The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

The electrical conductivity of Atlantic type pyromagmas from Mount Etna, SicilyMathews, Frank Samuel 18 July 1969 (has links)
The electrical conductivity of the pyromagmas from the Northeast
Crater of Mount Etna, Sicily was measured over the temperature
range 1032°C to 1071°C and over the frequency range 1 kHz to
400 kHz. Measurements were made using a four-terminal Wenner
array in conjunction with a Wavetek Model 110B portable signal generator
and Hewlett Packard Model 731 portable electronic voltmeters.
The electrical conductivity is of the order of 0.4 mhos/m with
less than 20% dispersion over the frequency range. Over the 40
degree temperature interval the temperature coefficient of resistance
corresponds to an activation energy of 1.5 ± 0.5 eV. The value for
the electrical conductivity of the gas-charged pyromagma is related
to values determined in the laboratory for gas-free melts of lava and
for glasses and slags of similar chemical composition. An original
design of semi-expendable graphite-molybdenum electrode
contributed greatly to the reliability of the measurements.
A chromatographic analysis of the vent gases, and a silicate
analysis, a modal analysis and a normal analysis of the lavas are
included for completeness. Finally, as an aid to future electromagnetic
probing activity, an analysis and estimate are made of the variation
of electrical conductivity of pyromagma with depth in a volcanic
conduit. / Graduation date: 1970
