Broad Research Areas

GPR Study, Wrightsville Beach, NCThe Department of Geography and Geology actively encourages and supports undergraduate and graduate student research. Our students participate in research projects covering many aspects of the geosciences. In the past, students have been involved in projects such as investigating hydrothermal venting at mid-ocean ridges, monitoring groundwater wells, studying ancient fossils of the southeastern coastal plain, reconstructing sea levels, mapping patterns of change in African savannas, and multiple other activities. Being a highly interdisciplinary department, we encourage interested undergraduate and graduate students to contact faculty members working in their research area of interest. Below, we list broad research areas faculty members in the department are involved in, followed by more specific research laboratories in our department. We welcome students with diverse interests: chances are, you will find your passion with us!

 

Specialized Research Laboratories

Basin Analysis Research Laboratory (BARL)

The Basin Analysis Research Laboratory (BARL), led by Dr. Todd LaMaskin, is an applied learning research lab that uses a wide array of tools to address problems in sedimentation, stratigraphy, tectonics, and geologic time in a broad theme of understanding the  evolution of sedimentary basins over time. Current research in the LaMaskin lab falls into two broad categories: (1) Using sedimentary provenance to understand the evolution of plate margins and continental sediment dispersal systems, and (2) Using stable isotope stratigraphy to establish a chronostratigraphic signature for the Late Triassic, Carnian-Norian Boundary interval. The lab maintains its primary workspace in the group-use Advanced Microscopy Laboratory, a 400 sq. ft facility housed in DeLoach Hall (RM 215). The Advanced Microscopy Laboratory is houses research-grade petrographic microscopes (Olympus BX-60 and Leica M165C with HD camera) and research-grade stereo microscopes (Leica DM2700P with attachable Leica DFC 450 camera and Leica DMEP). The lab also hosts a fume hood used for sodium polytungstate heavy mineral separation, a magnetic separator, light table, a sink and cabinets for storage. BARL researchers also routinely utilize workspace in the Clean Laboratory, the Geologic Materials Laboratory, Isotope Ratio Mass Spectrometer (IRMS) Laboratory, and Spatial Analysis Laboratory.

Kelley also directed (with Greg Dietl, Paleontological Research Institution) a Research Experiences for Undergraduates in Biodiversity Conservation program investigating paleoecological changes in the Plio-Pleistocene of the Carolinas (based on collections amounting to >75,000 mollusc specimens) as an analog for the modern biodiversity crisis.
