Stratigraphic Nomenclature news and updates
Below you will find news and updates concerning the Stratigraphic Nomenclature of the Netherlands.
-
A problem has been detected with the display of stratotypes. The borehole name is not displayed, which also prevents clicking through to the corresponding PDF. This is a technical problem that will be fixed as soon as possible.

The revamped Stratigraphic Nomenclature of the Netherlands was published in 2020. This new version came with new distribution maps for many of the stratigraphic units contained in the Stratigraphic Nomenclature. Those distribution maps were added to get a general understanding of the distribution of a unit. Since the release of the revamped website, many people have asked for the ArcGIS shapefiles of the polygons in the distribution maps. It even appears that for many stratigraphic units, the maps published here are the only ones available.
Therefore the Geological Survey of the Netherlands, part of TNO, has decided to release the shapefiles of the polygons used for the distribution maps. The files are made available as ZIP-files per stratigraphic group, and can be downloaded here.

Core photo's have been added to the description of the Volpriehausen Formation (RBMV). The core was taken in geothermal borehole NLW-GT-01. TNO made it possible that the core was slabbed and photographed.

The Royal Dutch Society for Earth Sciences (KNGMG) published a PDF-version of its 'Geological Nomenclature' by Visser in 1980. The first edition of this nomenclature dates from 1929. The nomenclature was a great success and contained about 4000 terms. The main language was Dutch with a translation into English, French and German. In 1959, the second edition was published with the main reason that many new terms and geological insights were introduced in the intervening period. The main language was changed to English with a translation into Dutch, French and German. The number of terms increased to 5500. In 1980 the third edition was published. The main language was not changed, but a translation into Spanish was added. The number of terms increased to over 10,000.

On Monday 8 June the revamped Stratigraphic Nomenclature of the Netherlands will appear online. Some highlights: integration of the former ‘shallow’ and a ‘deep’ versions, fully bilingual, more concise text, new distribution maps and addition of core photographs. From now on the online Stratigraphic Nomenclature is the up-to-date source for stratigraphic information from the Dutch subsurface.
