The Astromaterials Data Repository (AstroRepo), uses policies in compliance with the EarthChem Library. Below are the specifics for AstroRepo.

What to contribute

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.

You may contribute data in any format, but tabular data must be in .csv, .xls, .xlsx or .txt. We strongly recommend the use of data templates, which expedites dataset publication. Data which does not meet the AstroRepo Data Submission Guidelines takes longer to process or may be rejected.
