| Abstract: | Raman-based geobarometry has recently become increasingly popular because it is an elegant way to obtain information on peak
metamorphic conditions or the entire pressure-temperature-time (P-T-t) path of metamorphic rocks, especially those formed
under ultrahigh-pressure (UHP) conditions. However, several problems need to be solved to get reliable estimates of metamorphic
conditions. In this paper we present some examples of difficulties which can arise during the Raman spectroscopy study of
solid inclusions from ultrahigh-pressure metamorphic rocks. |
