Karen Harpp: Other Projects

Research in Antarctica

Origin of the Vanda Dike Swarm, Dry Valleys, Antarctica

Through geochemical, petrologic, and geochronologic analyses coupled with field observations, we are attempting to understand the origin of the dike swarm in the Dry Valleys of Antarctica that occurred approimately 500 million years ago. We believe it may represent the transition between a convergent and divergent tectonic setting, and may as a result be able to inform us further about the nature of that tectonic rearrangement. This is a collaborative study between Colgate, the University of Hawaii, and the University of Idaho. It is funded by the National Science Foundation.

Research in Ecuador

Boiling-Over Pyroclastic Flows at Tungurahua and Cotopai Volcanoes, Ecuador

Using a multi-disciplinary approach that combines geochemical analysis, paleomagnetism, granulometry, and numerical modeling, we are investigating the origins of boiling-over pyroclastic flows. These phenomena are poorly understood, occurring suddenly and without warning at several volcanoes today including Tungurahua. This is a collaborative project between Colgate, the University of Idaho, and the Georgia Institute of Technology. It is funded by the National Science Foundation.
