The abundances of the highly siderophile elements (HSE), Re, Os, Ir, Ru, Pt and Pd, were
determined by isotope dilution mass spectrometry for bulk samples of 13 carbonaceous …

The S (IV)‐type asteroid 6 Hebe is identified as the probable parent body of the H‐type
ordinary chondrites and of the IIE iron meteorites. The ordinary chondrites are the most …

The goal of classifying shock metamorphic features in meteorites is to estimate the
corresponding shock pressure conditions. However, the temperature variability of shock …

The compositions and textures of phases in eleven equilibrated ordinary chondrites from the
H, L, and LL groups spanning petrographic types 4–6 were studied and used to constrain …

We have performed petrologic and geochemical studies of Patuxent Range (PAT) 91501
and Lewis Cliff (LEW) 88663. PAT 91501, originally classified as an L7 chondrite, is rather a …

DaG 896 is an olivine-rich microporphyritic rock of komatiitic composition. Both the olivine
composition (Fa17. 5±2.1,[Mn/Mg]= 0.0061) and the bulk oxygen isotopic composition …

To examine compositional changes associated with high degrees of apparent thermal
metamorphism among the LL chondrites, we have examined seven LL chondrites originally …

A large impact event 500 Ma ago shocked and melted portions of the L‐chondrite parent
body. Chico is an impact melt breccia produced by this event. Sawn surfaces of this 105 kg …

The mineralogy, petrology, and geochemistry of an igneous-textured clast in the Peace
River L6 chondrite meteorite was examined to determine the roles of nebular processes …

To examine the thermal history of the parent body/bodies of equilibrated H chondrites, we
treated data for 11 volatile trace elements (Co, Rb, Ag, Se, Cs, Te, Zn, Cd, Bi, Tl, and In in …
