    Abstract : Sulphide soils in Sweden are mainly found along the northeast coastline. These soils area characterized by their fine grain size, low shear strength and black, or grey, color. These soils are also found further south, in the Sundsvall area in Västernorrland, but have slightly lower sulphide content there. READ MORE

  4. 3. Evaluation of cone factors for CPT-evaluation in CONRAD of sulphide- bearing soil in Mälardalen
