NAVDAT and Geoinformatics

Much of my research is devoted to new ways to analyze large datasets of geochemical and geochronological data. I am involved in the ongoing development of NAVDAT, a database of geochemical and geochronological data from western North America. This effort, sponsored by the National Science Foundation, is collaborative with Doug Walker (University of Kansas) and Lang Farmer (University of Colorado).

Much of my effort in NAVDAT has been devoted to developing new ways to display data with animations. A library of examples is linked below.

   Coso volcanic field, 8 Ma to recent. Red is basalt, orange andesite and dacite, and yellow rhyolite.
Animation of western U.S. magmatism, 65 Ma to present
Polygon (geologic map) animation of the southwestern Basin and Range, 20 Ma to present. This animation was constructed largely by former grad student Austin Roelofs.
