Exhibition Text

Broken Crystals

Willamette once had a Widmanstätten structure similar to the one in Owens Valley (above). However, its crystals were reheated and recrystallized into new shapes. In this case, the heat came from collisions with asteroids in space. Other iron meteorites, however, were partially recrystallized on Earth when people used them as anvils.
