Low bottom and ochre

Ocher potential areas are designated low-lying areas, part of which has been mapped for sulphur acidity (pyrite content). With regard to ochre, the low-lying areas are divided into the following classes:
Class I > 50% of the profiles contain highly acidified samples.
Class II 20-50% of the profiles contain highly acidified samples.
Class III <20% of profiles contain highly acidified samples.
Class IV no acidified samples.
Class V not classified.
