitic fabric (mm scale), and are mostly made of aragonite, which is supersaturated in the subsaline pond water. Initial precipitation is seen as acicular aragonite crystals nucleating onto microbial biomass and detrital particles. Continued precipitation entombs benthic diatoms (e.g. Brachysira vitrea), filamentous algae (e.g. Oedogonium sp.), dinoflagellates, and cyanobacteria. The presence of phototrophs at spherulite centers strongly suggests that these microbes play an important initial role in aragonite precipitation. Substantial growth of individual spherulites occurs abiotically through periodic precipitation of aragonite that forms concentric laminations around spherulite centers while pauses in spherulite growth allow for colonization by microbes. Aragonite associated with biomass (δ(13)C = -4.6‰ VPDB) showed a (13)C-enrichment of 0.8‰ relative to aragonite exhibiting no biomass (δ(13)C = -5.4‰ VPDB), which suggests a modest removal of isotopically light dissolved inorganic carbon by phototrophs. The combination of a low sedimentation rate, high calcification rate, and low microbial growth rate appears to result in the formation of these microbialites. The formation of microbialites at an historic mine site demonstrates that an anthropogenically constructed environment can foster microbial carbonate formation.

“…Calcite precipitating from landfill leachates was found to be an important carrier for trace elements, such as heavy metals and metalloids, playing thus a key role in their solid speciation and their potential environmental impact (Ettler et al 2006a, b). In landfill leachate collection systems, calcite precipitation is often mediated by biological activity (Maliva et al 2000). However, in trace element determination, EPMA often fails due to the low concentrations of the trace elements in calcite (Maliva et al 2000).…”

However, in trace element determination, EPMA often fails due to the low concentrations of the trace elements in calcite (Maliva et al 2000). If calcite precipitates in very significant amounts in leachate collection tubes or settling basins, trace element determination can be readily performed by conventional solution ICP-MS.…”

We report new data on the trace element concentrations of Mg, Cr, Mn, Co, Ni, Cu, Zn, Sr, Cd, Ba, La, Ce, Nd, Pb and U in USGS carbonate reference materials (MACS‐1 and MACS‐2) and compare solution ICP‐MS and LA‐ICP‐MS trace element determinations on landfill calcites using calibration to different reference materials (MACS‐1 and MACS‐2 carbonate and NIST SRM 612 glass). Very good agreement (differences below 10% relative) was found between laser ablation and solution ICP‐MS data for MACS‐1 with higher concentrations of trace elements (values between 100 and 150 μg g−1), with the exception of Cu and Zn. Similarly good agreement was found for MACS‐2 with lower trace element concentrations (units to tens of μg g−1), with the exception of Cr, Co and Zn. The MACS‐1 reference material for calibration of LA‐ICP‐MS was found to be extremely useful for in situ determination of trace elements in real‐world carbonate samples (landfill calcites), especially those present in calcite in higher concentrations (Mn, Sr, Ba; < 5% RSD). Less accurate determinations were generally obtained for trace elements present at low concentrations (∼ units of μg g−1). In addition, good agreement was observed between the instrument calibration to MACS and NIST SRM 612 glass for in situ measurements of trace elements in landfill calcites K‐2, K‐3 and K‐4 (differences below 15% relative for most elements). Thus, the application of MACS carbonate reference materials is promising and points to the need for the development of new carbonate reference materials for laser ablation ICP‐MS.
