Description of soil
The description of soil includes the level of detail of the description and whether or not the samples on which the description is based are or aren't of high quality. Moreover the described material, the description procedure and the description location are of high importance. These are all discussed below.
Described material
The borehole profile can only contain layers that are described as soil or antropogenic material.
Quality of the soil description
The purpose of this description is to confirm if the layering remained intact during transporting the soil out of the borehole called undisturbed sampling.
Geological standard: disturbed
The soil was described according to the requirements in SBB6:2020 for a standard geological description of disturbed drill samples.
Geological standard: undisturbed
The soil was described according to the requirements in SBB6:2020 for a standard geological description of undisturbed drill samples.
Geological extended: disturbed
The soil was described according to the requirements in SBB6:2020 for a comprehensive geological description of disturbed drill samples.
Geological extended: undisturbed
The soil was described according to the requirements in SBB6:2020 for a comprehensive geological description of undisturbed drill samples.
Description location
In this category the location where the description of the soil took place are listed.
Laboratory
The samples were described in a description room.
Field
The samples were described in the field immediately after sample collection.
Field laboratory
The samples were described in a container on board of a ship or a similar place, immediately after sample collection.
Description procedure
The description of soil must be done via the GDN_SBB6v2020 which is the Standard Drill description method 6 version 2020. This is a procedure for the description of soil that is established by the geological service of the Netherlands.
