Laboratory of Sedimentology and paleoenvironment change (LSPC) belongs to the paleoenvironment division. The mission of the LSPC is to discover the tempo-spatial variability of dust provenance and East Asian Monsoon by means of investigating sedimentology and geochemistry of eolian dust deposition records on a wide range of time-scales. The goals are to provide geological evidences for the interactions between regional and global climatic changes, and to better predict the future climate change based upon robust understanding of natural climate variability in the past. The emphasis of current research is on tectonic-to-millennial variability and dynamics of the coupled monsoonal-arid environmental systems since the late Cenozoic.
1. Asian dust source tracing
2. East Asian monsoon variation on tectonic-millennial scale
3. Comparison between ocean and land palaeoclimatic records

The LSPC is equipped with Mastersizer 2000 particle size analyzer and Minolta CM-700d Spectrophotometer, which can be used to measure the particle size distribution and color reflectance of loess, lake and marine sediment samples. The results are applied to reveal the transport dynamics of eolian dust and to reconstruct the evolutionary processes of sedimentary environment.
