- Abstract:
- The emerging research area of palaeoclimate reconstruction from diatom-isotope analysis is presently limited to lake sediments that are near-diatomite or the concentration of fine-silt sized silicate minerals is low. This excludes many important lakes that contain no other host for climatically sensitive isotopes. Here we will develop a generic methodology for the separation of diatoms from sediments using split-flow thin-cell fractionation (SPLITT). SPLITT will first be tested on known sediments and then applied to crater lakes from Mt Kenya and S. Tanzania that have exceptional sedimentary sequences (40-50 ka), are very well dated, and are part of multiproxy studies. The isotope data will be used to reveal climate fluctuations from the equatorial and southern tropical region of E. Africa and to further develop understanding of diatom-isotope analysis.
