"Dehydrated" chondrules from the Murchison (CM) chondrite [PDF]
, 1996 P(論文)Two "dehydrated" chondrules (MC-5 and MC-27) were obtained from close to the fusion crust of the Murchison (CM) meteorite. They have a porphyritic texture with angular or rounded (relict) olivines containing abundant voids, recrystallized olivines ...

Experimental Reproduction of Olivine rich Type-I Chondrules [PDF]
, 2005 Ordinary chondritic meteorites are an abundant type of stony meteorite characterized by the presence of chondrules. Chondrules are small spheres consisting of silicate, metal, and sulfide minerals that experienced melting in the nebula before ...

Tungsten Isotopes and the Origin of Chondrules and Chondrites [PDF]
, 2018 Chondrules and matrix from carbonaceous chondrites exhibit complementary nucleosynthetic W isotope anomalies that result from the depletion of a metallic s-process carrier in the chondrules, and the enrichment of this carrier in the matrix.

Synthesis of Si-Fe Chondrule-like Dust Analogues in RF Discharge Plasmas
Applied SciencesChondrules are tiny particles that occur in stony meteorites and are considered as the building blocks of early asteroids and planets. It is believed that they were formed by the fast heating of the dust in the solar nebula.
