The essential process in continuous casting is cooling and solidification of the cast medium during heat loss across a slip surface followed by extrusion from a mold. There are implications here for the manner in which core complexes form.

This open-file report describes the carbon-sequestration potential at the site of the 1 Alpine-Federal geothermal test drill hole, which is located south of Springerville in central eastern Arizona near the New Mexico border. A previous report, Arizona Geological Survey (AZGS) Open-File Report OFR 94-1, version 2.0, describes the subsurface geology encountered in the 1 Alpine-Federal well in much more detail than this new report.

The purpose of this research project is to determine the origin of the materials used to construct the Black Hills Dam in order to restore the landscape to pre-dam conditions. The Black Hills Dam site is located in northern Scottsdale, Maricopa County, at 33.75° North, 111.80° West. The goals of this project are to characterize the surficial deposits and local geology of the dam site. This report presents our findings, interpretations and conclusions based on background research, a site visit to the dam site, and technical discussions with the City of Scottsdale engineer and planners.

The goal of this study is to develop a method for identifying potential post-fire debris flow hazard areas prior to the occurrence of wildfires, providing more time for local governments and emergency planners to develop and execute hazard mitigation strategies. This pilot study focuses on the communities of Pine and Strawberry, which are located in forested canyons at the base of the Mogollon Rim in north-central Arizona. Results from this project will provide local agencies, emergency planners and land managers more effective tools for prioritizing watershed treatment areas and implementing mitigation measures to alleviate potential impacts and threats from post-fire ...

In order to begin to assess debris‐flow hazards along the Santa Catalina Mountains in Pima County, we mapped the extent and character of relatively young prehistoric debris‐flow deposits in detail at fifteen canyon mouths. Mapping was conducted on a scale of 1:6,000 using aerial photographs, detailed topography, and field relationships. Deposits were classified into relative age categories based on topographic relationships, soil development and surface characteristics of the deposits. Ages of selected debris‐flow deposits in four canyons – Soldier, Sabino, Finger Rock and Pima – were estimated using radiocarbon (14C) and cosmogenic (10Be) isotope methods. Evidence of past debris flows ...

This field trip guide was created for a Project WET conference held in Tucson, Arizona, June, 2007. This guide discusses the general geology of the Santa Catalina Mountains in Sabino Canyon, and points out evidence of the July 2006 floods and debris flows. There are stops in the first few miles of canyon, and towards the end of the tram road, where the most spectacular debris flows are located.

Throughout the southwestern United States, vegetation in what historically was grassland has changed to a mixture of trees and shrubs; exotic grass species and undesirable shrubs have also invaded the grasslands at the expense of native grasses. The availability and amount of soil nutrients influence the relative success of plants, but few studies have examined fire effects on soil characteristics in a temporal, spatial, and species group-specific fashion. Likewise, few studies have tied fire effects and ecological aspects to the underlying geology. Our research investigates the effects of fire events on selected soil characteristics pH, nitrate (NO3-), plant-available phosphorus (PO4-3), ...

Seven sinkholes surround the city of Sedona in Coconino and Yavapai Counties, Arizona. They occur in surface bedrock of Permian age Esplanade Sandstone, Hermit formation, and Schnebly Hill Sandstone, but the causative source is from the collapse of subsurface water-filled caves in Mississippian Redwall Limestone that underlies those formations. The original Mississippian-age Redwall karst surface has undergone two additional phases of dissolution enlargement in later geologic time. The first occurred after the Laramide uplift of the Mogollon Highlands when northeast flowing streams penetrated the exposed Redwall Limestone erosion surface, and the second took place following the generation of the Verde ...

At the request of the U.S. Forest Service to Red Rock Jeep Tours of Sedona a geologic report on the condition of the Devils Kitchen sinkhole was required for the safe continuation of Jeep visits to the site (Fig. 1). Mark Avery of the jeep company contacted me to study the site and write up my findings. The study of sinkholes in the Sedona area has been of interest to the writer for some time and the present study is hoped to shed some light on these fascinating geologic features. This report is offered as a public contribution at the ...

A brief reconnaissance (5-8 November 2008) of the Big Sandy Formation near Wikieup (on US Highway 93 in Mohave County, Arizona) was undertaken to reconcile a reported dominance of lacustrine beds (Sheppard and Gude, 1972, 1973) with the largely terrestrial mammalian fauna reported from the formation (MacFadden et al., 1979; Lindsay and Mead, 2005). The issue is resolved satisfactorily by appreciation that nearly all fossil localities occur in fluvial beds that intertongue with and grade laterally into the dominant lacustrine strata.

The State And Local Arizona Documents (SALAD) collection contains documents published by the State of Arizona, its Counties, incorporated Cities or Towns, or affiliated Councils of Government; documents produced under the auspices of a state or local agency, board, commission or department, including reports made to these units; and Salt River Project, a licensed municipality. ASU is a primary collector of state publications and makes a concerted effort to acquire and catalog most materials published by state and local governmental agencies.

The ASU Digital Repository provides access to digital SALAD publications, however the ASU Libraries’ non-digitized Arizona documents can be searched through the ASU Libraries Catalog and Library One Search. For additional assistance, Ask A Government Documents Librarian.

Publications issued by the Morrison Institute for Public Programs at Arizona State University are available in the ASU Digital Repository Morrison Institute for Public Policy - Publications Archive collection.
