4. Pedofeatures




They are pedofeatures that occur in the matrix, but adjacent to natural surfaces (generally voids).

They can be the impregnative, depletion or fabric type.

The types that can be distinguished are the same as in the coatings.

They are often from:

accumulation of carbonates


accumulation of Fe compounds


accumulation of Mn compounds


depletion of Fe/Mn compounds
