The small chip of Tagish Lake analysed herein had a higher carbon abundance (5.81 wt%) than any other chondrite, and a nitrogen content (˜1220 ppm) between that of CI1 and CM2 chondrites. Owing to the heterogeneous nature of the meteorite, the measured carbon abundance might be artificially high: the carbon inventory and whole‐rock carbon isotopic composition (δ<jats:sup>13</jats:sup>C ≅ +24.4%<jats:sub>o</jats:sub>) of the chip was dominated by <jats:sup>13</jats:sup>C‐enriched carbon from the decomposition of carbonates (between 1.29 and 2.69 wt%; δ<jats:sup>13</jats:sup>C ≅ +67%<jats:sub>o</jats:sub> and δ<jats:sup>18</jats:sup>O ≅ +35%<jats:sub>o</jats:sub>, in the proportions ˜4:1 dolomite to calcite). In addition to carbonates, Tagish Lake contains organic carbon (˜2.6 wt%, δ<jats:sup>13</jats:sup>C ≅ −9%<jats:sub>o</jats:sub>; 1033 ppm N, δ<jats:sup>15</jats:sup>N ≅ +77%<jats:sub>o</jats:sub>), a level intermediate between CI and CM chondrites. Around 2% of the organic material is thermally labile and solvent soluble. A further −18% of the organic species are liberated by acid hydrolysis. Tagish Lake also contains a complement of presolar grains. It has a higher nanodiamond abundance (approximately 3650–4330 ppm) than other carbonaceous chondrites, along with ˜8 ppm silicon carbide. Whilst carbon and nitrogen isotope geochemistry is not diagnostic, the data are consistent with classification of Tagish Lake as a CI2 chondrite.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380568468308490753","@type":"Researcher","foaf:name":[{"@value":"M.
