Chondrule
Chondrules in the chondrite Grassland. A millimeter scale is shown.
Chondrules and the Origin of Meteorites
"The whole is simpler than the sum of its parts." - W. Gibbs
Building blocks of planetary bodies ...
Chondrule: Roughly spherical objects found in a type of meteorite called chondrites. Most chondrules are 0.5 to 2 millimeters in size and are composed of olivine and pyroxene, with smaller amounts of glass and iron-nickel metal.
Chondrule
small, glassy spheres commonly found in meteorites.
Chromatic aberration
an optical lens defect causing color fringes, because the lens material brings different colors of light to focus at different points.
Chondrule - A small, spherical body embedded in a meteorite. Chondrules are composed of iron, aluminum, and magnesium silicate rock
Chromosphere - The part of the Sun's atmosphere between the photosphere and the corona ...
chondrule: Round, glassy body in some stony meteorites; believed to have solidified very quickly from molten drops of silicate material.
Chondrules
Small spherical grains varying from microscopic size to the size of a pea, usually composed of iron, aluminum, or magnesium silicates. They occur in abundance in primitive stony meteorites.
chondrule 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.
"Lead isotopic ages of chondrules and calcium-aluminum-rich inclusions.". Science (New York, N.Y.) 297 (5587): 1678-83. doi:10.1126/science.1073950. PMID 12215641.

Specimens of the meteorite were found to contain a fine-grained carbon-rich matrix studded with many chondrules, both matrix and chondrules consisting predominantly of the mineral olivine.
Iridium is rare on Earth except near the Earth's center, but relatively abundant in chondritic meteors (stony meteors with chondrules, spherical blobs of silicates which pre-date planetary formation).
Chondrules show evidence that they were formed at about the same time as the planets - it has been suggested that they formed in the Solar nebula by impact between high-velocity grains.
Unlike achondrites, chondrites contain chondrules, which are spheres or spheroids of olivine and other minerals embedded in a matrix or groundmass; ...
On this rock, recovered in 1988 and called Alan Hills 84001 (ALH84001 for short), the scientists found small, worm-shaped structures called chondrules, which form when the rock is subjected to climactic stresses.
CHONDRITIC METEOR
Chondritic meteors are stony meteors with chondrules, tiny glass spheres. These meteors are unchanged since their formation, shortly after the formation of the sun. These meteors consist of elements also common in the Earth's core.
Primitive meteorites, in particular carbonaceous chondrites, contain millimetre to centimetre-sized calcium-aluminum-rich inclusions (CAIs) and chondrules, molten or partially molten droplets that become bound up in the asteroid.
a stony meteorite containing small, round, silicate granules called chondrules
chromosphere
a layer in a star's atmosphere lying below the corona and above the photosphere ...
About 86% of the meteorites that fall on Earth are chondrites, which are named for the small, round particles they contain. These particles, or chondrules, ...
show a diversity of mineral elements including large percentages of silicon and magnesium oxides; the most abundant type of aerolite is the chondrite, so called because the metal embedded in it is in the form of grainlike lumps, or chondrules.
We can picture an IDP as a "matrix" of material with embedded elements which were formed at different times and places in the solar nebula and before our solar nebula's formation. Examples of embedded elements in cosmic dust are GEMS, chondrules, ...
