Overview

Analysis reveals melt inclusions from xenoliths indicating incongruent melting and high temperatures in crustal anatexis.

Key Points

  • Xenolith grain characteristics show evidence of incongruent melting processes at the crust-mantle interface.
  • Melt inclusions demonstrated potassium-rich acid melts whose formation temperature ranged between 950-1000°C.
  • Thermobarometric analysis of inclusions indicates high pressure conditions exceeding 1.5 GPa during melt formation.
  • Presence of carbon dioxide fluid in the melts suggests a crucial role in the petrogenesis of these samples.
