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.
