Welcome to the location with links to download the latest cross-platform, web enabled versions of the Dynamic Digital Map of the Springerville Volcanic Field (DDM-SVF). The Springerville is a late Pliocene to Holocene basaltic volcanic field located in east-central Arizona. It is dominated by over 400 mapped cinder cones and associated lava flows. The DDM displays nine thematic geologic maps of the field, 234 images and QuickTime movies (many aerial and from NASA's World Wind satellite), over 577 major and trace element whole-rock chemical analyses, mineral chemistry for 31 units, paleomagnetic polarity data from >180 sites, ~ 40 K-Ar dates, and Sr, Nd and Pb istopic analyses, all linked to sample sites located on the maps and in some of the photos. The DDM also includes three articles, each with numerous hyperlinks to the maps and images. The first is an introduction to the geology of the field, and to the map and mapping conventions. The other two are field trip guides. The first of the guides is a modified version of the 1989 IAVCEI field trip which concentrates on the petrology of the field; it contains hyperlinks to icons of field trip stops, displayed on the lithologic map. The second guide concentrates more on the volcanologic and tectonic features of the field.
A Guided Tour button on the lower right side of the Home Screen will give you an automated tour of the program, in the form of a nine-minute scripted playback, introducing you to the basics of how to use a DDM.
