Research Abstract

The objective of this study is to reconstruct long time scale variations in paleovegetation and terrestrial paleoenvironment by analyses of terrestrial plant-derived biomarkers and kerogens in sedimentary rocks from the Cretaceous Yezo Group, Hokkaido, Japan. In particular, we found rapid changes in angiosperm / gymnosperm vegetation ratio and coniferous vegetation evaluated by analysis of terrestrial plant terpenoid biomarkers. Moreover, we suggest that composition of long chain n-alkanols released from resistant macromolecule in kerogen can be useful as an indicator of deciduous broad leaf plant vegetation. Variation in the paleovegetation using the long chain n-alkanols released from kerogen is almost synchronous to that in angiosperm / gymnosperm vegetation using terrestrial plant biomarkers, confirming high applicability of the released n-alkanol proxy for reconstructing paleovegetation from ancient sediment.
