2017/4/10
Oxygen isotope ratios (d18O) of tree-ring cellulose in pine (Pinus densiflora) and oak (Quercus serrate and Quercus
variabilis) growing in central Japan from 1970 to 2011 share a common inter-annual ...
Late Pleistocene variation in lignin and fatty acids from core TKN-2004 in a small mountain basin in central Japan
lignin vegetation TMAH thermochemolysis glacial Takano Basin central Japan Late Pleistocene
2017/4/11
We generated a record of lignin and fatty acid compositions from the TK-2004 core in Takano Basin, central Japan,
during 39–162 ka by TMAH-thermochemolysis-GC/MS. We tested lignin and fatty acid comp...
