  abstract = {{T}opographic escarpments are striking geomorphic features shaping the {E}arth's surface, often forming distinct water divides in tectonically stable regions. {T}his study presents a new analysis of the geomorphic evolution of the {S}erra {G}eral {E}scarpment in the {S}tate of {G}oias, {C}entral {B}razil, using in situ-produced cosmogenic nuclides. {T}he objective is to quantify {Q}uaternary denudation rates associated with different geomorphic compartments of this regional-scale escarpment by measuring the concentrations of 10{B}e, 26{A}l, and 36{C}l in river-borne sediments and bedrock outcrops. {T}he results reveal three distinct denudation regimes: the summit surface of the {W}estern {B}ahia {P}lateau (7.4 f 0.2 m {M}yr-1), the pediplanation surface at the toe of the {S}erra {G}eral {E}scarpment (22.6 f 0.6 m {M}yr-1), and the steep escarpment slopes (84.4 f 3.8 m {M}yr-1). {T}he significant influence of regolith burial and landslides on isotopic signatures is highlighted, underscoring the importance of accounting for these processes when interpreting cosmogenic nuclide data. {E}stimated escarpment retreat rates range from 30 to 90 m {M}yr-1 along active segments, while the southern region shows stabilization indicative of an advanced stage of landscape evolution. {T}hese findings demonstrate the complex interplay between geomorphic processes, lithology, and climate in shaping escarpments within continental interiors. {P}reliminary geomorphic evidence suggests that escarpment retreat and pediplanation at the glint's base may have initiated as early as the upper {M}iocene. {T}his study establishes a framework for understanding tropical plateau erosion and offers insights into the evolution of similar escarpments worldwide.},
