Methods of the determination of the mechanical composition, the water capacity, the hygroscopy and especially the mineral composition were described. Methods were mainly optical.
A detailed description was made of all minerals observed. These descriptions could be compared with the description of the properties of the minerals in the samples, which properties are given in the appendix,
No conclusions were drawn on the origin, weathering and agricultural evaluation, because information was not sufficient to allow such conclusions. Many micrographs show the various minerals.
