【摘要】 介绍了沉积有机质演化的基本规律及其影响因素 .在此基础上 ,讨论了利用有机质演化特征研究造山带的有关问题 ,如重塑造山过程 ,造山带空间特征以及造山带变形标志等 ;认为造山带中的沉积有机质演化特征记录了温度、围压、应力和应变等地质环境方面的丰富信息 ,从而有可能成为重建造山过程 ,尤其是极低级变质作用阶段的敏感地质温压计 .更多还原

【Abstract】 The evolution features of depositional organic matters in orogenic belt may reflect a lot of geological information such as temperature, confining pressure, stress, strain, and so on. Organic matters maybe come into use as the sensitive temperature pressure meter for reconstructing of orogenic process, especially at the stage of very low grade metamorphism. The basic evolution law of organic matters and its control factors were introduced. Based on this, the possible uses of analyzing the evolution features of organic matters in studying orogenic belt were discussed.更多还原
