| 摘 要： | 陆架边缘海沉积物是重要的生物地球化学反应器,海洋中90%以上的有机质沉积于此并在早期成岩作用过程中矿化.其矿化路径包括有氧呼吸、反硝化、锰氧化物还原、铁氧化物还原、SO4(-2)还原和CO2还原,并按生成自由能减少的顺序依次发生,构成理想的氧化还原序列.定量研究有机碳矿化路径及其对有机质矿化的相对贡献对揭示能量分配和碳...

| Abstract: | Continental margin sediments are an important biogeochemical reactor,where 90% of organic matter(OM) is deposited and remineralized.OM remineralization proceeds from the use of O2,NO-3,Mn(IV)-oxides,Fe(III)-oxides,sulfate,and finally CO2 according to the gains of free energy yield,forming an ideal redox sequence.Differentiating various diagenetic pathways and their relative contributions to OM remineralization is of ecological importance for understanding energy partitioning and carbon cycling,and of biogeo... |
