Chondrules in the chondrite classification Grassland. A millimeter scale is shown. Chondrules in the Carbonaceous Chondrite NWA 13887. A chondrule (from Ancient Greek χόνδρος chondros, grain) is a round grain found in a chondrite. Chondrules form as molten or partially molten droplets in space before being accreted to their parent asteroids.

Tenebrarum et nebulae, Regis regum rectissimi. Diesque mirabilium Tonitruorum fortium, Dies quoque angustiae, Maeroris ac tristitiae. Regis regum rectissimi. In quo cessabit mulierum Amor et desiderium, Nominumque contentio Mundi hujus et cupido. Regis regum rectissimi prope est dies domini. King of kings and of lords most high, Comes his day ...
There are many indicators why some achondrites are deemed primitive. Some contain relic chondrules (e.g. Acapulcoite, Lodranite) and some have oxygen isotope ratios that are similar to chondrites. There are similarities in trace element concentrations between primitive achondrites and chondrites.
Dos EPs is the first compilation album by the American stoner rock band Nebula. [9] [10] It was released on May 28, 2002, by MeteorCity, and later reissued in 2018 by the band's current label, Heavy Psych Sounds Records.

The 1 in C1 stands for the type 1 meteorites in the older classification scheme of Van Schmus-Wood, [4] still used for petrography. Petrographic type-1 meteorites, by definition, have no fully-visible chondrules .
Ordinary chondrite NWA 3189 sliced. Field of view c. 2.2 cm across. NWA 3189 has been classified as an LL3.2–3.4 ordinary chondrite ("LL" means very low total iron content; "3" refers to well-preserved chondrules – the rock has not been subjected to metamorphism intense enough to disrupt the chondritic texture).
LL chondrites contain the largest chondrules of the ordinary chondrite groups, averaging around 1 millimetre (0.039 in) diameter.. The LL group includes many of the most primitive ordinary chondrites, including the well-studied Semarkona (type 3.0) chondrite.
