开展下古生界有机质的研究能获得大量关于早期海生生物组成和性质的信息。与中、新生界地层不同的是,这些古老地层中的有机质不含陆相生物,均由海相浮游生物和细菌组成。许多地质体中有机质的性质和生物标志物的成因,往往由于生物输入的多源性而无法得到正确的解释。下古生界有机质的研究能深化 Carrying out the study of the Lower Paleozoic organic matter can yield a wealth of information on the composition and nature of early marine organisms. Unlike the Mesozoic and Cenozoic strata, the organic matter in these ancient formations is free of terrestrial organisms and consists of marine plankton and bacteria. The nature of organic matter and the cause of biomarkers in many geologic bodies are often not correctly explained by the multi-source nature of biological inputs. Lower Paleozoic organic matter can deepen the study
