<p><strong>Fine soil</strong> particle shape depends solely on the type of mineral. Quartz, lime and dolomite are normally cubical, whereas clay minerals are flat, and halloysites (phyllosilicates) are oblong.</p></li>
<li>
<p><strong>Coarse soil</strong> particle shape and roughness depend on the type of rock as well as the individual history of transportation and weathering. A longer transport duration results in rounded edges and smoothed out particles. Weathering can also influence the particle …</p></li></ul></div></div>

<p>The grain particle shape has an influence on the texture and isotropy of the soil, as well as on the structural characteristics of the subsoil, such as the frictional resistance, shear strength, water permeability, compactness- and displacement capability [Soos96] [Trian00].</p><p>(Image: Particle shape - well rounded) (Image: Particle shape - Rounded) (Image: Particle shape - Sub rounded) (Image: Particle shape - Angular) (Image: Particle shape - Very …</p>
