One group visited Southern Ohio to examine the late Ordovician paleontology and carbonate sedimentology. A second looked at geologic hazards along the southern coast of Lake Erie. Each student presented the results of their research in either a poster or an oral presentation. Highlights from many of the projects are given below. The Colorado Keck Project mapped the lithologies and structures of the eastern Wet Mountains.
Geochemistry suggests the basalts formed in a continental or island arc setting.
The rocks resemble rocks from the Yavapai terrane. On the Big Island of Hawai'i, Keck summer research students tackled a range of small but significant research projects developed in coordination with the USGS Hawaiian Volcano Observatory. Progress was made in understanding the origin or rare blue-glassy pahoehoe, the development of fault structure at Kilauea, the growth of Pu'u Ohau, a volcanic cone in Kona, the petrology of explosive ejecta from Halema'uma'u Crater, and a variety of other features. Work in McCall, Idaho showed that the impact of forest fires on stream nitrate concentrations was reduced in catchments having significant amounts of unconsolidated glacial sediments. A large quantity of new data on the chemistry of tourmaline from simple and complex pegmatites of southwestern Maine and from the metamorphic rocks in which they occur demonstrates that the chemistry of tourmaline is responsive to the environment of tourmaline growth and is thus a useful petrogenetic indicator.
