Impacts are the fundamental process in the formation and evolution of planets and small bodies of the Solar System. These shock process could be recorded by meteorites at microscale levels. Among all meteorite groups, the L group ordinary chondrites retain the most complete record of shock metamorphism, which provides important constraints on the timing and physical conditions of the impacts. Mineralogical evidence indicates that within 100 Ma of the formation of the Solar System, the L chondrite parent body (LCPB) may experience catastrophic distribution and be reassembled shortly after. At around 4.48 Ga, the primordial asteroid belt was widely impacted, speculatively resulting from the peak arrival time of ejecta debris from the Moonforming giant impact at the primordial main belt. Some celestial bodies in the inner solar system, including the LCPB, experienced a contemporaneous impact period at about 800 Ma, which was possibly caused by the disruption of a large asteroid at this time. Abundant chronological and mineralogical evidence from L chondrites indicate the distribution of LCPB at approximately 465 Ma. This event also affected the Earth by a dramatic increase in the flux of Lchondritic material and left prominent traces in stratigraphic records. Combined with available literature data of L chondrites associated with this catastrophic event, our results suggest that the LCPB suffered a catastrophic collision with a large projectile (with a diameter of at least 18~22 km) at a low impact velocity (5~6 km/s). The chronological record of L chondrite suggests that LCPB was minimally affected by the Late Heavy Bombardment (LHB). This may be because the distribution of L chondrite asteroid source is limited in main asteroid belt, or the primordial asteroid belt was less intensely collided than originally envisaged. Therefore, a more extended and more modest collision rather than a prominent and narrow impact spike at 3. 9 Ga of LHB is implied.
