Scientific Program for VI ISFWP

Themes for the Symposium may be expanded or modified depending on correspondence but they are currently expected to include:

1. Paleosol-sedimentary sequences (loess, alluvial, lacustrine, volcanic, etc.) as the record of the Pleistocene and Holocene environmental change *

2. Magnetic properties of Quaternary and pre-Quaternary paleosols and sediments as paleoclimate indicators.

3. Polygenetic models of pedogenesis in relation to Quaternary climatic change in non-glacial subtropical and tropical regions.

4. Biomorphs (pollen, phytoliths, macroremains) in paleosols: research and interpretation problems.

5. Paleopedology and archaeology. Paleopedological evidences of ancient man-induced environmental change.

* Special emphasis will be made on paleoecological interpretation of buried Andosols, paleosols with vertic properties and indurated horizons (tepetates) in the regions of active Quaternary volcanism.

The Symposium organisers are planning a four-day program consisting of three-days of oral presentations interrupted by a one-day mid-symposium field trip, including special session on biomorphs.

Pre-conference field trip to Cuernavaca, Morelos state: relict polygenetic Luvisols with tepetates (indurated horizons in volcanic sediments). 1 day

Mid-conference field trip to Teotihuacan Archaeological Zone, visiting the lacustrine sedimentary sequence of Texcoco ex-lake. 1 day

Post- conference field trip to the area of volcano Toluca: Late Pleistocene and Holocene Andosols buried under ash and pumice flows with special attention to geology and geomorphology. 2 days
