Dear Laura,
Fully agree with Björn, Steffen, and Johanna.
The problem with these is not only that correlating them with the international stages requires geological knowledge and
time as Ralf pointed out, but also a lot of knowledge on history of science. In many cases different authors or schools have used these terms in different senses, stage XYZ of author A may, for example correlate to the Berriasian of the ICS, but the same stage
used by author B may correlate with the Valanginian. Therefore it is not simply a matter of doing the correlation once since a 1:1 correlation is rarely possible.
Additionally, many regional stages do not map to a single international stage, but may, for example include the younger
part of one ICS stage and the older part of the succeeding stage (the Badenian regional stage of the Paratethys is a good example).
Because of all these problems we use a separate field for regional and/or outdated term we use in our inventory database.
All the best
Andreas

Dear Laura,
I fully agree with Björn and Steffen. This is the only choice to apply this standard.
Best wishes

Hello Laura,
I am not 100% sure what for these categories are needed and why there is some constraint for the number of categories. But properly defined global chronostratigraphic units are the only choice and I would also go for a hierarchical solution with codes for e.g. the Mesozoic unspecified and then lower in the hierarchy toward the periods. The latest international standard can be found here: http://stratigraphy.org/index.php/ics-chart-timescale
Kind regards,
Björn

Subject: [CETAF_ESG] Advice need: about how earth science collections defined stratigraphically in institutions.
Dear colleagues,
I am writing to ask for some advice on how I should define the stratigraphic levels for the SYNTHESYS+ Collections Digitisation Dashboard. I have attached an excel sheet with classification of Stratigraphy from the ICEDIG project (sheet 1 in black ink) – I have added some categories in red – but I think there are too many to be filled in. Could Precambrian material be lumped together?
I would like to ask do we need that many categories really? – based on how earth science collections are categorised in institutions.
Do you have any insight into how Earth Science collections are classified?
I need to add a category for unknown.
In sheet two, CSIC Madrid has given an alternative classification.
I would be grateful for any feedback before the end of this week.
Best wishes
Laura
