“…The detritus fluvial-lagoon sediments constitute the quaternary unit with the largest area of occurrence in the metropolitan region of Recife, being composed of fine sands, silts, clays, diatoms and peat sediments. The mangrove sediments are predominantly made up of clays, silts, fine sands, silica carapaces of diatoms, sponges of spongiaries, organic remains and shells (Demattê et al, 2012;Teramoto et al, 2021;Andrade et al, 2022).…”

In the Prata watershed there are units corresponding to the Pleistocene Terraces and the Fluvium-Lagoon Sediments. This watershed is inserted almost entirely in the area of plateaus (Tabuleiros) with altitudes of 10 to 100 meters, and in areas with altitudes of 2 to 10 meters in the area of floodplains and fluvio-lagoon terraces. The present work aimed to characterize and classify soils in the Brazilian Soil Classification System -SiBCS and correlate them with the IUSS Working Group WRB-FAO (in parentheses), besides evidence some soil-landscape relations, that occur in Pleistocene terraces and fluviumlagoon sediments in the Prata watershed, located in the ecological reserve of Dois Irmãos State Park in Recife -PE, Brazil. Soil samples were used to perform physical, chemical and mineralogical analysis in laboratory. Watershed delimitation, Digital Elevation Model (DEM), slope map, soil map and slope x soil map were obtained and studied. The soils are quite acidic and have a very low natural fertility, with the Latossolos (Ferralsols) predominating in the landscape. The silt and clay fractions of the studied Argissolos (Acrisols) and Latossolos (Ferralsols) presented quartz and kaolinite as the main component. In the profile of Neossolo Quartzarênico (Arenosols) only quartz was identified as a component of the silt and clay fractions. The kaolinitic mineralogy of the clay fraction is consistent with the environment of its formation, that is, hot and humid. There is no relationship between the colors of soils and their exposure to the sun on the slopes where they occur. The occurrence of a sandy and whitish horizon between the litter and the A horizon, is not foreseen in the norms and criteria adopted in the Brazilian Soil Classification System -SiBCS.

“…They are distinct morphological units of origin, but interrelated with each other. The dissection of plateaus by fluvial, pluvial and gravitational agents and the destructive / constructive activity of the sea on the coastal plain, result from tectonic and climatic processes (Teramoto et al, 2021).…”
