Ninety-five oriented samples were obtained from nine Recent
Cascade lava flows in Oregon. Directions and intensities of remanent
magnetization were measured on a spinner magnetometer which measures
directions of magnetization to within 1.2° s.d. Angle measurements
were plotted graphically using an equal area projection. Mean
directions and statistics were calculated...
Nearly 9,000 feet of Cretaceous mudstones, shales, sandstone,
and conglomerates are exposed along the northeast-trending Mitchell
anticline of central Oregon, These rocks are divided into two formations
on the basis of criteria developed in this investigation. The
lower formation, hereby designated the Meyers Formation, is 4,716
feet thick at its...
The purpose of this study was to determine if personality
traits relevant to creativity in adults are measurable in four year
old nursery school children. Instruments and scoring techniques
were developed to measure six specific traits. These traits are
the intellectual aptitude abilities of figural fluency, elaboration,
originality and penetration...
As colony-specific wintering ecology of small and medium-sized seabirds is poorly understood, it has been generally assumed that winter conditions have the same effect on all individuals from any given colony. However, advances in global positioning technology now allow researchers to investigate movements of smaller seabirds. We tracked black-legged kittiwakes...
In this memoir, by alumnus and Zoology Department instructor William J. Gilstrap, the author details various aspects of his life, including: childhood in Missouri, student experience at Oregon Agricultural College (OAC) in the 1890s, and his medical practice in various Oregon locales. Gilstrap also describes in this narrative the origins...
Major (Fe, Mn, Al) and minor (Cr, Mo, Pb, Zn, Cd) element
analyses of metalliferous sediments in cores from the East Pacific
Rise and Bauer Deep indicate that the Bauer Deep sediments are
similar in chemistry and origin to metalliferous sediments of the
East Pacific Rises.
Fe, Pb, and Zn...
The goals of this dissertation are centered on understanding changes in Earth surface and climate systems through the use of geologic proxies as records of past changes in these systems. Specifically, this dissertation (1) establishes a new chronology for retreat of the Ross Sea sector of the West Antarctic Ice...
