Copper homogeneity studies in meteorites

Creator:: Wong, Dennis Tung
Abstract:: The abundance of copper was determined in four to six one-gram specimens separated by a distance of several inches from each of 23 large chondritic fragments (greater than 1 kg) via instrumental neutron activation analysis and counting of the annihilation N-rays of ⁶⁴Cu. It is believed that an accuracy of...

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...

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...

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....

Variations in trace element abundances in small fragments from a single terrestrial basaltic flow : applications to 59 Apollo-17 mare basaltic fragments

Creator:: Rivera, Maria Rita Dacanay
Abstract:: Eleven hand specimen whole rock (WR) samples (25-200 g each) and 33 fragments (0.5-0.8 g each) from a single basaltic flow at Picture Gorge, Oregon were analyzed via instrumental neutron activation analysis (INAA) for 12 elements (Na, Fe, Cr, Sc, Co, La, Sm, Eu, Yb, Lu, Hf and Ta). Standard...

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...
Resource Type:: Masters Thesis
Full Text:: half-dram polyvial, which was empty, was placed into the 2- dram polyvial on top of the sample vial

Elemental abundances in selected Oregon basalts

Creator:: Nicholson, Barry Howard
Abstract:: Ninety basalt samples from eight locations in central Oregon and one location in the Willamette Valley were analyzed for Si and Al. Fourteen basaltic rock specimens (> 1 kg each) from four buttes in the Willamette Valley were sampled and analyzed for Si, Al, Fe, Na, K, Mn, Cr, Co,...

A chemical study of the minerals from L-6 chondritic meteorites

Creator:: Curtis, David Ballantyne
Abstract:: Major and minor minerals have been separated from three L-6 chondritic meteorites (Alfianello, Colby (Wisconsin), and Leedey). Olivine, hypersthene, diopside, feldspar, troilite, chromite, phosphate minerals, and metallic minerals were analyzed for major, minor and trace elements using instrumental neutron activation analysis and radiochemical neutron activation analysis techniques. Concentrations df the...

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...
