有机地球化学研究新进展与展望

阐述了近五年有机地球化学领域的重要研究进展和未来有可能出现新突破的领域。在沉积有机质的性质和结构的认识上有重要进展，由于分子和分子同位素测试技术的进步，发现对有机质参与的地球化学全过程能够进行定性研究。阐述了与烃源岩发育相关的环境与控制因素，但具体形成机制的推断还没有得到沉积记录的验证。生物—有机地球化学在定量环境变化与古生态系统重建研究等方面作出了独特的贡献。未来关于过度型有机质和石油天然气成藏过程定量化重建研究将是有机地球化学有可能出现新突破的领域。新的成份与同位素测定新技术的引入将促进有机地球化学相关研究领域的发展。

An Overview and Perspectives on Organic Geochemistry

The significant achievements and potential new research breakthrough in future of organic geochemistry during the last five years are briefly reviewed. Important progress has been achieved on the property and structure of the sedimentary organic matter. The geochemical process involved by the organic matter has been investigated qualita-tively due to the technique progress on the molecular and molecular isotopes.The environmental and controlling factors on the formation of hydrocarbon source rocks have been deciphered,however,the sedimentary records to support the deduction of the formation mechanism of hydrocarbon source rocks have not been found. The bio-organic geochemistry contributed to the quantitative reconstruction of environmental and paleoecological issues. New progress will be a-chieved on the study of the intermediate type of organic matter and quantitative reconstruction of oil and gas reservoir forming process. Introduction of new techniques in new components and isotopes will further improve investigations of organic geochemistry.
