Abstract:

We have measured leaf wax n-Alkanes from a Loess Paleosol Sequence (location: 47.56819 / 7.88053) ranging back to MIS 4. The data set contains n-Alkane patterns, Deuterium and Radiocarbon.

We also present some calculations, derived from the Patterns:

Average chain length gives a hint whether trees/shrubs or grasses were the dominant vegetation. The higher the value, the higher the contribution of grasses.

ACL=(27 x nC_27+29 x nC_29+31 x nC_31+33 x nC_33)/(nC_27+nC_29+nC_31+nC_33 )

OEP is a marker for degradation. The higher the values, the less degraded are the n-alkanes.

OEP=(nC_27+nC_29+nC_31+nC_33)/(nC_26+nC_28+nC_30+nC_32 )

For more information, further calculations and discussion see the related manuscript.
