“…Most authors found only a few basic chemical types (4-5) of saline waters (brine type) with certain combinations of Na, Mg, Cl, SO 4 , HCO 3 and CO 3 (e.g., Eugster and Hardie, 1978;Williams, 1998;Warren, 2006). Hammer (1986) divided them into six types (Na-HCO 3 , NaCl, Ca-HCO 3 , Mg-HCO 3 , Na-SO 4 , Mg-SO 4 ) based on the 25 equivalence per cent (e%) dominance of the cations and anions, while according to multiple ion dominances, many subtypes of saline waters (at least 20-25) were described all over the world.…”

-We investigated the chemical characteristics of the astatic soda pans in the Carpathian Basin based on comprehensive new and archive data. Analysed parameters were salinity and ionic composition. The most frequent type of soda waters was the basic alkaline type (Na-HCO 3 ) that represented more than half of the natural soda pans. Besides 11 subtypes occurred. The second and third most frequent types were the chloride (13%) and sulphate subtypes (11%), with the secondary dominance of these anions. The other subtypes meant < 4% of the pans. Magnesium sometimes occurred as a secondary dominant cation beside sodium. Until now, this subtype of soda waters has not been published in any part of the world, because of the general rule of soda lake formation (depending on low levels of magnesium and calcium). We found a regionally constant correction factor [Salinity (mg.L x1 ) = 0.8 r El.Cond. (mS.cm x1 )] for confidentially estimating salinity from electrical conductivity in these habitats. Salinity varied between sub-(0.5-3 g.L x1 ) and hypersaline (> 50 g.L x1 ) ranges, with its mean value (y 4 g.L x1 ) in the hyposaline range (3-20 g.L x1 ). The basic alkaline type had random geographical distribution, while the other subtypes were restricted to certain regions of the Basin. The high number of subtypes reflects the high chemical diversity of alkaline soda pans in the relatively small territory of the Carpathian Basin.

“…Eutrophication and lake shallowing may have resulted from periods of high productivity, as indicated by charophyte abundance and the alkalinity index. Based on the Eugster and Hardie (1978) Humphrey and Ferring (1994) found a 14000-year stable-isotope record showing that, for the period between 2000 and 1000 years B.P., conditions were drier than they are today. The stableisotope record obtained in this study agrees with that of Humphrey and Ferring (1994).…”

In combination, microinvertebrates, calcareous algae (Charophyta), and the stable isotopes from ostracodes and gyrogonites (the calcareous remains of charophytes) are a powerful tool for reconstructing paleoclimates. This study compares the paleoenvironmental signatures of land and aquatic mollusks, ostracodes, and charophytes with stable-isotope (δ 18 O and Resumen En combinación, los microinvertebrados, algas calcáreas (Charophyta), e isótopos estables de ostrácodos y girogonitos (los restos calcáreos de carófitas) constituyen una herramienta muy poderosa para reconstruir paleoclimas.

“…We conclude therefore, that ash deposition was likely the direct or indirect causal factor of the Kilpoola lake salinity event. The geology and composition of catchment soils have a tremendous influence on the chemical composition and salinity of closed basin brines (Eugster and Hardie, 1978;Renaut, 1990;Topping and Scudder, 1977). Deposition of a fresh (unweathered) tephra over the weathered, pre-existing soils would be expected to influence the ionic strength and composition of Kilpoola Lakes water.…”

AbstractSalinity fluctuations in lakes of semi-arid regions have been recognised as indicators of paleoclimatic change and have provided a valuable line of evidence in paleoclimatic reconstruction. However, factors other than climate, including sedimentologic events, may also affect salinity. At Kilpoola Lake, early postglacial freshwater chironomids (Microtendipes,Sergentia, andHeterotrissocladius) occur in the basal sediments and yield a chironomid-inferred salinity of <0.03 g/l. Higher salinities, ranging from 1.0 to 3.5 g/l, withCricotopus/OrthocladiusandTanypus(chironomids typical of saline environments) follow and, persist for most of the remainder of the Holocene. An inferred 450% salinity increase (from 1.6 to 7.3 g/l) occurred in the sediment above the Mount Mazama tephra, followed by a return to the pre-Mount Mazama salinity. The early Holocene pollen spectra are typical of open steppe, but the post-MazamaArtemisiapollen percentages are exceptionally high and are associated with silty clays. Pollen spectra following thisArtemisiapeak represent steppe communities and are consistent with regional trends. We suggest that the changes in chironomid communities and vegetation after deposition of the Mazama ash do not reflect a rapid shift to warmer or drier climate and evaporation, but rather an increased ionic concentration due to solutes derived from the freshly deposited tephra and perhaps in- washed silts and clays.
