Noble gas and clumped methane data for samples from Anyue gas field, China (NERC Grant NE/T004452/1)

This dataset contains 6 tables covering all analytical data for samples collected from the Anyue gas field, central Sichuan Basin, China. Table 1 includes major gas species and stable carbon and hydrogen isotopes. Table 2 includes results for methane clumped isotopes and calculated methane formation temperatures of gas samples. Table 3 includes noble gas concentrations. Table 4 includes noble gas isotopic ratios. Table 5 includes parameters used in methane emission model and calculating total volume of methane emission. Table 6 includes gas composition and stable carbon and hydrogen isotope characteristics of major gases produced in the pyrolysis experiments (thermally equilibrated methane between 400~500 in theory) and working reference gas, and their methane clumped isotope values.

Statement

Samples for noble gas and CH4 clumped isotope analysis were collected using 10 mm diameter internally polished refrigeration grade copper tubes sealed with stainless steel pinch-off clamps on both ends. Additional samples for the analysis of gas composition, carbon and hydrogen isotopes were collected using stainless steel cylinders. Bulk gas content as a percentage was determined using an Agilent 6890N gas chromatograph-mass spectrometer (GC-MS). Carbon and hydrogen isotope values were measured using GC-IRMS of Agilent 6890N-Isoprime 100 and Thermofisher 1310-Delta V, respectively. Methane clumped isotopologues were measured by a tunable infrared laser direct absorption spectroscopy (TILDAS, Aerodyne). Noble gas abundance and isotopic ratios were determined by an Isotopx NGX noble gas mass spectrometer.
