The results of the combined application of a series of analytical methods (clay mineralogy, vitrinite reflectance, Raman microspectroscopy) placed tight constraints on the thermal evolution of the Karakaya Complex of northern Anatolia, a mostly Permo−Triassic subduction-accretion complex resulting from the progressive closure of the Palaeotethys. | Thermal evolution of the Permo−Triassic Karakaya subduction accretion complex between the biga peninsula and the Tokat Massif (Anatolia)
