Data for: Impact of order-disorder in secondary minerals on the multicomponent geothermometry of formation waters and geothermal waters
Description
Multicomponent geothermometry is a critical tool for estimating subsurface temperatures, but its accuracy can be significantly affected by the crystalline order-disorder state of minerals, which is often inadequately represented in standard thermodynamic databases. This study addresses this limitation by systematically incorporating variably ordered forms of key secondary minerals. We demonstrate that the availability of these forms, characterized by the order-disorder parameter Q, and the ability to select the mineral form with the 'right' degree of order-disorder, leads to substantial improvements in the application and reliability of multicomponent geothermometry. In the dataset, the SUPCRT92 database, the LLNL database of PHREEQC (modified as described in this section 2.1), and All PHREEQC input-out files are given.
