Research
Deep Time & Carbonate Rocks; Sedimentological and Stratigraphic Reconstruction of Ancient Environments and Climate, Diagenesis of Freshwater and Marine Limestones
My recent research on terrestrial carbonates spans the northern and southern hemispheres with field sites in Chile (Atacama Desert), Tanzania (Olduvai Gorge), and eastern North America (Nova Scotia to Georgia). The sedimentary strata range in age from Middle Cambrian (~503 Ma), to Triassic-Jurassic (~250-150 Ma), to Miocene-Pliocene (~5.3 Ma), to the Pleistocene (~2 Ma) and Holocene (thousands of years). My research integrates sedimentological and stratigraphic data to interpret depositional environments and paleoclimates, utilizing field study, petrography (stained thin sections, cathodoluminescence, Scanning Electron Microscopy), stable isotopes (carbon and oxygen), and elemental geochemistry (X-Ray Diffraction, Inductively Coupled Argon Plasma Spectrometry, Energy Dispersive SEM (EDAX)).
Miocene-Pliocene lake and wetland limestones, exposed in the Atacama Desert, indicate that carbonates may accumulate even during periods of aridity, as long as there is sufficient groundwater flow to feed a lacustrine/palustrine system and/or spring discharge, leading to tufa development (3 papers published, 1 in prep).
Freshwater limestones, with their particular sensitivity to climate, are excellent markers for distinctive depositional conditions. Triassic-Jurassic freshwater carbonates associated with the Newark Supergroup rift basins reflect periods of relative tectonic quiescence coupled with Milankovitch-scale wet-dry cycles (5 papers published).
Similarly, groundwater may circulate through regional faults to precipitate spring carbonates at discrete discharge sites or accumulate in marshy areas where groundwater seeps indicate topographic intersection with a shallow water table. These sites may have been a source of freshwater for Olduvai Gorge, Tanzania hominids in shallow lakes or ponds (4 papers published).
Marine shallow water limestones, may yield some paleoclimate information, at least in terms of arid vs humid climates, and tropical vs cool water temperatures. Evaporate minerals suggest a relatively arid climate where subaerial exposure of supratidal shoreline facies resulted in evaporite precipitation. The presence of early dolomite likely indicates a relatively warm and arid to semi-arid depositional setting, based on modern analogs. My research on marine limestones is also important in understanding burial processes and diagenetic alteration of primary carbonate (9 papers).
In addition to my geological research, I have been deeply involved with issues relating to Women in Science and Academic Leadership, based on my own experience and scholarship. For example, I have written about the value of shared or split academic positions for both an institution and a science couple (3 publications). I have also worked on the 鈥渢ime crunch鈥� women face in terms of the ticking biological and tenure clocks (1 paper), and most recently, my focus is on women in academic leadership roles (1 paper).
