The Astromaterials Data Repository (AstroRepo) is a curated file repository for astromaterials sample data.

AstroRepo FAQ

AstroRepo is a domain repository which primarily serves the cosmochemistry community. We welcome contributions of a broad range of extraterrestrial data, including but not limited to, compositional data for samples of lunar rocks, meteorites, minerals, melt and fluid inclusions, and more; geochemical synthesis datasets; geochronological data; petrographic descriptions of samples; kinetic data from geochemical and petrological experiments. Please send us a message at to check if your data is best represented in AstroRepo. We are not able to accommodate software, code or figures at this time.

Allowed file extensions are can be found at this link.

Tabular data should be in an AstroRepo template, but must at the very least be in a .csv, .txt, or .xlsx file. We strongly recommend the use of the AstroRepo data template, which expedites dataset publication. Data which does not meet the AstroRepo Data Submission Guidelines takes longer to process or may be rejected.

You will receive your dataset DOI only after your files and submission has been reviewed and accepted. Keep in mind that this entire process can take up to two weeks. Please try to submit your data ahead of when your publisher requests it.

Yes! Your data can be embargoed for up to two years from your submission date. There will be a public landing page that points to it, but it will not be available until the release date you chose.

Yes! You can let us know the status of your publication (in prep/submitted/in review/accepted) and once your paper is accepted notify us to update the final details of the citation at

Method codes identify the [Technique]-[Instrument]-[Laboratory] trio.

If you have multiple parameters analyzed on the same machine using the same technique, in the same lab, both parameters will have the same method number (code).

Example: Sr and Nd measured using VG Sector 54 TIMS at the University of Columbia would have method code 1, but Sr and Nd measured on Thermo Fisher ICP-MS at the University of Columbia would both have method code 2.

Yes! Please make sure that every data point is properly cited and have a full reference list that accompanies the data.

How to Cite AstroRepo

Cite the dataset with its dataset DOI in the References section of your publication.

The citation should be formatted as follows:

  • Creator(s) (Publication Year): Title. Publisher. Identifier. Data Accessed.

For example:

  • Torcivia, M. A., Neal, C. R., 2022. Ferroan Anorthosite 60025 Major Element Analysis of Pyroxene and Olivine, Version 1.0. Interdisciplinary Earth Data Alliance (IEDA). Accessed 2022-01-27.

Data Rescue

A focus of AstroMat’s activities is the rescue of data that are in danger of being lost because they are not accessible and curated in a sustainable manner. Data rescue efforts are intended to ensure that valuable legacy data sets that are in danger of being lost due to impending retirement of the data owner or degradation of the original data source are preserved and made accessible to the community for re-use by inclusion in the Astromaterials Data System.

Our team can advise and assist researchers that have unpublished data for inclusion in AstroRepo and AstroDB. Contact us at
