Based on the mineral associations of the metamorphic rocks of Arquía Group on its type locality in Colombia, pressure-temperature conditions of metamorphism and associated P-T path were built. The analysis of the mineral assemblages indicates a prograde regional metamorphism, which varies from low to medium grade and is represented by greenschist, epidote-amphibolite and amphibolite facies. Results based in the prograde mineralogy [actinolite + chlorite + albite + quartz + muscovite + clinozoisite + zoisite + epidote for greenschist facies and hornblende + clinozoisite + zoisite + epidote + garnet + albite ± quartz for epidote-amphibolite and amphibolite facies] indicate a constant increase of the metamorphic conditions from 433°C and 11.8 Kbar to 696°C and 14.4 Kbar in the metamorphic peak. Retrograde mineral assemblages [muscovite + chlorite + clinozoisite + zoisite + epidote + albite + actinolite] indicate new metamorphic conditions between 417-357°C and 8.1-6.5 Kbar. Additionally, four deformation events and evidences of shear zone and intracrystalline deformation were found in these rocks.
