Chlorine Distribution In The Idaho Batholith, Laurence Stewart Istas Nov 1976

Chlorine Distribution In The Idaho Batholith, Laurence Stewart Istas

Dissertations and Theses

Chlorine is thought to play a major role in the mobilization and concentration of base metals in the formation of ore deposits. The regional distribution of chlorine in the Idaho Batholith was studied to see if this could be related to mineralization or metallic provinces. One hundred forty-eight whole-rock samples, mineral separates, and standards were analyzed for chlorine by x-ray fluorescence.

The expected concentration of chlorine in the biotite fraction was not found. The chlorine was not significantly water leachable from the whole rock samples following normal grinding. The Idaho Batholith as a source for mineralizing chlorine was not established. …


Biostratigraphy Of The Snowshoe Formation (Jurassic) In The Izee Area, Grant County, Oregon, Paul Lawrence Smith Aug 1976

Biostratigraphy Of The Snowshoe Formation (Jurassic) In The Izee Area, Grant County, Oregon, Paul Lawrence Smith

Dissertations and Theses

Using the standard Jurassic zonal scheme, this work attempts to determine the ages of the four members of the Snowshoe Formation that crop out in the Izee area. As a corollary, regional correlations are possible. The stratigraphic relationship between the Snowshoe Formation, the subjacent Hyde Formation and the superjacent Trowbridge Formation is also investigated.

Over one thousand fossils were collected from five stratigraphic sections and eight localities. The sections were measured using tape and compass techniques and the relative stratigraphic ranges of the fossils calculated using a computer program written specifically for this project. The ammonite fauna, dominated by the …


Electrical Conductivity Of Thin Lecithin-Cholesterol Membranes Due To 2,4-D, 2,4-Db, 2,4,5-T And 2,4-Dcp, Malkanthi Paulis Jul 1976

Electrical Conductivity Of Thin Lecithin-Cholesterol Membranes Due To 2,4-D, 2,4-Db, 2,4,5-T And 2,4-Dcp, Malkanthi Paulis

Dissertations and Theses

The effect of the following pesticides on DC electrical conductivity of lecithin-cholesterol membranes has been studied: endothall, paraquat, diquat, 2,4-D, 2,4-DB, 2,4,5-T, 2,4-DCP. It has been found that the ions of endothall, paraquat and diquat are essentially membrane impermeable and that they do not bind to the membrane surface. In contrast, 2,4-D, 2,4-DB, 2,4,5-T and 2,4-DCP induce electrical conductivity in lecithincholesterol membranes and in addition they also cause an increase in the nonactin-K+ membrane conductivity.

The compounds 2,4-D, 2,4-DB, 2,4,5-T and 2,4-DCP basically behave as class II uncouplers. The kinetic scheme of charge transfer across the membrane, based on …


Stratigraphy, Structure, And Petrology Of The Snoqualmie Pass Area, Washington, Lawrence A. Chitwood Jul 1976

Stratigraphy, Structure, And Petrology Of The Snoqualmie Pass Area, Washington, Lawrence A. Chitwood

Dissertations and Theses

The Snoqualmie pass area lies about 50 mi (80 km) east of Seattle, Washington, along the crest of the Cascade Range. Five stratified units, forming a composite section over 22,000 ft (6700 m) thick, are recognized in the area. They were deformed and later intruded by granodiorite and quartz monzonite porphyry of the Snoqualmie batholith (middle Miocene). The oldest unit, the Denny Formation (Permian), 7000 ft (2100 m) thick, consists of interstratified basalt, andesite and dacite volcanic rocks and limestone and chert beds. This formation is unconformably overlain by a thick conformable sequence of early Tertiary strata which are subdivided, …


The Addition Of Sf5br To Unsaturated Systems, Qui-Chee Wendy Wang Jun 1976

The Addition Of Sf5br To Unsaturated Systems, Qui-Chee Wendy Wang

Dissertations and Theses

Addition reactions of pentafluorosulfur bromide with unsaturated substrates were studied and four new compounds containing the pentafluorosulfur group have been prepared.

The mechanism for these reactions seems to involve a radical addition pathway. In reaction with CH2=CFC1, CF3C≡CH and CH3C≡CH the SF5 radical attacks the carbon atoms carrying the most hydrogens. The reaction with CF2=CHCl is interesting, as by analogy with other fluoroolefins, the SF5 primary attack should occur.at the CHCl group, however, SF5CF2CHC1Br was found as the only product for this reaction. The reaction of …


Debye–Hückel Theory For Rigid‐Dipole Fluids, John D. Ramshaw May 1976

Debye–Hückel Theory For Rigid‐Dipole Fluids, John D. Ramshaw

Physics Faculty Publications and Presentations

The dipolar analog of classical linearized Debye–Hückel theory is formulated for a finite fluid system of arbitrary shape composed of rigid polar molecules. In contrast to the ionic case, the dipolar Debye–Hückel (DDH) theory is nonunique due to an inherent arbitrariness in the choice of a local field E*. This nonuniqueness is expressed in terms of a parameter ϑ related to the ellipticity of the spheroidal cavity used to define E*. The theory then leads to an expression for the direct correlation function c (ϑ) as a function of ϑ. Only the short‐range part of c (ϑ) depends upon ϑ; …


