The leaching and original content of calcium carbonate in till in northern Uppland, Sweden

Inferences About Radionuclide Mobility in Soils Based on the Solid/Liquid Partition Coefficients and Soil Properties

“…That process will continue and, in a few thousand years, will cause decreasing pH and K d values. An earlier study from the same region as Forsmark (Ingmar and Moreborg 1976) has shown that calcite leaches completely from the uppermost part of till that has been exposed to weathering for a few thousand years.…”

“…The till is characterised by calcium carbonate concentrations of 10-30% which is about 30 times higher than the Swedish reference data (Lundin et al, 2004;Tröj-bom and Söderbäck, 2006). Its origin are Palaeozoic limestone deposits at the bottom of the Baltic Sea northwards (Ingemar and Moreborg, 1976), transported to the area by the Pleistocene ice sheet. Also the Sr concentration is elevated (27-175 ppm;Tröjbom and Söderbäck, 2006), most likely as a result of Sr accumulation in the calcium carbonate.…”

Lime Limit Changes

“…Similarly, Simin (1984) reported an annual loss of 325 kg CaO per ha between 1963 and 1980 from the top soil in a gyttja clay. Ingmar & hloreborg (1976) studied the carbonate content in soils in the northeast part of Uppland in Sweden at different distances from the sea and at different altitudes. They determined the rate that lime has leached out of the soil since the last glacial period.…”
