1. A method comprising:
extracting BTEX compounds from a sample;
measuring an isotopocule composition of the BTEX compounds; and
determining a characteristic of the sample based on the measured isotopocule composition,
wherein the characteristic of the sample comprises a weathering of the sample,
wherein the weathering of the sample is a chemical weathering of the sample or a biological weathering of the sample,
wherein an amount of the chemical weathering is estimated based on an identified change in an amount of hydroxide (—OH) in the sample, or
wherein an amount of the biological weathering is estimated based on an identified change in location and quantity 13C-13C of bonds in the sample.
