Research interests:
Dr. Foit’s research interests are focused in three areas : tephrochronology
of the Pacific Northwest, the crystal chemistry of sulfosalts and
the tourmaline group of rock forming minerals and the shock effects on
minerals of large meteorite impact. Field and laboratory studies
of the age, distribution, and stratigraphy of tephras are useful in the
dating of archaeological sites, unraveling paleoclimatic events as recorded
in the sedimentary record and understanding the hazards posed by PNW volcanoes. The
principle tool used in these investigations is the electron microprobe
microanalyzer (EPMA). Much of this research is interdisciplinary
in nature and involves collaborations with archaeologists, forest
biologists, paleoclimatologists to name a few. He also uses
the EPMA to study the diverse elemental substitutions in the tetrahedrite
group of sulfosalts and the tourmaline group. Tetrahedrite group
minerals are a major source of Cu and Ag as well as a potential petrogenetic
indicators. With NASA support Foit in collaboration with M.
Pope and A.J. Watkinson and their student are examining quartz and carbonates
from a large impact structure using X-ray diffraction and microprobe analysis
to better understand and quantify the shock pressure regime they
were subjected to.
