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...

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...

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 the silicate phase of pallasitic meteorites

Creator:: Cooper, Thurman Dale
Abstract:: The silicate phases of 11 pallasites were analyzed instrumentally to determine the concentrations of some major, minor, and trace elements. The silicate phases were found to contain about 98% olivine with 1 to 2% accessory minerals such as lawrencite, schreibersite, troilite, chromite, and farringtonite present. The trace element concentrations, except...

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...

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,...

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...

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....
Resource Type:: Masters Thesis

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...
