This research delves into the geochemical aspects, non -isothermal thermogravimetric analysis, and model -free kinetics of oil shale samples from the & Ccedil;eltek region in Amasya, T & uuml;rkiye. Shifting the focus to the core of the research, thermal and mass spectrometric analysis (TG-DTG-MS) experiments were conducted in an air atmosphere, employing three distinct heating rates of 10, 20, and 30 degrees C/min. The outcomes revealed two successive reaction stages: the breakdown of organic matter and mineral decomposition. In the breakdown stage, activation energy values exhibited a range of 160- 163 kJ/mol, while in the mineral decomposition stage, the values varied between 208-214 kJ/mol, using model -free kinetic models.
