OPPORTUNITIES
FOR NEW
GRADUATE STUDENTS
Some Ongoing
Projects Involving
Stable Isotopes
Experimentation
with methods for determining N isotope compositions of silicates
(carrier gas methods, laser extractions; contact G. E.
Bebout, B. D. Idleman)
Biogeochemical
cycling of N, use of N isotopes as tracers of high-T fluid-rock
processes
- N incorporation into cyclosilicates (beryl,
cordierite)
- organic C-N behavior during partial melting in the
continental crust
- deep subduction of N as expressed in phengite
concentration and isotope composition
Use of C and N
isotopes in reconstruction of recent paleoclimate, tree rings, lake
sediments
(New Jersey, Pennsylvania, Alaska; with Zicheng Yu,
Lehigh University)
Synorogenic
fluid flow
in the Idaho-Montana and Appalachian thrust belts
- Idaho-Montana thrust belt, with David J. Anastasio, Adrienne Rygel,
recent
M.S.
student,
Lehigh University (see Anastasio
et al.,
2004, AJS; Rygel et
al., 2006,
Geofluids)
- Appalachians, W. Virginia, with Mark Evans, Central Connecticut
State University, and
Carolyn Brown,recent M.S. student, Lehigh
University
(and Lehigh
undergraduate
students involved in the LEO Isotope
Hydrogeology Station)
Shorebased
research for ODP, Leg 185,
Izu-Bonin-Mariana Margin, Leg 205, Central America
(N-C budgets in subducting sediment and oceanic crust; S. J. Sadofsky,
Long Li; see Sadofsky
and Bebout, 2004, G-cubed; Li and Bebout,
2005, JGR;
Li and Bebout, 2006, ODP Leg
25 SR)
