Exhibition Text

Surface lava

Eucrites resemble lava from Hawaiian volcanoes. They formed much the same way, when molten basaltic rock flowed onto Vesta's surface. This lava cooled and hardened so quickly that only very small crystals had time to form.

The rapid cooling on Vesta's surface also prevented iron and magnesium from spreading evenly through the larger pyroxene crystals, causing the shifting colors in the magnified photo at right.
