Data availability

The post-entrapment depth and latest recrystallizing depth can possibly be determined by considering the pressure and density of the CO2 fluid inclusion data from the Phayaung Taung region. The density of the CO2 fluid inclusion was determined using the Wang equation, as shown in Table 1. Using the density of the fluid inclusion data, we were able to determine the estimated pressure of the CO2 fluid inclusion, as seen in supplemental table 1 and 2.
