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 and use of N isotopes as tracers of fluid-rock
processes
- N incorporation into cyclosilicates (beryl,
cordierite)
- N-C behavior during metasedimentary partial
melting in the
continental crust
(w/ Ian Buick, Univ.
Stellenbosch; see abstract for
2008 Goldschmidt Conference)
- deep subduction of N as expressed in phengite
concentration and isotope composition
(w/ Ralf Halama, Kiel Univ., and
Timm
John, Univ. Norway, Oslo)
- microbial activity in modern and ancient seafloor
basalts
(w/ Neil Banerjee, Univ. W. Ontario)
- N behavior/cycling in Archean sedimentary suites
(w/ Linda
Godfrey, Rutgers)
- N record of fluid flow in Karoo Basin, South
Africa (w/
Henrik Svensen, Univ. Norway, Oslo)
C
and N
isotopes in reconstruction of recent paleoclimate, tree rings, lake
sediments
(w/ Zicheng Yu,
Lehigh University; Robert Moeller, Miami University, Ohio)
-
White Lake, New Jersey (Li et al., GCA, 2008), high-resolution work by
Cheng Zhao)
- Kepler and Reed Lakes, Alaska (work done by Andrew
Gonyo)
Synorogenic
fluid flow
in the Idaho-Montana and Appalachian thrust belts
- Idaho-Montana thrust belt, w/ David 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)
ODP Leg 185,
Izu-Bonin-Mariana Margin, Leg 205, Central America
(N-C in subducting sediment and oceanic crust; S. J. Sadofsky,
Long Li; Sadofsky and
Bebout, 2004, G-cubed; Li and Bebout,
2005, JGR;
Li and Bebout, 2006, ODP SR)
