Area of Study

STATEMAP is a matching fund program involving the US Geological Survey and State Geological Surveys that supports geologic mapping at the quadrangle (1:24,000) scale. The Arizona Survey's involvement with STATEMAP began in 1993 and continues today. Over the past 25 years, AZGS has received ~ $4,000,000 in federal funds, which are matched dollar-for-dollar by state funds.  AZGS has produced more than 160 geologic maps as part of the STATEMAP program.

Phil Pearthree, (AZGS Director) lays out details of AZGS STATEMAP Program - 2017 in the Arizona Geology e-News Magazine, Summer 2017 issue.

    Using LiDAR to view geologic features, San Francisco volcanic field

    The USGS previously mapped the bedrock and Tertiary and Quaternary volcanic stratigraphy in the Flagstaff area. With STATEMAP support, AZGS geologists Ann Youberg and Jeri Young-Ben Horin are investigating the alluvium and geohazards – flooding, debris flows and earthquakes. The LiDAR images below, one displaying bedrock geology, and the second with geographic annotation are informing the mapping. AZGS' focus is on the light gray areas adjacent to the volcanics. These data will require revisioning of some of the bedrock contacts, and the same topo data with 10m contours. USGS's Kyle House is assisting with building out slope maps to better image the topography. The lidar data is a game changer. (A. Youberg & JY. Ben Horin)

    US Bureau of Mines documents @ AZGS Repository

    US Bureau of Mines’ reports specific to Arizona are being stockpiled at the AZGS Online Document Repository for ease of access for our Arizona stakeholders. This includes USBM’s Information Circulars (I.C., 32 reports ), Report of Investigation (R.I., 8 reports) and Mineral Land Assessment (MLA, 84 reports) reports.

    Brad Johnson joins San Diego State Univ. Alumni in E AZ

    AZGS' Brad Johnson joined San Diego State University Geology Alumni in the northern Dome Rock Mountains, Arizona, and the southern Big Maria Mountains, California. The two ranges contain Proterozoic basement rocks and highly deformed metamorphic correlatives of Grand Canyon Paleozoic sedimentary rocks. The effects of heterogeneous distributed shear on these rocks is most impressive.

    IMAGE. View to the east of part of a north-dipping, overturned, highly attenuated fold limb in the Big Maria Mountains. The person on the left is standing on the unconformity between Proterozoic granitoid rocks (to viewer's left) and the Cambrian Tapeats quartzite. Between there and the other person is the entire Cambrian section consisting of Tapeats, Bright Angel schist, and Muav marble.
    The person on the right is standing on Devonian dolomitic marble. The resistant brown ledge in the lower right corner of the photo, and continuing in the distance behind that person, is the Pennsylvanian-Permian Supai Group. The Mississippian Redwall marble forms a 1-meter-thick white ledge just above the Supai. Photo by George Morgan.

    Vintage report on uranium-vanadium in NE Arizona

    While not a STATEMAP product, we just released (2/27/18) a vintage report by William Chenoweth on uranium-vanadium mineral production in northeastern-most Arizona. Title of the 24-page report, ' The Geology and Production History of the Uranium- Vanadium Mines on Plot 6, West Reservation Lease, and on Hoslie Henry’s Mining Permits, Northwestern Carrizo Mountains, Apache County, Arizona.  You can view and download the report at http://repository.azgs.az.gov/uri_gin/azgs/dlio/1746 .
