Final simulated Chicxulub crater for a 30 and 60 impact angle. Shown are cross-sections, along the plane of trajectory, through the final simulated craters formed by a 30 (a) and 60 (b) impact, with x ¼ 0 defined at the crater centre (measured at the pre-impact level); the direction of impact is from right to left. Sandy-brown tracers indicate the final position of the upper 3 km of the pre-impact target (sedimentary rock); red tracers indicate the position of melt; tracers with blue–white shading indicate shock pressures of simulated peak-ring materials. The geometric centre of the crater rim defines the coordinate origin (x ¼ 0); negative x-values are downrange.
