Abstract
Resolved measurements of the relative abundances of 13CDH3 and 12CD2H2 from a Taiwan mud volcano confirm that thermogenic CH4 with a formation temperature of 150 °C is bubbling from a pool of liquid mud. Analysis for both doubly-substituted molecules provides confirmation that isotopic exchange equilibrium was achieved between methane isotopologues. Methane extracted from the headspace of core samples taken from sediments deposited proximal to the bubbling pool of mud shows small departures from isotopic equilibrium.
