Round versus angular crystals
Most pallasites, including Springwater, have rounded olivine crystals. But in Huckitta, the olivine crystals are much more angular. Both mixtures originated when molten iron was forced between olivine crystals in a partially melted asteroid. The rounded crystals formed when angular crystals partially melted and recrystallized — perhaps because they were deeper inside and thus took longer to cool.
