In Situ Quantification of Carbonate Species Concentrations, pH, and pCO2 in Calcite Fluid Inclusions Using Confocal Raman Spectroscopy

Carbonate minerals are globally distributed on the modern and ancient Earth and are abundant in terrestrial and marine depositional environments. Fluid inclusions hosted by calcite retain primary signatures of the source fluid geochemistry at the time of mineral formation (i.e., pCO
