During 2013 - 2014 archaeological research was undertaken in San Gregorio (Xochimilco) and Tepexpan, Basin of Mexico, to recover evidence for human activity associated to the preceramic period in the lakebed area of Chalco-Xochimilco and Texcoco. One of the specific objectives of this research is to characterize soil conditions north and south of modern Mexico City, during the early agriculture period (6500-4000 BP) by means of paleopedological analysis, and evaluate environmental and anthropogenic processes involved in site formation using micromorphology, pollen, phytoliths and stable isotope analysis. These data will be correlated with human activities in both sites, the introduction of domesticated plants and the effects of management by human groups on the lacustrine environments before the first villages in the region were established.
