Foto das dunas do Parque Estadual do Jalapão, no leste do estado do Tocantins, Brasil. A paisagem registra a interação entre depósitos arenosos quaternários, drenagens associadas ao rio Novo e formas residuais do relevo da Serra Geral do Tocantins. Ao fundo, destacam-se superfícies aplainadas e morros testemunhos esculpidos em rochas sedimentares, elementos característicos da evolução geomorfológica regional da bacia do Parnaíba. O campo de dunas constitui uma das feições geomorfológicas mais emblemáticas do Cerrado brasileiro, refletindo processos eólicos, fluviais e intempéricos atuantes em ambiente sazonal tropical.

Cover caption: Photo of the dunes of Jalapão State Park, eastern Tocantins State, Brazil. The landscape records the interaction between Quaternary sandy deposits, drainage systems, and residual landforms of the Serra Geral do Tocantins. In the background, planation surfaces and buttes carved into sedimentary rocks stand out as characteristic elements of the regional geomorphological evolution of the Parnaíba Basin. The dune field represents one of the most emblematic geomorphological features of the Brazilian Cerrado, reflecting aeolian, fluvial, and weathering processes operating under a tropical seasonal environment.
