Abstract: [1] We have analyzed the radar-dark parabola deposits associated with impact craters on the surface of Venus using the results of the Magellan radio experiments in both passive and active modes. The extent of mantle deposits is found to be much wider than the dark features observed in synthetic aperture radar (SAR) images. Using the emissivity data, we have classified features coinciding with the radar-dark parabolas into four types related to both differences in ejecta deposition styles for craters of differ…
