| Organic Carbon Isotopic Characteristics and Their Paleoenvironmental Implications: Case Study of the Tianmushan Peat Bog |
| Organic carbon isotope and lipid biomarker were used to determine paleovegetation characteristics and paleoenvironment changes of the Tianmushan Area,Zhejiang Province since the Middle Holocene.A combined analysis of organic carbon isotope signature and lipid biomarker depicted three remarkable paleoenvironment stages.Before 3200 a BP,the climate was relatively stable in spite of a cold-dry trend in the late stage,implying a transitional period.From 3200 to 700 a BP,it was a changeable period characterized by a couple of warm and cold events.The climate after 700 a BP was relatively warm first and became a bit cooler afterwards,possibly suggesting that the vegetation was dominated by grass plants.Significantly,the results obtained by the authors are well in line with the results of related comparative researches of different areas,thereby demonstrating the global traits and local characteristics of the paleoclimatic process and providing a useful basis for global change comparison. |
