The deviation seems to be caused by addition of varying amounts of terrestrial water in the case of carbonate. In the case of maskelynite, H is heterogeneously distributed and the deviation in <jats:italic>δD</jats:italic> values seems to be due to mixing of this indigenous heavy H with isotopically normal H present in the SIMS chamber. The indigenous <jats:italic>δD</jats:italic> value in ALH 84001 seems to be ∼2000%‰. Carbonate rather than maskelynite seems to be the main carrier of H in ALH 84001. Because ALH 84001 is ∼4 Ga old, the H‐isotopic composition suggests that a large fraction of the initial martian atmosphere had already escaped by 4 Ga.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380285706412504449","@type":"Researcher","foaf:name":[{"@value":"N.
