Geochimica Et Cosmochimica Acta, 1992 The origin of isolated olivine grains in carbonaceous chondrites has been suggested to be either by direct condensation or by fragmentation of chondrules. In an attempt to resolve this debate, isolated olivine grains in the carbonaceous chondrite ALHA77307 have been studied in detail.

Oxygen Isotopic Composition of Relict Olivine Grains in Cosmic Spherules: Links to Chondrules From Carbonaceous Chondrites [PDF]
Geochimica Et Cosmochimica Acta, 2015 Most olivine relict grains in cosmic spherules selected for the present study are pristine and have not been disturbed during their atmospheric entry, thereby preserving their chemical, mineralogical and isotopic compositions.

Primitive Grain Clumps and Organic Compounds in Carbonaceous Chondrites
Nature, 1976WE show here that the physical conditions in prestellar molecular clouds favour the condensation of complex organic polymers, including amino acids, within a matrix of smaller refractory particles. Such composite grain clumps with dimensions exceeding 1 µm could be expelled along with gaseous material in protostellar cocoons, causing the widespread ...

Laboratory Experiments on the Low-Temperature Formation of Carbonaceous Grains in the ISM [PDF]
Astrophysical Journal, Supplement Series, 2017 Abstract The life cycle of cosmic dust grains is far from being understood and the origin and evolution of interstellar medium (ISM) grains is still under debate. In the ISM, the cosmic dust destruction rate is faster than the production rate by stellar sources.

Nanosized Carbon-Rich Grains in Carbonaceous Chondrite Meteorites
Earth and Planetary Science Letters, 2004Abstract Macromolecular carbonaceous material is common in primitive meteorites. Little information exists on its form and composition, and there are no published data on nanometer-scale chemical and structural variations. Transmission electron microscopy (TEM) studies of CM meteorites reveal abundant, previously unrecognized nanosized carbonaceous ...

Grain Size and Petrography of C2 and C3 Carbonaceous Chondrites
Meteoritics, 1978Grain size frequency distributions of the ≥ 0.1 mm size fractions have been measured for 19 C2 and C3 carbonaceous chondrites (7 CM2, 5 CO3, 6 CV3 and 1 CV2). The grain size frequency distribution curves and summary statistics are remarkably similar for the CM2 and CO3 meteorites, with ranges of median grain size from 2.36φ to 2.67φ and graphic mean ...
