This article is concerned with the quaternary's layers in the State of São Paulo. The work was carried out considering first the recent layers, passing after to the ancient ones, aiming to give an idea of the real geographical distribution of the various components of the geological column in that area.

As to map quaternary deposits, generally presented in discontinuous and superposed layers, is a hard task to be executed when on deals with short scale maps, it was adopted, as methodological criterion, the global and successive valuation of the areas where such deposits occur.

To make easier the presentation of the matter in question, this work was subdivided in six main items: search of an itinerary - classifications; the overlaying deposits - basic materials of soil formation; overflowing plains and their basal deposits; the stone lines in São Paulo State: the low terraces; and pediments and detrital pleistocene basins in that State.
