Abstract
In continental wet tropical settings, Late Pleistocene and Holocene cover units record climate pulses influence over continental geomorphologic systems and contribute to better understand of the relief genesis. The selected study area, comprising two hydrographic basins within the Paulista Peripheral Depression (PPD), comprehends a relevant framework from Southestern Brazil, a widely studied region categorized in relation to its planation surfaces and overlaying materials, which is the object of this research. Based on the OSL geochronology applied to several surficial sedimentary units within the PPD, but also the litostratigraphic and sedimentological (hydrodinamic interpretation) characterization of the sedimentary cover, it was possible to determine the depositional setting and sediment rate associated with each surficial unit, correlating such information to remarkable regional and global climate events, establishing a strict relation between climate pulses and surficial geomorphologic processes as feedback to seek a dynamic equilibrium within the tropical-continental system.
