Description
Summary:During geological engineering research for new building of the Novosibirsk state university a horizon of ground settlement classified by the standard analysis as sandy silt loam has been found. Genesis of this ground and its distribution remains obscure. Our study of grains size, electric and rockmagnetic properties of those materials shows that they are represented by inter-bedding of sandy layers of different grain size and horizons of fossil soils. The upper part of the section up to the depth of 0,8-1,0 m sufficiently differs from the lower part by abnormally high specific electric resistance, opposite character of correlation between grain size and rock- magnetic parameters that can be caused by a continuation of modern soil-forming processes. Our results recommend geological-geophysical studies of soils for the given territory with sampling interval in boreholes 0,5 m.
