Implication

Field investigations reveal unique metamorphic conditions in the A Vuong Formation, suggesting distinct geological processes in the region.

Key Points

  • The current pelitic schists show a unique anti-clockwise pressure-temperature trajectory, indicating complex metamorphic histories.
  • Peak metamorphic conditions in the staurolite zone were estimated at 5.5–8.7 kbar and 590–640℃, highlighting geological processes.
  • The findings contrast with the Kham Duc Complex, suggesting unique regional metamorphism patterns in southern Vietnam.
  • Petrological evidence reveals a pressure-temperature transition from andalusite to kyanite stability in the A Vuong Formation.
