Spectral Properties Of Selfadjoint Ordinary Differential Operators With An Indefinite Weight Function, Branko Ćurgus, H. Langer

Mathematics Faculty Publications

Spectral properties of the equation l (f ) - λrf = 0 with an indefinite weight func­tion r are studied in L_I²rl . The main tool is the theory of definitizable operators in Krein spaces. Under special assumptions on the weight function, for the operator associated with the problem, the regularity of the critical point infinity is proved. Some relations to full- and half-range expansions are indicated.

History And Origin Of Debris Torrents In The Smith Creek Drainage, Whatcom County, Washington, Tim L. Syverson

WWU Graduate School Collection

Four debris torrent events have occurred in the Smith Creek drainage since the turn of the century. In 1917, 1949, 1971, and 1983, debris torrents transported large quantities of logs out of the basin onto the delta. Inventories of air photographs of the drainage before and after the three most recent events, combined with field observations after the 1983 event, show that debris torrents in the Smith Creek drainage are closely related to mass movements. Mass movements provide the momentum necessary to mobilize debris in stream channels during periods of heavy run-off, resulting in the formation of debris torrents. Debris …

The Geology And Structure Of The Canyon Creek-Church Mountain Area, North Cascades, Washington, Jeffrey T. (Jeffrey Thomas) Jones

WWU Graduate School Collection

Four major rock assemblages ranging from Precambrian to Lower Cretaceous occur in the Canyon Creek/Church Mountain area of northwestern Washington. Lithologic, structural, and fossil evidence were used to discriminate among the assemblages and to correlate them with the Chilliwack Group, the Nooksack Group, the Yellow Aster Complex, and a unit previously included in the Chilliwack Group, referred to here as the "chert/basalt unit." These assemblages were juxtaposed during middle Cretaceous tectonism along low angle and high angle faults. There is some evidence for additional structural deformation after the middle Cretaceous.

The Chilliwack Group, consisting of volcanic rocks, volcaniclastic rocks, and …

Paleomagnetism Of Four Late Cretaceous Plutons North Cascades, Washington, William J. (William James) Harrison

WWU Graduate School Collection

Paleomagnetic directions of samples from the Ten Peak and Sulphur Mtn. plutons, Hidden Lake stock, and Oval Peak batholith in the North Cascades reveal multi-component magnetization and instability. In the Hidden Lake stock and Ten Peak pluton, a strong viscous overprint parallels the present day field. The Sulphur Mountain pluton shows complete magnetic instability; making it impossible to compute a meaningful mean direction. The rocks of the Oval Peak batholith are believed to have been magnetically reset during the Eocene, although the observed declination of 167° and inclination of -67° is significantly different from the expected Eocene direction. The mean …

The Sedimentary Petrography, Depositional Environment And Tectonic Setting Of The Aldwell Formation, Northern Olympic Peninsula, Washington, Keith Marcott

WWU Graduate School Collection

The upper Eocene Aldwell Formation crops out in an east-west trending band across the northern Olympic Peninsula, Washington. Petrographic analyses indicate that the Aldwell Formation has lithologically distinctive eastern and western portions. The rocks of the eastern Aldwell are basalt-rich lithic greywackes; their mean compositions are Qm-F-Lt: 5- 22-73 and polycrystalline quartz-volcanic rock fragments-total sedimentary rock fragments: 1-78-21. The rocks of the western Aldwell are chert-rich lithic arenites; their mean compositions are Qm-F-Lt: 27-19-54 and polycrystalline quartz-volcanic rock fragments-total sedimentary rock fragments: 66-11-23.

Similarities in texture, composition, and alteration products suggest that the basalts of the Crescent seamount province as …

The Sedimentary Petrology And Sedimentology Of The Unnamed Middle Eocene Sandstones Of Scow Bay, Indian And Marrowstone Islands, Northwest Washington, Leslie A. Melim

WWU Graduate School Collection

The unnamed Middle Eocene sandstones of Scow Bay are well exposed on the beaches of Indian and Marrowstone Island, northwest Washington. The rocks strike approximately east-west and dip to the north except on the east coast of Marrowstone Island where the structure is more complex. Each of the four coastal sections was described in detail, and the most complete was also measured.

The sandstone beds are typically thin- to very-thick-bedded, structureless lithic arenite. Locally abundant sedimentary structures include dish structures, vague horizontal lamination, load casts, flame structures, soft sediment deformation, and shale clasts. Interbedded with the sandstones are minor siltstones …

Net Shore-Drift Of Kitsap County, Washington, Bruce E. Taggart

WWU Graduate School Collection

Kitsap County is located entirely within the Puget Sound Lowland in northwestern Washington State. It has a crenulated coastline 352 km in length. The Puget Sound Lowland, and Kitsap County in particular, is characterized by glacial landforms and sediments. Glacial activity is responsible for the shape and depth of the various water-bodies comprising Puget Sound, which is subject to mixed, semi-diurnal tides.

Net shore-drift is the process by which sediment, supplied to the margin of a landmass by subaerial and wave-induced erosional processes, is transported parallel to the coast by longshore drift and beach drift over a period of many …
