  abstract = {{A}irborne radiometric (gamma-ray) data provide estimates of the concentrations of potassium ({K}), thorium ({T}h), and uranium ({U}) in soil, regolith, and bedrock. {R}adiometric data constitute an important source of geochemical information, commonly used in mineral exploration and for geological mapping of {E}arth and other planets. {A}irborne radiometric data have rarely been applied to the exploration and analyses of impact structures, in contrast with other conventional geophysical tools (e.g., gravimetry, magnetism, and seismic reflection/refraction). {T}his work represents the first systematic survey of the {K}, {T}h, and {U} radiometric signatures of {A}ustralian impact structures, based on the continent-wide airborne radiometric coverage of {A}ustralia. {W}e first formulated several hypotheses regarding the possible causes of formation of circular radiometric patterns associated with impact structures. {T}hen, the radiometric signatures of 17 exposed impact structures in {A}ustralia were documented. {O}ur observations confirmed the supposition that impact structures are commonly associated with circular radiometric patterns. {W}e then selected the five structures with the most prominent circular radiometric patterns ({G}osses {B}luff, {L}awn {H}ill, {A}craman, {S}pider, and {S}hoemaker), and we discuss the possible origin of these anomalies. {B}ased on these five case studies, we argue that such patterns result from either crustal deformation induced by the impact event and/or from postimpact superficial processes controlled by the crater topography. {T}his work also suggests that airborne radiometric data may be useful, in combination with other geophysical tools, in the search for new possible impact structures.},
