Shock-wave heating model for chondrule formation: Formation of prolate chondrules
Shock-wave heating model for chondrule formation: Formation of prolate chondrulesMillimeter-sized, spherical silicate grains abundant in chondritic meteorites, which are called as chondrules, are considered to be a strong evidence of the melting event of the dust particles in the protoplanetary disk. One of the most plausible scenarios is that the chondrule precursor dust particles are heated and melt in the high-velocity rarefied ...

Abstract— Isotopic compositions and abundances of boron were measured in sixteen chondrules from seven chondrites by ion microprobe mass spectrometry. The chondrules are of the porphyritic, barred, and radial type and host meteorites include carbonaceous, ordinary, and enstatite chondrites.

Annual Review of Earth and Planetary Sciences, 1997
▪ Abstract Chondrules are ∼1-mm igneous droplets in primitive meteorites, and their abundance suggests widespread melting in the protoplanetary disk. Chondrules with relict unmelted grains or igneous rims record multi111ple melting events. There are two main types of chondrules, type I (FeO-poor and volatile-poor) and type II [FeO-rich and ...

Meteoritics, 1970
Very small chondrules, which are less than 250μ in size and are referred to as microchondrules, were discovered in twelve chondritic meteorites. The morphology, composition, and structure of these microchondritic bodies are investigated. In particular, the description of the principal, minor, and accessory minerals is given in some detail ...
