I read about an study regarding ejecta. The site was layered with different colors, and a high velocity impact was produced. From the data, ejecta was mapped, by color,and distance from the crater. NOW, this image is ejecta that has been weathered smooth. Could the data be extrapolated by radial distance from crater, what ejecta came from a certain depth? We could possibly study ejecta that came from a depth LOWER than the dune layer in the bottom of the crater.
