chondrite

The Y/Ho values of the samples from the yellow bauxite (YB) are almost close to those of chondrite which vary from 24 to 34 (Bau, 1996).

Chondrite normalized values cited from Sun and McDonough, 1989.

"Therefore, this likely implies that carbonaceous chondrite organics were formed through chemical reactions in the early Solar System, rather than having been inherited from the interstellar medium."

Effect of different chondrites on the parameter of rare-earth elements: and the theory of chondrite meteorites standard.

The information compiled on ordinary chondrites indicates that these meteorites originate from small asteroids which, with a diameter of less than a few hundred kilometres, collided, giving rise to these rocks millions of years ago.

Overall light REE enrichment and relatively flat heavy REE abundances relative to chondrites in the Litchfield pluton (Fig.

The LILE and HFSE data of the studied diorites are normalized to chondrite and plotted on the spider diagram (Fig.

Amino acids themselves are formed by all sorts of abiotic reactions (as witness their presence in things like carbonaceous chondrite meteorite fragments).

The studied rocks, which are normalized according to chondrite and primitive mantle, are illustrated in figures 6.

Analysis showed that the rock was a common type known as a "chondrite" - the kind most likely to cause a major extinction event in the future.

The reflectance spectrum was rather featureless and of an unusually low slope, consistent with the object's being similar to a carbonaceous chondrite meteorite of type CO or CV.

[1] infer an initial [sup.36]Cl/[sup.35]Cl ratio of > 1.6 x [10.sup.-4] in sodalite from the carbonaceous chondrite Ningqiang based on Al-Mg systematics.

Cosher cosecant promiscuously charactron chondrite ?

Analysis of the meteorites, known as EET92042 and GRA95229, showed that they contained the highest levels of amino acids ever found in a chondrite.
