We are upgrading the repository! We will continue our upgrade in February 2025 - we have taken a break from the upgrade to open some collections for end-of-semester submission. The MS-GIST Master's Reports, SBE Senior Capstones, IPLP dissertations, and UA Faculty Publications collections are currently open for submission. Please reach out to repository@u.library.arizona.edu with your questions, or if you are a UA affiliate who needs to make content available in another collection.

dc.description	The Sullivan Buttes Latite is an intermediate, high-potassium volcanic rock located in the Transition Zone geologic province of central Arizona. The latite outcrops in Chino Valley, along the southwestern border of the Colorado Plateau. Lava flows, volcaniclastic deposits, and intrusive bodies of latite are found in the Chino Valley area (Tyner 1984). Radiometric dates of 21 to 27 Ma have been obtained from the latite, placing them in the Upper Oligocene to Lower Miocene (Nealey and Sheridan 1989). The latite is of interest as it contains a distinctive xenolith suite. The suite includes eclogite, amphibolite, clinopyroxenite, garnet websterite, granulite, and spinel peridotite (Nealey and Sheridan 1989). Xenocrysts of pyroxene, amphibole, plagioclase and quartz are common in the latite (Tyner 1984), and have been interpreted as originating in the lower crust to upper mantle. The xenoliths have been the subject of considerable study, including work by Arculus and Smith (1979); Schulze and Helmstaedt (1979); and Tyner and Smith (1986). The latite was characterized chemically and petrographically in detail by Tyner (1984), who was able to identify six distinct units within the latite on the basis of geochemistry and mineralogy. These units are amphibole, amphibole-biotite, biotite-pyroxene, mafic, basaltic, and upper latite.
