About 435 mineral species have been identified in meteorites including native elements,
metals and metallic alloys, carbides, nitrides and oxynitrides, phosphides, silicides, sulfides …

In systematic searches for embryonic lethal mutants of Drosophila melanogaster we have
identified 15 loci which when mutated alter the segmental pattern of the larva. These loci …

Approximately 275 mineral species have been identified in meteorites, reflecting diverse
redox environments, and, in some cases, unusual nebular formation conditions. Anhydrous …

Thermal metamorphism has affected most chondritic meteorites to some extent, and in most
ordinary chondrites, some carbonaceous chondrites, and many enstatite chondrites it has …

Meteorite research is fundamental to our understanding of the origin and early history of the
Solar System. This book considers the mechanism and timing of core formation and basaltic …

A petrologic, geochemical and oxygen isotopic study of eight meteorites, identified as CR
(Renazzo-type) chondrites, reveals that they have a set of similar properties that …

Concentrations of 26 elements were determined by replicate neutron-activation analysis in
66 ordinary chondrites (22 H, 20 L, 17 LL, 2 intermediate between H and L and 5 …

A suite of 134 ordinary chondrites (OCs) was analyzed by electron microprobe to determine
olivine and kamacite compositions. Equilibrated members of the three main OC groups have …

Results Three plots of TL sensitivity against sample temperature I'glow curves'] are shown in
Fig. I, These three curves demonstrate the range of shapes observed, although most …

We describe three types of chondrules that are common to H3, LL3, CM2, CO3, and CV3
chondrites. Low and high‐FeO, porphyritic olivine chondrules contain olivine with Fa0. 3–8 …
