Mica flakes between crossed polarizers can be seen but quartz particles less so because of their lower birefringence. Consisting of silt-sized particles. Further subdivision is possible into fine, medium and coarse silt-sized material. It should be noted whether the grains are coated with clay or whether bare. Consisting of sand-size grains.
Further subdivision is possible as for silt above.
Teh class can be subdivided into silty clay where some silt grains are disposed throughout a clayey mass and clayey silt in which the silt fraction is dominant but more clay is present than just as coats. Depletion Pedofeatures are pedofeatures arising from the loss of components, other than textural ones, compared with the adjacent matrix. Its identification depends mainly on the depleted area being clearly contrasting compared with the adjacent matrix. Loss of a component from a particular area may not, in itself, produce a recognizabledepletion pedofeature unless the component has a clear morphological expression such as shape, internal fabric, or color. The description of depletion pedofeatures should include size , external morphology , internal fabric , contrast , abundance , variability , distribution and orientation .
