The group A3 chondrules of Krymka: Further evidence for major evaporative loss during the formation of chondrules [PDF]

, 1993
Like Semarkona (type 3.0), Krymka (type 3.1) contains two distinct types of chondrule (namely groups A and B) which differ in their bulk compositions, phase compositions, and CL properties.

Shape, size, and distribution of magnetic particles in Bjurbole chondrules [PDF]

, 1994
Chondrules from the Bjurbole chondritic meteorite (L4) exhibit saturation remanence magnetization (SIRM) values which vary over three orders of magnitude.

Scanning electron microscopy characterization of iron, nickel and sulfur in chondrules from the Allende meteorite – further evidence for between-chondrules major compositional differences

Revista Mexicana de Ciencias Geológicas, 2014
En este trabajo se analiza la distribución espacial y los contenidos relativos de hierro (Fe), níquel (Ni) y azufre (S) en condros individuales separados de un fragmento del meteorito Allende, por medio de observaciones y análisis con microscopía ...

Adhesive growth and abrasion of chondrules during the accretion process [PDF]

, 1986
P(論文)Droplet chondrules are classified into three groups based on the surface features. The group A chondrules, common in the equilibrated chondrites, do not have a clear boundary with the matrix. The ambiguity of the surfaces of group A can be explained

Two spinel-bearing compound chondrules from the Baszkówka meteorite [PDF]

, 2001
The present paper describes two compound chondrules labelled panda and chevron, discovered in the Baszkówka meteorite. Optical microscope, electron microscope and electron microprobe studies revealed an unusual mineral composition and fabric.

Petrology of chondrules in ALH-77015 (L3) chondrite [PDF]

, 1981
P(論文)Chondrules in ALH-77015 (L3) chondrite were studied petrographically. Size and bulk chemical composition of about one hundred chondrules were investigated with relation to their texture. There seems to be no relation between the size and the texture,

Forming the Noncarbonaceous Chondrite Parent Bodies in the Presence of the Jupiter Barrier

The Astrophysical Journal
Meteorites can be divided into two groups—noncarbonaceous chondrite like (NC) and carbonaceous chondrite like (CC)—with distinct stable-isotope compositions. Parent bodies of NC and CC meteorites have overlapping formation ages. This suggests they formed

Young Stellar Object Jets Magnetocentrifugally Driven by Reconnecting Atmospheric Avalanche Accretion Streams above Inner Circumstellar Disks

The Astrophysical Journal
Fast, collimated jets are ubiquitous features of young stellar objects. They are generally thought to be powered by disk accretion, but the details are debated.

Texture of chondrules

Texture of chondrules
P(論文) Textures of chondrules in the unequilibrated ordinary chondrites have been summarized on the basis of the processes of their formation inferred from the results of previous experiments. The chondrules studied are classified by their textures into the following four groups : (1) those formed by complete melting of the precursor materials, (2 ...
