Imperfections of these thin sections
Obtaining thin sections from such a heterogeneous material (the soil), is a very complex and arduos task; thus, microscopic preparations usually include some imperfections, just as in the examples below, that must be recognized so that they are not confused with soil features.

The anisotropy of the inclusion resin in this thin section is unusually intense, making difficult the recognition of some pores, thus, I have touched up the images in some cases.

NOTE. The hydromorphy of this profile is not intense enough for appearing neither in the horizon nor the soil denominations (it is only visible using the microscope, not in the field).

This soil was studied by Fernando Santos Francés in his PhD Thesis "Estudio geológico y edafológico del sector Montiel-Alcaraz-Bienservida (Ciudad Real-Albacete)"
