![Pyrite sulfur δ34S values as a function of the natural logarithm of pore water sulfate concentration (r2 = 0.52). Colors correspond to TOC concentration. The solid black line is the line of best fit, with the equation y = −8.4ln([SO4]) − 3.4. The two dashed black lines are parallel to the line of best fit and run 20 ‰ above it and 16 ‰ below it. -- Johns Hopkins University](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/06/An-Unlikely-Hero-In.png?resize=1200%2C720&ssl=1)
