Determining the relationship between the orogens and sedimentary basins is an important aspect of tectonics and geodynamics research. This is wellexemplified by the coupling between the orogens and sedimentary basin due to continental lithospheric flexure. This contribution focuses on the continental lithospheric flexure and shows the relationship between the shape of the single or multiple topographic loads, the shape of the flexural basin, and the effective elastic thickness (Te). Based on theory and case studies, this study shows how flexural modeling applies to research associated with the orogens and sedimentary basin evolution. By combining paleoenvironment indicators with flexural modeling, we also propose a novel approach to quantitatively estimate the paleoelevation of an orogenic belt that accounts for the flexural subsidence of a basin that was influenced by sea incursion. Different from other paleoaltimetry approaches that connect the temperature or pressure and elevation, this new approach emphasizes that the relief of the topographic load equals the paleoelevation of the orogenic belt during the time when the sea incursion occurs in the flexural basin, providing a new way to understand the paleoelevation of the orogenic belts. Finally, this work summarizes the caveats of flexural modeling and gives some new perspectives on documenting the basement feature of sedimentary basins, paleoelevation reconstruction, and the design and application of the software associated with flexural modeling.
