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. ## What you will find - **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. ## Going further - `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. ## License 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. | https://www.data.gouv.fr/datasets/igsn-cnrs-echantillons-publies-production | Observatoire Terre Environnement de Lorraine (OSU OTELo) | http://www.opendefinition.org/licenses/cc-by-sa | 2026-11-03T15:35:21.734000 | 2026-11-03T19:02:04.134000 | ["open-science", "rock", "sample", "sediments"] | [] | https://www.data.gouv.fr/datasets/6ae9ff392e0e9701b8c0956e | 6ae9ff392e0e9701b8c0956e |
