Academic Interests and Accomplishments |
Dr. Guccione's current research has been focused in two general areas. First, the
evolution of bedrock-incised valleys in the Ozark and Ouachita Mountains. This includes
the migration, incision, and aggradation of stream channels and the sedimentation
and geomorphology of valley floors. Second, Dr. Guccione studies stream response to
internal and external variables in alluvial valleys. This includes response of the
Mississippi River to subtle neotectonic deformation in the New Madrid seismic zone,
channel migration, cutoffs, and avulsions, and backswamp sedimentation. Nearly all
of her research has been collaborative with archeologists.
For the past three summers Dr. Guccione has been working with undergraduate and graduate
students who are mapping near McCartney Mountain in southwest Montana under the auspices
of the US Geological Survey EDMAP program. Though the major emphasis has been on
the Tertiary and Quaternary gravels, the students have mapped:
Archean metamorphic rocks - Paleozoic cratonic sedimentary rocks and Mesozoic foreland
basin rocks that have been folded, thrust faulted, and intruded by Cretaceous granodiorite
Tertiary intrusive and extrusive rocks associated with Cenozoic extension and gravels
that have filled the resulting basins
Each year the students have gone to the Ar39/Ar40 lab at the US Geological Survey in Reston, VA to prepare for radiometric dating the
basalt, rhyolite, volcanic ash, and volcanic tuff samples that they collected while
mapping earlier in the summer.
