Proposal title: basaltic magmatic mapping of coyote hills shield volcano in the springerville volcanic field, east-central arizona project period: 01/01/2026 through 12/31/2026 purpose this project aims to map eruptive basalts of coyote hills shield volcano in the springerville volcanic field (SVF). The SVF is a well-mapped monogenetic volcanic field, with coyote hills being the only remaining unmapped area. This project aims to provide students with mapping and field experience while adding a very important last piece that will allow more work developing a petrogenetic model of the field, creating a complete picture of the volcanism; a picture that will be a rare glimpse of the entirety of a monogenetic volcanic field and will offer insights into hazard assessment and a template for studying similar fields. Activities one month of field work will be completed mapping and sampling the ~60 KM2 coyote hills shield volcano in the eastern extent of the SVF. Subsequent thin section and geochemical analysis will confirm and classify mapped volcanic units. The maps will then be digitized into lithologic maps accompanied by geochemistry and unit descriptions. Deliverables and outcomes two digital map, of the coyote hills shield volcano, one of the eastern portion and one of the western portion, in the springerville and coyote hills quadrangles, arizona (upper NW coordinates=34?16-00-, 109?10-55-, SE coordinates=34?07-32-, 109?10-08-; note the mapping area is confined to an irregular area directly in the coyote hills area contained within the coordinates given, the whole area within the coordinates will not be mapped). Maps will follow the geologic map schema (gems) standard. Accompanying unit descriptions for the mapped areas will be included. Intended beneficiary(IES) this work will train students in geologic mapping and provide them skills that will be invaluable to their futures as geologists, all while assessing a poorly understand style of eruption in a volcanic field. This field is currently having dates refined, and new ages suggest the younger flows are
