Lipid distribution in a subtropical southern China stalagmite as a record of soil ecosystem response to paleoclimate change
Lipid extracts from a 61.7-cm-long subtropical stalagmite in southern China, spanning the
period of ca. 10,000–21,000 yr ago as constrained by U–Th dating, were analyzed using
gas chromatography–mass spectrometry. The higher plants and microorganisms in the
overlying soils contribute a proportion of n-alkanes identified in the stalagmite. The
occurrence of LMW (lower molecular weight) n-alkanols and n-alkan-2-ones in the
stalagmite was mainly related to the soil microorganisms. We suggest that HMW (higher …
