Chemical and statistical analyses of chondrules from the Mokoia (CV3) meteorite

Creator:: Schilk, Alan J.
Abstract:: Nearly 100 chondrules were extracted from -8.6g of the Mokoia (CV3) meteorite and have been analyzed by sequential instrumental neutron activation analysis (INAA). The resulting data were utilized in a comprehensive statistical characterization of these objects and, unlike similar investigations, virtually no loss of relevant data was incurred due to...

Analysis of fourteen trace elements in Saudi Arabian layered gabbros by radiochemical neutron activation analysis

Creator:: Palmer, Curtis Allyn
Abstract:: Eight layered gabbro samples from two layered complexes, two xenoliths, one basalt from a hot brine area and a standard basalt rock (BCR-1) were analyzed by RNAA (radiochemical neutron activation analysis) for 14 trace elements, Au, Ni, Co, Ag, Sb, Se, Zn, In, T1, Rb, Cs, U, Ba and Sr....

The chemical composition of 61 individual Allende chondrules

Creator:: Warren, Richard Gregory
Abstract:: The abundances of 12 elements, Fe, A1, Na, Ni, Cr, Mn, Co, Ca, Sc, Ir, Sm and Eu have been determined by INAA in 61 individual chondrules (0.1-100 mg) separated from five Allende (C3) meteoritic fragments ( 25g). Ti and V have been determined in 18 of these chondrules, and...

A study of the chemical composition of Ca-Al-rich inclusions from the Allende Meteorite

Creator:: Conard, Roberta
Abstract:: Nine Ca-Al-rich inclusions and one olivine inclusion from Allende meteorite were studied for Ti, Al, Fe, Mg, Ca, Na, Cl, K, Sc, V, Cr, Mn, Co, Ni, Zn,Hf, W, Ir, Au, Ta, and Re -via INAA (instrumental neutron activation analysis) and REE, Ba, Sr via RNAA (radiochemical NAA). The inclusions...

Chemical compositional studies of marginal rift and plateau basalts from Saudi Arabia

Creator:: Coles, D. G.
Abstract:: The analysis of 64 rock samples from Saudi Arabia and three samples from the axial trough of the Red Sea has been done. Instrumental neutron activation analysis (INAA) was the analytical tool used for the analysis of at least 18 and as many as 24 elements in these 67 rock...

Elemental abundances in meteoritic chondrules

Creator:: Osborn, Thomas Ward, III
Abstract:: High-precision instrumental neutron activation analysis has been used to determine Al, Na, Mn, Sc, Cr, Fe, Co, and Ni in a suite of more than 500 chondrules from 26 distinct meteorites. These meteorite specimens represent the H, L, LL and C chemical classes and most of the petrologic types. In...

A chemical and petrological study of igneous lithic clasts from the kapoeta howardite

Creator:: Smith, Monty Ray
Abstract:: Instrumental and radiochemical neutron activation analyses supported by electron microprobe mineral analyses (Paul Warren, University of New Mexico) and petrographic observations are presented for approximately forty individual clasts separated from the Kapoeta howardite. These clasts are classified into eucritic, cumulate-like, mafic (plagioclase ± olivine-bearing pyroxenites), pyroxenite, polymict and/or metal-rich and...
Resource Type:: Dissertation

Chemical element profiles by instrumental neutron activation analysis : in, part 1, two species of wheat bunt spores, Tilletia caries (DC) Tul. and Tilletia controversa Kühn; part 2, representative sediment and basalt samples taken from a DSDP 678 m core, site 525A, Leg 74, Walvis Ridge

Creator:: Liu, Yun-gang
Abstract:: Part 1 The concentration of seventeen elements in two species of fungus which cause wheat bunt disease, Tilletia caries (DC.)Tul. (TS) and Tilletia controversa Kiihn (DS), were determined by instrumental neutron activation analysis in 37 TS spore samples, and 31 DS spore samples. Aluminum was chosen as a soil contamination...

Sodium and manganese homogeneity in chondritic meteorites

Creator:: Osborn, Thomas Ward, III.
Abstract:: Four to six one-gram specimens separated by a distance of several inches were obtained from each of 23 large chondritic meteorites (approximately 1 kg each) representing the olivine bronzite (H5), olivine hypersthene (L6) and enstatite (E5) classifications. Each specimen was analyzed for Na and Mn via instrumental neutron activation analysis...
