Catastrophic disruption of differentiated asteroids creates a sheet-like mix of core and mantle fragments with uniform iron-rock ratios that reaccumulate into iron-rich rubble piles if the core is molten.
Collisional and dynamical models indicate the Eulalia parent body disruption ~800 Ma near the J3:1 resonance produced an impact shower that accounts for observed lunar craters formed near that time.
