What Does POI Stand For?
POI stands for Plagioclase Olivine Inclusions
POI, or Plagioclase Olivine Inclusions, refers to mineralogical formations where plagioclase and olivine crystals are enclosed within a matrix of other minerals. These inclusions are significant in petrology and geochemistry as they provide valuable insights into the conditions of magmatic processes and the evolution of igneous rocks. The study of POIs aids in understanding the thermal history and the chemical environment of their host rocks, contributing to the broader knowledge of Earth's geological history.
