Research Interests
|
Newberry Caldera,
Oregon, USA
|
- Tephrochronology, the
use of volcanic ash (tephra) layers to provide
correlations between sites and age control -
including:
- analytical methods
for obtaining geochemical data (e.g. electron
microprobe, ICP-MS), including the development
of new procedures and new standard reference
materials
- cryptotephra
(locating and identifying trace volcanic ash
that does not occur as visible layers),
especially in glacial ice
- applications (e.g.
Quaternary geology, climate change,
paleolimnology, archaeology, paleoseismology)
- Volcanology &
petrology, especially of pyroclastic rocks -
including:
- Proximal
stratigraphy and geochemistry
- Eruption and
depositional mechanisms (from deposit
characteristics such as particle size variations
and thickness distributions)
- Dispersal patterns
related to wind
