A summary of the influencing factors on the clumped isotope values of methanogenesis. The points on this figure show the average measured and “pure” clumped isotope values of each methanogenic pathway. The arrows show the processes that can influence the clumped isotope signatures, and the gray area shows the microbial methanogenesis field defined by the previous studies.

The Clumped Isotope Signatures of Multiple Methanogenic Metabolisms

by Keith CowingJuly 28, 2025July 28, 2025

Methane is a potent greenhouse gas, an important energy source, and an important part of the global carbon cycle. The relative abundances of doubly substituted (“clumped”) methane isotopologues (13CH3D and […]
