Replication Data for: Blaubeuren, Cloppenburg, and Machtenstein—Three recently recognized H-group chondrite finds in Germany with distinct terrestrial ages and weathering effects

Key points: Three meteorites (Blaubeuren, Cloppenburg, and Machtenstein) found in Germany were recently identified as H-group ordinary chondrites. Two of the meteorites had been previously recovered but were only identified as meteorites after further analysis. The study aims to fully characterize these meteorites based on their mineral composition, primarily olivine and * low-Ca pyroxene. Blaubeuren and Cloppenburg have a visible brecciated texture, common in chondrites, while Machtenstein’s texture is less apparent. Shock levels were classified as S2 for Blaubeuren and Machtenstein and S3 for Cloppenburg.Weathering has significantly impacted all three meteorites, eroding their fusion crust and metal content.* Oxygen isotope compositions align with other H chondrites, though Cloppenburg shows disturbance from terrestrial weathering.Cloppenburg contains vivianite, a rare hydrated iron phosphate mineral, indicating weathering in a wet environment.Terrestrial ages for Blaubeuren (~9.2 ka), Cloppenburg (~5.4 ka), and Machtenstein (~1.8 ka) show similarity to meteorites from wet environments. Overall, metal elements such as Fe, Co, and Ni have been altered, except for Co and Ni in Machtenstein, likely due to its shorter terrestrial age.
