Differences in silica release from soils of two Scottish associations as assessed by trimethylsilylation

摘要: Abstract The amounts of monomeric silica released on trimethylsilylation a range Soil Groups the Darleith Association, developed glacial till derived from Carboniferous age lavas basic and intermediate composition, is significantly higher than corresponding Lauder Devonian conglomerates sandstone. Monoremic release values for leached soils within an association are, in general, those gley soils. For all soil profiles eluvial horizon smallest amount with maximum being released, most instances, illuvial horizon. Ferromagnesian minerals crystalline clay minerals, particular vermiculite chlorite Association soils, under acid conditions. both principal source monosilicic thought to be aluminosilica gel low Si:A1 ratio.
