摘要
Method for determining the radical content in dispersed organic matter from coal, asphalt, petroleum and sedimentary rocks by means of ESR is discussed. Factors affecting the results are also considered. The possibility of using radical content as an indicator is suggested for the degree of metamorphism of the dispersed organic matter and for other geologic problems pertaining to sedimentary rocks and deposits.From the variation of relative concentrations of radical in flame coal samples determined after experiments at elevated temperatures and pressures, the maxium temperature to which the flane coal may have been subjected during its evolution and the temperature-pressure limit for the flame coal-fat coal inversion have been predicted.
