A Collisional History
This meteorite contains a wide variety of chondrule types, including radial pyroxenes, barred olivine, porphyritic olivines and, more interestingly, a large blob of impact melt!
Impacts were very common in the early Solar System and collisions between asteroids create a huge spike in heat and pressure, crushing and melting the rock which then rapidly crystallises. Impact melts can be found in all meteorite groups, and scientists can use their presence in conjunction with other impact-related features to estimate how much pressure the meteorite experienced and therefore how big the impact was.
