Research on potentially toxic elements chromium and nickel and laboratory testing of their concentrations was carried out in the wider area of Maglaj, with the aim to detect and determine their quantities, which gave basis for discussion about origins of these pollutants in soil. Field and laboratory observations included 45 soil samples, taken by the network, which is dictated by geomorphological conditions. The most frequently sampled type of soil are fluvisol and humofluvisol. Concentration of chromium (Cr) and nickel (Ni) are obtained by the most sophisticated laboratory method (ICP-MS), with a highly sensitive detection threshold (0.1 to 10,000 ppm).Evaluation of test results showed that concentrations of Cr (max. 954 ppm, min 154 ppm, average 457.5 pmm) and Ni (max 504.5 ppm, min 103.5 ppm; average 275.57 pmm) are significantly increased compared to the concentrations prescribed in the Regulations on determination of allowed amounts of harmful and hazardous substances in soil (Cr max = 100 ppm and Ni max = 50 ppm). Considering geological settings of surrounding area (the dominant presence of igneous ultramafic and mafic rocks) it can be concluded that high concentrations of Cr and Ni have geogenic origins, what is mean that they originate from source rocks from which they are separated through the long-term decomposition and disintegration processes.

“…Previous studies have reported elevated concentrations of trace metals (particularly Ni,Cr 3+ and carcinogenic Cr 6+ ) in soils and waters associated with serpentinites (Margiotta et al, 2012;McClain and Maher, 2016;Morrison et al, 2015;Schreier, 1987;Schreier and Lavkulich, 2015). Uptake of these trace metals by Fe-hydroxide and clay minerals has been documented in serpentinites (Morrison et al, 2015), but the influence of hydrated Mgcarbonate minerals on trace metal mobility within ultramafic environments is relatively unexplored. This is a critical knowledge gap, given that hydrated Mg-carbonate minerals are commonly present in high abundances [up to 14.6 wt.…”

“…from negatively fractionated Cr(III) adsorbed to clay minerals (Condie and Wronkiewicz, 1990, and references therein; Garnier et al, 2013;Morrison et al, 2015). Here, we report positivley fractionated Cr isotope singals characteristic for an oxygenated environment and investigate the otherwise largely negativly fractionated Cr isotope signals of two cap dolostone sections pertaining to the Doushantuo Formation in regard to a possible overprint by (i) detrtital contamination and (ii), explore the influence of diagenetic alteration and post-depositional remobilization of (isotopically heavy) Cr.…”

Dilution of seawater with freshwater from slowly melting icebergs is indicated for the studied cap dolostones by typical seawater-like REE + Y patterns with generally superchondritic but less than modern marine Y/Ho ratios (Bau and Dulski, 1994;Lawrence and Kamber, 2006), by enhanced ΣREE contents and by a negative correlation of Y/Ho ratios with whole rock Al concentrations (Hohl et al, 2015).…”

Chromium isotope stratigraphy of Ediacaran cap dolostones, Doushantuo Formation, South China

2016

The Yangtze Platform in South China is considered a key site for studying Neoproterozoic ocean oxygenation. Comprehensive Cr concentration and isotopic signatures are presented from cap dolostones of the Doushantuo Formation from a deep water and a shallow marine carbonate section, that have previously been used to constrain the redox evolution of Ediacaran seawater in space and time employing major and trace element abundances as well as Sr-, O-and C-isotope compositions. The majority of the studied samples yield elevated Cr concentrations and negatively fractionated δ Sr signal close to Ediacaran seawater values with relatively high Sr and Cr concentrations, with decreased detrital contamination and with a pronounced negative Ce anomaly. They indicate either light pulses of enhanced oxidative weathering or, inferred from a few leastaltered samples, prevailing oxic conditions during cap dolostone deposition. The Cr isotopic composition of Ediacaran cap dolostones pertaining to the Doushantuo Formation reveals fine-scale fluctuations in postglacial detrital contamination and diagenesis balanced against a clear signal of oxidative weathering. Cr isotopes have the potential to further enhance our understanding of Neoproterozoic weathering regimes and past ocean oxygenation, however, before the Cr isotope system can be faithfully applied to delineate changes in redox conditions recorded in ancient marine carbonates, possible diagenetic alteration of the Cr signal as well as Cr contribution from detrital contamination need to be taken into consideration.
