“…The last option must be considered for the Wiśniówka AMD waters due to the strong correlation of HREE with SO 4 2− ions; R 2 varies from 0.70 (Gd) to 0.87 (Lu) (Table 5). This REE fractionation may be coupled at least partly with multiple adsorption-desorption reactions and/or ion exchange between the water column and precipitates, colloids, or secondary minerals as reported by other authors (e.g., Johannesson and Lyons 1995; Gimeno Serrano et al 2000; Romero et al 2010). …”

“…Moreover, this convex-up REE profile suggests that MREE are either more easily leached from the host rocks or are more dissolved under the pH and redox conditions that prevail in AMD ponds and lakes (Leybourne et al 2000). The MREE enrichment in AMD waters has been reported worldwide by many authors (e.g., Johannesson and Zhou 1999; Gimeno Serrano et al 2000; Worrall and Pearson 2001; Zhao et al 2007; Pérez-López et al 2010; Grawunder et al 2014). However, the results derived from these studies suggest that other explanations of this phenomenon must be also considered, for example dissolution of primary minerals—uraninite (McLennan 1994), apatite (Hannigan and Sholkovitz 2001), and pyrite (e.g., Grawunder et al 2014)—and/or secondary minerals—Fe-oxyhydroxysulfates (Pérez-López et al 2010) or Fe-Mn-oxides and oxyhydroxides (Johannesson and Zhou 1999).…”

A detailed hydrogeochemical study was performed in the Wiśniówka mining area (south-central Poland). This covered three acid pit bodies, historic tailings acid ponds, acid pools, and additionally two neighboring rivers. All these acid mine drainage (AMD) waters are characterized by the pH in the range of 1.7 (pools) to 3.5 (tailings ponds). The most interesting is the Podwiśniówka acid pit lake that shows a very low pH (2.2–2.5) and very high concentrations of SO4 2− (2720–5460 mg/L), Fe (545–1140 mg/L), Al (86.2 mg/L), As (9603–24,883 μg/L), Co (1317–3458 μg/L), Cr (753–2047 μg/L), Cu (6307–18,879 μg/L), Ni (1168–3127 μg/L), and rare earth element (REE) (589–1341 μg/L). In addition, seeps that drain the Podwiśniówka mine tailings and partly aggregate piles form strong acid pools in the mining area. Along with these pools, in which As and REE contents reach 369,726 and 6288 μg/L, respectively, these waters are among the most distinctive As- and REE-rich AMD surface waters across the world. It is noteworthy that the Podwiśniówka acid pit lake and Wiśniówka Duża acid pit sump exhibit different element signatures and REE concentration patterns normalized to North American Composite Shale (NASC): the Podwiśniówka acid pit lake always shows a characteristic roof-shaped medium REE (MREE) profile with distinct enrichments in Gd, Eu, and Tb whereas the other one displays a step-shaped heavy REE (HREE) profile with positive Tb and Gd anomalies. The REE undergo fractionation during weathering and the subsequent leaching of dissolved and suspended fractions from rocks to acid water bodies where these and other elements are further fractionated by geochemical processes. This study shows that the individual REE have greater affinities for Mn, HREE for Fe and SO4 2−, and only La and Ce for Al. This specific water geochemistry has enabled us to (i) pinpoint the location of AMD “hot spots” originated from quartzite mining and processing operations conducted by current and previous mining companies, (ii) predict the directions and effects of future strip mining for quartzites in the Wiśniówka Duża and Podwiśniówka open pits, and (iii) evaluate the potential impact of mining and processing effluents on the quality of rivers.

“…Cu sulfide mineralization should be more abundant than Pb and Zn mineralization owing to the lower solubility of Cu relative to Pb and Zn in the presence of reduced sulfur (Pelch, Appold, Emsbo, & Bodnar, 2015). In addition, low pH, low-temperature waters are richer in REE than neutral and alkaline solutions (Serrano, Sanz, & Nordstrom, 2000). This suggests that the low fluid temperature and reducing environment may have led to the relatively positive Eu anomalies and low ΣREE in the Cu ores at the Huangshaping deposit.…”

