3. Groundmass
This deals with analysing the distribution patterns between the different soil components, whether they are individual, aggregate or complex domain grains. It expresses the distribution of the individual fabric units with regard to the smallest fabric units and associated voids (c/f = coarse / fine). The limit between the large and small units is arbitrary and depends on the particular characteristics in every sample (10 microns usually give good results).
The following types can be distinguished:
All those included between these types can be present.
