DescriptionThe Agoult belongs to a rare class of stony meteorites called eucrites. Compositionally eucrites resemble certain terrestrial volcanic rocks, such as the basalts which crystallize from lava on or near the Earth\'s surface. They may have originated from asteroids large enough to have once had molten interiors. It is thought that the less dense or 'lighter'components in magma separated from the denser components, to form outer crusts of silicate-rich rocks such as the eucrites, in much the same way as basalts formed on the Earth. Eucrites do not contain chondrules, small round aggregates of minerals, which are usually preserved in more primitive stony meteorites. This evidence supports the idea that eucrites formed from magma of melted primitive rock; melting would have destroyed any chondrules present.
