Lead isotopic concentration data collected from
detrital sediment from the Methow Basin. Data was
collected using a series of Pb leaching
techniques followed by a Multicollector-Inductivel
y Coupled Plasma Mass Spectrometer (MC-ICPMS).
Other isotopic concentrations were collected and
plotted, and will be compared to the batholith
data from the Peninsular Ranges Batholith to
determine the sediments potential source
location.

The most important feature is the variable
resistivity ocean, visible as the bright colors
along the edge of South America (the main blue
part of the image). My talk will discuss some of
the pros and cons of this style of ocean creation
versus a more topographically accurate ocean with
constant resistivity.

Each box is a velocity spectrogram from the same
seismic station for six nearly consecutive
volcanic explosions, where t0 is the time of the
explosion. The bright, upward "gliding" lines are
harmonic tremor, where the frequency of this
tremor increases from a few Hz to nearly 30 Hz in
the minutes before each explosion. The
repeatability and high frequency content of this
tremor is very unique, and has compelled us to
present an alternative to the commonly accepted
explanations for harmonic tremor on other
volcanoes.

Sr isotope ratio vs Th/U disequilibrium. 238U
decays to 230Th indirectly, and so the two
isotopes will stay at radioactive equilibrium if
left undisturbed (that is, n1?1 n2?2, or
(230Th/238U) 1). Disequilibrium results from
fractionation events such as partial melting, but
equilibrium is reestablished in about 5 half
lives (380,000 yr). The data suggest a
correlation between Sr isotope signature and
level of disequilibrium.

Cosmogenic radionuclide concentrations are a
function of exposure to cosmic rays and
radioactive decay.  Burial of a sample under ice
or sediment shields the sample from the incoming
cosmic-ray flux.  The ratio of 26Al to 10Be vs
10Be is plotted and contour lines indicate
exposure and burial time.  The half-lives of 26Al
and 10Be are 708 kyr and 1.36 Myr, respectively.
 The results of 5 cycles of exposure (20 kyr) and
burial (100 kyr) with no erosion are depicted by
the upper plot and the red line on the lower
plot.
