Martian meteorite ejection ages compilation

This dataset is a compilation of cosmic ray exposure (CRE) ages and terrestrial ages of martian meteorites (shergottites, nakhlites, chassignites, orthopyroxenite, and regolith breccia) in published literature as of July 2023. Igneous crystallization ages are listed where available; the dataset only lists meteorites with ejection age (CRE age with or without terrestrial age) data. The compilation is an update of an earlier version partially included in Udry et al. (2020). For meteorites with multiple reported CRE ages and terrestrial ages (the latter where available), a preferred age is given either based on an earlier compilation (in the 'Compilation Reference' field) or is calculated as the arithmetic average of multiple reported ages (in the 'Data Reference' field; for CRE ages only). In the latter case, the 'Compilation Reference' field is marked with 'this compilation'. Paired stones are combined under one entry. Note that this compilation is not an exhaustive listing of all CRE age, terrestrial age, or igneous crystallization age data reported for martian meteorites. This dataset contains two files: A spreadsheet (.xlsx) containing meteorite names, types, ejection age groups, CRE ages, terrestrial ages, ejection ages, data references, compilation references, list of nuclides measured, igneous crystallization ages, data references, and compilation references. A document (.docx) containing a list of references cited in this compilation. References C. D. K. Herd et al., The source craters of martian meteorites: insights from a multi-method approach. Lunar.
