Exhibition Text

Less melting

Kenna, a ureilite, comes from an asteroid that did not completely differentiate. Instead, it only partially melted, then cooled and crystallized before it could separate into iron and stony parts.

Some ureilites contain primitive particles such as microdiamonds and chondrules that survived partial melting of the surrounding rock. In more fully melted meteorites, no chondrules remain.
