“…This anomaly of 300-400 gamma maximum amplitude correlates with hornblende -biotite granitic rocks cutting the northern part of the Kettle gneiss dome (Fox, 1983, personal commun.). The magnetic expression of these rocks is consistent with the observations of Cady and Fox (1983) who suggest that hornblende-biotite granites produce local magnetic highs in a regional magnetic pattern of low magnetic relief.…”

“…A large uranium geochemical anomaly lies within Kettle gneiss dome rocks in the eastern part of the Seventeenmile Mountain and the western part of the Twin Lakes quadrangles. Specifically, the uranium anomaly is associated with biotite (muscovite) granitic gneiss (unit "gg" of Fox, 1983, unpublished map), which confirms Cady and Fox's (1983) conclusion that such granitic rocks can contain significant uranium and could therefore be the source for undiscovered uranium deposits in nearby suitable host rocks.…”

“…Enrichment of magnetite in biotite-muscovite granitic rocks causing magnetic highs may be indictive of source rocks for possible uranium deposits as suggested by Cady and Fox (1983).…”

“…In a regional study of potential field geophysical data (gravity and magnetics) of the gneiss terrane of northern Washington and southern British Columbia, Cady and Fox (1983) indicate that the Omineca Crystalline Belt is characterized by a broad regional gravity high marked by local gravity highs associated with individual gneiss domes. While, the latter part of the above statement may indeed be true in broad regional terms, detail gravity data presented by Sherrard and Flanigan (1986) suggest that the Kettle gneiss dome may be a notable exception.…”

“…Rocks exposed in this area form the principle part of the Kettle Gneiss Dome; they include biotite (muscovite) granite, granitic gneiss and protolithic rocks consisting of biotite schist, quartzite, marble and phyllites (Fox, 1983 andHolder, 1983, unpublished maps).…”

VllNorthern California through Oregon and Washington to British Columbia. The intellectual scope was as broad and interdisciplinary as possible, with participants representing the fields of geology, heat flow, seismology, igneous petrology, hydrology, electromagnetic geophysics, magnetics, water geochemistry, gravity, paleomagnetism, and tectonics.The conference was organized around three major themes:Variations in tectonics, geophysical signature, and magmatism along the length of the Cascade volcanic arc.Relationship of the Cascade Range to the subduction tectonics to the west and to the continental tectonics to the east. Controls on the location, composition, and rates of magmatism in the Cascade Range. The 35 attendees were almost equally divided between USGS scientists and scientists from other research institutions, including universities, other federal agencies, state agencies, Canada, and Japan.This Redbook contains nearly all the presentations made at the 01-04 December 1988 Conference in Monterey. We do not intend or imply that it is the final word on the Cascade Range.Instead, its purpose is to release promptly the material presented at the December 01-04 Conference to other concerned investigators and to the public.Accordingly, we have not attempted to edit the contributions, even lightly. It is our plan, however, that each of the authors will revise his/her Redbook contribution in view of the other contributions and that the resultant papers will form the nucleus of a reviewed and edited special section of the Journal of Geophysical Research, hopefully to be published within the year.