The Geology Of The Castle Rock Area, Grant, Harney And Malheur Counties, Oregon, John David Wood Apr 1976

The Geology Of The Castle Rock Area, Grant, Harney And Malheur Counties, Oregon, John David Wood

Dissertations and Theses

The geology of the Castle Rock area aids in the understanding of Cenozoic volcanic stratigraphy and structures in an area where these volcanic rocks thin near the margins of the pre-Tertiary basement rocks and structural trends are overlapping. The Castle Rock area is unique in several aspects and is important in understanding and interpreting the geology in adjacent regions which have all been studied, at least on a regional basis. Intrusive ash-flow bodies of the Dinner Creek Ash-Flow Tuff, well-exposed sections of complexly interstratified volcanic rocks and well-exposed faults, and of high amount of erosional relief are features which make …


The Chemistry Of Chromium (Vi) And Chromium (V) Oxide Fluorides, Patrick Jay Green Apr 1976

The Chemistry Of Chromium (Vi) And Chromium (V) Oxide Fluorides, Patrick Jay Green

Dissertations and Theses

New preparative routes to chromyl fluoride were sought. It was found that chlorine monofluoride reacts with chromium trioxide and chromyl chloride to produce chromyl fluoride. Attempts were made to define a mechanism for the reaction of ClF and Cr03 in light of by-products observed and previous investigations. Carbonyl fluoride and chromium trioxide react to form chromyl fluoride and carbon dioxide. A mechanism was also proposed for this reaction. Chromium trioxide with MoF6 or WF6 reacts to produce chromyl fluoride and the respective oxide tetrafluoride.


Structural Geology Of The Northeast Quarter Of The Dutchman Butte Quadrangle, Southwest Oregon, Rauno K. Perttu Apr 1976

Structural Geology Of The Northeast Quarter Of The Dutchman Butte Quadrangle, Southwest Oregon, Rauno K. Perttu

Dissertations and Theses

The northeast quarter of the Dutchman Butte quadrangle straddles the boundary of the Mesozoic Klamath Mountains province and the Tertiary Coast Range province. The boundary in this area is controlled by a major easttrending fault zone, herein named the Canyonville fault zone. Jurassic Rogue, Dothan, and Otter Point Formations have been offset right-laterally at least 40 kilometers. In latest Jurassic and early Cretaceous time, the fault zone formed the shoreline along which sediments of the Myrtle Group were deposited.

Movement on the Canyonville fault zone becale down-to-the-north in Eocene time forming the southern margin of the Eocene Coast Range basin. …


The Effect Of A Magnetic Field On The Leclanché Cell, Walter Edward Socha Mar 1976

The Effect Of A Magnetic Field On The Leclanché Cell, Walter Edward Socha

Dissertations and Theses

The effect of a magnetic field on an electrochemical system, the Leclanche cell, was investigated. Experiments show that there is an increase power output and charge passed when a cell is discharged in an applied magnetic field.

Possible explanations for the effect and descriptions of attempts to verify these explanations are presented.

Polymerization Of Amino Acids On Kaolinite, Z. Badri Adnani-Gleason Jan 1976

Polymerization Of Amino Acids On Kaolinite, Z. Badri Adnani-Gleason

Dissertations and Theses

In the origin of life on the primitive earth a major step must have involved the condensation of amino acids to form the first polypeptides. Several suggestions as to how this might have occurred have been made by other workers. One of the more appealing proposals is that the polymerization was catalyzed by clay minerals. It has been reported, for example, that L-apartic acid polymerizes significantly faster than D-aspartic in the presence of kaolinite in aqueous suspension at 90˚. In this work an attempt was made to repeat this report and extend the pH range to include values presumably present …


Geology Of The Breitenbush Hot Springs Area, Cascade Range, Oregon, Clifford Michael Clayton Jan 1976

Geology Of The Breitenbush Hot Springs Area, Cascade Range, Oregon, Clifford Michael Clayton

Dissertations and Theses

The Breitenbush Hot Springs area lies on the boundary of folded middle to late Tertiary Western Cascade rocks and younger High Cascade rocks. Within the mapped area the Western Cascade rocks are represented by four formations. The Detroit Beds, a sequence of interstratified tuffaceous sandstone, mudflow breccia, and tuff, is overlain unconformably by the Breitenbush Tuff. The Breitenbush Tuff consists of three units of welded pumice-rich crystal-vitric ash-flow tuffs interbedded with tuffaceous sedimentary rocks. The Outerson Formation unconformably overlies the Breitenbush Tuff and consists primarily of basaltic lava and breccia.

The Outerson Formation includes three localized members: a basal, glassy, …
