Petrochemical patterns in young pillow basalts dredged from Juan de Fuca and Gorda Ridges

Creator:: Wakeham, Susan E.
Resource Type:: Masters Thesis
Full Text:: basalt, even though they may have already undergone limited olivine fractionation since their formation

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,...

Geochemical study of Hawaiian basalts

Creator:: Budahn, James Richard
Resource Type:: Masters Thesis
Full Text:: processes involved in the evolution of Hawaiian magmas. Comparison of basalt compositions having similar

Chemical composition studies of Oregon and Washington coastal basalts

Creator:: Hill, Dale Wayne
Abstract:: Basalts of both Eocene and Miocene age from several groups along the Oregon and Washington coasts have been analyzed for some major, minor, and trace elements using instrumental neutron activation analysis (INAA). The rare earth element (REE) patterns observed in these samples are used for comparisons within the groups studied...

Feeder dikes to the Columbia River flood basalts : underpinnings of a large igneous province

Creator:: Petcovic, Heather L.
Abstract:: Feeder dikes to the Columbia River Basalt Group (CRBG) large igneous province provide a rare opportunity to examine magma transport through the shallow crust during flood basalt eruptions. Over 70% of the CRBG erupted from the Chief Joseph dike swarm, which is exposed across southeastern Washington, eastern Oregon, and western...

The Ore Bin ; Vol. 38 No. 11 (November 1976)

Creator:: Oregon. Dept. of Geology and Mineral Industries, Farooqui, Saleem M., and Heinrichs, Donald F.
Abstract:: The Columbia River Basalt consists of dozens of seemingly identical flows of basalt covering thousands of square miles of Oregon, Washington, and Idaho. For years, detailed mapping of the units relied almost entirely on subtle petrographic distinctions, the presence or absence of interbeds, and actual walking along contacts in the...

Geochemical evolution of the Roseburg formation basaltic rocks, southern Oregon coast range

Creator:: Pyle, Douglas G.
Abstract:: The Paleocene-lower Eocene volcanic rocks of the southern Oregon Coast Range Roseburg Formation are the oldest remnant eruptive sequence of an oceanic islandseamount province which is presently exposed along a north-south lineament that stretches from Vancouver, B.C. into southwestern Oregon. This seamount terrane is thought to have formed on the...

The Southeast Indian Ridge water contents of MORB glasses and chemical effects of propagating rifts

Creator:: Sylvander, Brendan A.
Resource Type:: Masters Thesis
Full Text:: understanding of H2O in mid-ocean ridge basalt (MORB) lavas is important because, while H2O is a minor

Magmatic processes at mid-ocean ridges : evidence from lavas and melt inclusions from the Southeast Indian Ridge, the Endeavour Segment of the Juan de Fuca Ridge, and the northern East Pacific Rise

Creator:: Sours-Page, Rachel E.
Abstract:: Magmatic processes control the chemical compositions of all lavas erupted at mid-ocean ridges. In this thesis, I present studies of magmatic processes on three different mid-ocean ridges to determine which processes are in action and to what extent each has affected the chemistry of mid-ocean ridge basalts at each location....
