A sequence of soils derived from tuffaceous rocks was sampled
on the H. J. Andrews Experimental Forest and adjacent U. S. Plywood
land to determine some genetic and stability relationships. The
less than two micron size fraction from each sample was characterized
by x-ray diffraction with respect to crystalline clay...
A study was conducted to evaluate the properties of soils in
the fog belt area of the Oregon Coast Range. Soils in the study
were chosen to include only those belonging to Andepts or to andic
subgroups. Samples were collected from eleven sites that were
formed mostly from colluvial deposits...
An intensive chemical investigation, that includes the
determinations of salinity, oxygen, nutrients, pH, alkalinity, and
total carbon dioxide of the Columbia River plume off the Oregon
coast in July 1967 shows the following unique features:
1. Along the axis of the river plume both the salinity minimum and
temperature maximum...
Based on the principle that the history of a discipline is important to the discipline itself, this thesis devotes two chapters to ROBERT HOOKE AND THE FOUNDATION OF GEOLOGY and two chapters to modern geology, viz. THE TECTONIC EVOLUTION OF THE OREGON CONTINENTAL MARGIN. The first part of this abstract...
