Dataset for "One of the most ancient scenarios of diamond formation revealed experimentally: sulfidation of siderite in the course of Mesoarchean subduction"

This repository contains the raw data massifs to constrain Raman, IR- and PL spectra, recorded on diamonds, synthesized in the course of siderite-sulfur interaction under pressure of 6.3 GPa and temperature of 1550 °C. They comprise:

1) Raman spectrа of the quenched carbonate melt entrapped as the inclusion in the diamond. The Raman spectral pattern of this inclusion has host diamond, carbonate, graphite and magnetite peaks.

2) Raman spectra of graphite and sulfide entrapped as the inclusion in the diamond.

3) Raman spectra of various sulfur-bearing species in the diamond inclusions: (a) elemental sulfur, (b) anhydrite, (c) sulfate anion and (d) hydrosulfate anion.

4) Representative IR absorption spectra of synthesized diamond crystals.

5) Typical photoluminescence spectra of synthesized diamond crystals, measured at 80 K with excitation at 395 nm and 532 nm.