The Huangshaping world‐class W–Mo–Cu–Pb–Zn deposit formed during Jurassic intra‐continental extension in the central Nanling region (South Hunan), South China. In order to assess the role of fluids in ore genesis and the origin of polymetallic mineralization, three types of mineralized porphyries (quartz porphyry, granophyre, and granite porphyry) were studied. The multi‐method approach included whole‐rock Sr–Nd isotopic geochemistry and determination of the trace element content and gaseous and aqueous composition of ore minerals from the three stages of intrusion and ore emplacement. Geochemical results show that the Sr–Nd isotopes in these altered porphyries were strongly affected by fluid metasomatism. The 87Sr/86Sr and 147Sm/144Nd ratios for the quartz porphyry and granophyre range from 0.72894 to 0.83093 and 0.1524 to 0.2080, respectively, whereas higher and considerably more variable ratios were determined for the granite porphyry (0.90396 to 1.51943 and 0.2391 to 0.2914). These observations imply that granite porphyry‐associated W–Mo mineralization underwent more intensive fluid–rock interaction. The relatively low REE concentrations and high abundances of CH4 and H2 in the Cu ores associated with the quartz porphyry unambiguously suggest a deep‐sourced magmatic fluid for the Cu mineralization. The high REE concentrations, pronounced negative Eu anomalies, M‐type tetrad effects, and high CO2, H2O, and Ca2+ contents of the W–Mo ores associated with the granite porphyry imply that the W–Mo polymetallic mineralization was formed in a relatively oxidizing, high‐temperature environment with strong metasomatism. In contrast, the slightly negative Eu anomalies, W‐type tetrad effects, low CH4, and high F− and Cl− concentrations of the Pb–Zn ores indicate involvement of a sediment‐derived basinal brine and reducing mineralization conditions. Collectively, a three‐stage genetic model is proposed for the Huangshaping polymetallic deposit. Corresponding to initiation, development, and cessation of Jurassic intra‐continental extension, magmatic water, metasomatized fluids, and basinal brines played key sequential roles in Cu, W–Mo, and Pb–Zn mineralization.

“…One of these examples is Gd, which has recently been recognized as an anthropogenic micropollutant (e.g., Knappe et al 2005; Bau et al 2006; Kulaksiz and Bau 2011). Of particular interest are acid mine drainage (AMD) streams, ponds, and lakes that give a direct insight into local and regional geologic sources highlighted by a number of REE profiles with LREE or HREE enrichments or MREE depletion (e.g., Johannesson and Lyons 1995; Gimeno et al 2000; Worrall and Pearson 2001; Bozau et al 2004; Verplanck et al 2004; Gammons et al 2005b). These studies have also showed that in low-temperature surface environments, REEs behave differently in relation to aqueous complexation, ion sorption–desorption, and mineral precipitation–dissolution or transformation.…”

The principal objective of the current study was to elucidate the potential influence of acid mine drainage (AMD) pond on neighboring farmer's wells in the Podwiśniówka area (south-central Poland), using North American Shale Composite (NASC)-normalized rare earth element (REE) concentration profiles. The well waters generally displayed a distinctly positive Eu anomaly similar to that of parent rocks and AMD sediment. In contrast, the AMD pit pond water exhibited the typical roof-shaped NASC-normalized REE concentration pattern with a strong positive Gd anomaly. The low pH (mean of 2.9) of this pond water is induced by oxidation of pyrite that occurs in quartz veins and rocks exposed in the abandoned Podwiśniówka quarry. The principal source of REEs in turn is a crandallite series of aluminum–phosphate–sulfate (APS) minerals (gorceixite with florencite and Ce-bearing goyazite) that prevail in most clayey shales. These data indicate that the REE contents of the AMD pit pond and well waters are linked to bedrock mineralogy and lithology, but not to pyrite mineralization. The diverse REE patterns of NASC-normalized REE concentrations of the AMD and well waters may suggest complex sorption and desorption processes that occur at the rock–water interface influenced by different pH, Eh, temperature, and other factors. This is evidenced by a presence of strong positive Ce anomaly in the rocks, a lack of Ce anomaly in the AMD water and sediment, and the dominant negative anomaly of this element in the well waters. Variations in correlation coefficients (r2) of REE concentrations between the rocks and the well waters may also result from a different contribution of quartzites, clayey shales, or tuffites to the REE signal of well waters as well as from mixing of shallow groundwater with infiltrating rainwater or meltwater with different REE profiles.
