Data for Reaction pathway, mechanism and kinetics of thermochemical sulfate reduction: insights from in situ Raman spectroscopic observations at elevated temperatures and pressures

Description

Raman spectra of all reaction systems and calculated peak area ratio between the TSR-involved species and N2. The simulation result of tonnages of Zn precipitated from ore-forming fluid is also contained in the files.

Steps to reproduce

FSCCs were prepared in the State Key Laboratory for Mineral Deposits Research, Nanjing University (China). A heating-cooling stage (CAP500, Linkam Scientific Instruments Ltd.) was used to control the sample temperatures. Raman spectra were acquired using a high-resolution Raman spectrometer (JY/Horiba LabRAM HR800) with a 532 nm laser from an air-cooled, frequency-doubled Nd:YAG excitation source, with a 50× objective lens (Olympus), and an 1800 groove/mm grating with a spectral resolution of approximately 1 cm−1. Spectra were processed using Labspec (v5.58.25, HORIBA Scientific) software and Jandel Scientific Peakfit v4.04 program.
