IGSN-CNRS – échantillons publiés (production)

IGSN-CNRS is a registry of geoscience samples within the Solid Earth scope.
Every rock, sediment, mineral, synthetic or extraterrestrial sample registered there receives an IGSN (International Generic Sample Number): a unique identifier, used worldwide, that makes the sample findable and citable without ambiguity.

This dataset gathers every sample published in the registry, sub-samples included, so you can explore, map or cross-reference these collections without browsing the website one sample at a time.

• Where each sample comes from: coordinates, region, locality, collection date and method.
• What it is: nature, material, texture, age, dimensions, and any safety warning (radioactivity, asbestos, chemical risk).
• Who is behind it: collector, chief scientist, research programme, funders, and the laboratory and OSU that keep it today.
• How it is kept: packaging, storage conditions, and whether it still exists and can be accessed.
• How it connects: its parent samples, the sub-samples prepared from it (thin sections, powders...), and related publications or datasets.

• https://igsn.cnrs.fr/samples/<igsn> opens the public page of any sample from its igsn.
• Researchers can declare their own samples with a free account at https://igsn.cnrs.fr/.
• The dataset is refreshed on the 1st of each month, each refresh replacing the files in place so their links stay stable.

IGSN-CNRS was initiated by CNRS through INSU, is led by OSU OTELo and funded by GaiaData.

The README.txt resource documents every column of every file and how to read them.

This dataset is distributed under the CeCILL 2.1 license (https://cecill.info/licences/Licence_CeCILL_V2.1-en.html), the license of the registry's source code.
