Timber management of coastal watersheds in southwest Oregon has
been complicated by the need to protect anadromous fish habitat from
accelerated stream sedimentation resulting from management activity.
The rugged terrain of the Elk and Sixes River basins is underlain by
the complex geological province of the Klamath Mountains, in which...

AN ABSTRACT OF THE THESIS OF
Margaret H. McHugh for the degree of Master of Science in
Paleozoic dolomites, limestones, and detrital clastic rocks
were mapped in the Bellevue Peak 15 minute quadrangle in the
southern Mahogany Hills, Nevada. Sedimentary rock units in this
area represent shallow-shelf eastern assemblage deposits.
Shallow-shelf carbonates characterized deposition from at
least Ordovician through Late Devonian time, when clastics derived
from the...

AN ABSTRACT OF THE THESIS OF
Robert Allen Schalla for the degree of Master of
Subduction zone earthquake and tsunami hazards affect tens of millions worldwide and the recurrence of these disasters can be evaluated with paleoseismic techniques, because earthquake cycles (and their supercycles) typically span many millennia. In these three chapters, I discuss a suite of analyses I use to evaluate the sedimentary record...

The thesis area consists of 42 square miles located
in Madison and Gallatin counties, Montana, in the southern
part of the Madison Range. The strata exposed in the
area range in age from Precambrian to Quaternary and have
an aggregate thickness of more than 7,600 feet.
The Paleozoic rocks, about...

The purpose of this study was to test two hypotheses. The first
hypothesis interprets allochthonous rocks in the Willow Creek area of the
Pinyon Range as lying on flat, superficial thrusts that truncate the
underlying folded Mississippian rocks of the Antler flysch sequence.
The second hypothesis interprets the allochthonous rocks...

A THESIS
submitted to
The oldest strata present in the Swales Mountain area
are part of the Roberts Mountains allochthon. These include
the western-facies Ordovician Vinini Formation and unnamed
transitional-facies Devonian limestones. The Vinini Formation
comprises dark cherts and black to brown shales
deposited in a deep-water oceanic environment. The Devonian
limestones include numerous...
