Proposal/Expertise: The late Pleistocene and Holocene soils in the Parana - Plata river basin as objects of paleo-ecological and paleo-climatic reconstructions
Description of proposal or expertise:
In a number of methods for study of the geographic ambience evolution the method of soil chronosequences has an important significance. The method is consisted of combined study of unequal-age paleo-soils and their modern natural analogs. Comparison of properties of the modern (full - holocene) soils with ancient soils makes it possible to establish of bioclimatic situations and other factors of natural environment evolution. The greater quantity of unequal-age soils is studied in the concrete territory, the more complete information about changes in time of climate, soils, vegetation and other components of natural landscapes becomes.
Problems to be solved and results:
The essence of proposal project consists in development and a comparative study in the Parana-Plata river basin of modern soils and series of soils, "switched off" from the soil formation process in different times during the period between late Pleistocene - early Holocene and XVII-XVIII centuries. The objects, by which it can be to reveal the paleo-soils, are following: depressions of natural erosion net (above-floodplain terraces, flood lands of rivers and bottom of beams), loess geological baring, territory with eolian relief (sandy dunes, etc.), high earthen ejections of the digging animals, archaeological monuments of different historical epochs. Good safety have holocene paleo-soils, buried under the earthen mounds of heavy granulometric composition with thickness of more than 1,5 meter.
