Bernasconi SM, et al. Among authors: john cm. Geochem Geophys Geosyst. 2021 May;22(5):e2020GC009588. doi: 10.1029/2020GC009588. Epub 2021 May 24. Geochem Geophys Geosyst. 2021. PMID: 34220359 Free PMC article.
To address interlaboratory differences, we first provide consensus values from the clumped isotope community for four carbonate standards relative to heated and equilibrated gases with 1,819 individual analyses from 10 laboratories. Then we analyzed the four carbonate s …

Mineral carbonation of peridotite fueled by magmatic degassing and melt impregnation in an oceanic transform fault.
Klein F, Schroeder T, John CM, Davis S, Humphris SE, Seewald JS, Sichel S, Bach W, Brunelli D. Klein F, et al. Among authors: john cm. Proc Natl Acad Sci U S A. 2024 Feb 20;121(8):e2315662121. doi: 10.1073/pnas.2315662121. Epub 2024 Feb 12. Proc Natl Acad Sci U S A. 2024. PMID: 38346185 Free PMC article.
We studied the formation of soapstone (magnesite-talc rock) and other magnesite-bearing assemblages during mineral carbonation of mantle peridotite in the St. Paul's transform fault, equatorial Atlantic. Clumped carbonate thermometry of soapstone yields a formation (or equ …

Reducing contamination parameters for clumped isotope analysis: The effect of lowering Porapak™ Q trap temperature to below -50°C.
Davies AJ, John CM. Davies AJ, et al. Among authors: john cm. Rapid Commun Mass Spectrom. 2017 Aug 30;31(16):1313-1323. doi: 10.1002/rcm.7902. Rapid Commun Mass Spectrom. 2017. PMID: 28488739 Free article.
CO(2) from two contaminated carbonate samples was then purified at PPQ trap temperatures between -25 and -65C and measured by IRMS to determine changes in mass excesses on m/z 47, 48 and 49. Finally carbonate standards, Carrara marble (CM) and ETH3, were purified at PPQ tr …
