The ejecta and crustal thickness after postexcavation movement for the impact of a 780-km diameter impactor at 6.4 km/s. The impact site is at 0°. The gray section from 0 to 60° represents the size of the transient crater (see Figure 6). Within the transient crater, the ~25- to 30-km-thick crust (average) includes the deposited (orange points) and excavated crustal material that underwent postemplacement transport (green points within 40-60 degrees). The impactor and ejecta thickness distribution are binned into discrete rings of 2-arc degree width from the impact site up to an arc distance of 180°. The orange line represents the impact-derived crustal thickness composed of the displaced crust (blue dashed line) and ejecta (green points), starting from 40° from the impact site. The blue dashed line represents the displaced crust that is originally adjacent to the crater rim and then was dragged by the outward material flow during the impact cratering process.
