A peculiar rounded granule of some mineral, usually enstatite or chrysolite, found imbedded more or less abundantly in the mass of many meteoric stones, which are hence called chondrites.
small (1-10 mm) sphere of glassy silicate.
small, glasslike, round body found in stony meteorites. It is believed to have crystallized from molten droplets present during the initial stages of condensation of the solar nebula.
round glassy structure 0.5 to 5 millimeters in diameter embedded in a primitive stone meteorite. It is a solidified droplet of matter from the early solar nebula and is the very oldest part of the primitive meteorite.
small granule (of e.g. chrysolite) found in some meteoric rocks
A spherical inclusion found in chondritic meteorites. Chondrules are composed of olivine or pyroxene.
Round, glassy part of meteorite made from silicates.
A small, rounded body found embedded in certain meteorites that formed when clumps of dust grains drifting in the solar nebula melted and solidified rapidly, forming small crystals.
round silicate granules that lack volatile element; found in chondritic meteorites (chondrites), they are believed to be primitive Solar System materials.
small sphere of about 1 mm diameter found in meteorites chondrule is composed of formerly melted or partially melted minerals
Rounded granules of olivine and pyroxine found in stony meteorites called chondrites [LCOTE
Most meteorites that fall on Earth are chondrites, which are characterized by the presence of round grains called chondrules (from Greek chondros, grain). Chondrules formed as molten or partially molten droplets in space before being accreted to their parent asteroids. Because chondrites represent the oldest solid material within our solar system and are believed to be the building blocks of the planetary system, it follows that an understanding of the formation of chondrules is important to understand the initial development of the planetary system.
