dc.description.abstract | Carbon isotope of total carbon ( 13CTOC), long-chain n-alkanes and their compound-specific carbon isotope ratios ( 13CALK) were investigated in the Hanon paleo-Maar sediment, Jeju Island of Korea to understand paleovegetationchanges and their paleoclimate linkages. Based on the organic geochemical data (TOC (%), TN(%) and their  13CTOC and  15NTN ), the core column stratigraphy was divided into three units from bottom to 12.5 ka (UnitI),12.5 ~2.5 ka (Unit II) and 2.5 ka to core tope (Unit III), respectively. In particular,  13CTOC showed marked fluctuation from -17.31‰ to -28.68‰, suggesting different organic carbon sources.ionchanges and their paleoclimate linkages.
