THE DIFFERENTIAL THERMAL ANALYSIS (DTA) CHARACTERISTICS OF MACERAL AND THEIR RELATION TO OIL ANO GAS GENERATION

The DTA characteristics of main maceral and their thermal evolution products of coals and oil source rocks in our country have been investigated in this study.The results show that different kinds of maceral have different DTA characteristcs. Since the result sof organic differential similar thermal analysis reflect the chemical structure of maceral, thy wiel have a good relation with oil and gas generation.
