The Alaska Division of Geological & Geophysical Surveys (DGGS) has conducted 1:63,360-scale geologic mapping of the Eagle A-1 Quadrangle. The area is part of the 100-year old Fortymile mining district and is located in eastern Alaska near the Alaska-Yukon border. This map illustrates potential near-surface sources of various geologic materials that may be useful for construction. Field observations indicate that each geologic unit (for example, stream alluvium) has a definite composition or range of composition. Therefore, the probable presence of materials is interpreted from the distribution of geologic units on the geologic map of this quadrangle. This map is generalized and is not intended to show exact locations...

This study encompasses the whole of the Oracle Junction 7.5' quadrangle and the eastern third of the Tortolita Mountains 7.5' quadrangle (see figure 1). Late Tertiary basin-fill deposits and younger Quaternary surficial deposits dominate most of the region and are well-exposed along the length of Oro Valley. The western third or so is underlain by a broad, flat pediment on the east side of the Tortolita Mountains. The pediment was etched into Proterozoic and Tertiary granitic rocks and is punctuated by more resistant hills of Pinal Schist and an east-northeast-trending band of younger metasedimentary rocks. Middle and Late Pleistocene sandstones and conglomerates lap up onto the pediment. These deposits contain...

The Oracle 7.5' Quadrangle is located approximately 40 km north-northeast of downtown Tucson, and is on the northwest flank of Santa Catalina Mountains (Figure 1). The quadrangle encompasses the northwestern comer of the range, some of the flanking pediment around the town of Oracle, and alluvium in northeastern Oro Valley. The area was mapped during October 1999 to April 2000 as part of a multiyear mapping program directed at producing complete geologic map coverage for the Phoenix-Tucson metropolitan corridor. A 1 :24,000 scale map is the primary product of this study (Plate 1). This map incorporates past mapping by other workers as well new mapping by the authors (Figure 2). The accompanying report describes...

The Samaniego Hills are a low series of hills composed of flat-lying to gentlydipping early Miocene and possibly late Oligocene lava flows interbedded with thin units of volcaniclastic and locally non-volcaniclastic sandstone and conglomerate. The preserved sequence is approximately 600 meters thick. The top is not preserved, but the base is well exposed along the southern edge of the hills, where it overlaps K-feldspar porphyritic granite of probable Middle Proterozoic age invaded by diabase dikes. The diabase occurs as vertical and subhorizontal dikes, and is probably associated with the Middle Proterozoic Apache Group, which overlies the granite sparingly along the southern edge of the map area. The granitic...

The Picture Mountain quadrangle is centered on the southwest flank of the Sierra Ancha (see Figure 1). The geology of the area is dominated by the middle Proterozoic Apache Group and the diabase that intrudes it, and some extensive middle Tertiary conglomerates. Elevations range from about 2800 feet in the southwest comer of the map to 6610 feet at Bear Head Mountain. Vegetation. In response to the change in elevation the vegetation changes dramatically across the study area. Saguaro and Palo Verde dominate the lowest elevations in the southwest, with many varieties of cacti. The mid-elevations in the central part of the map contain a mix of open Pinyon-Juniper forest and grassland and thick stands of scrub oak....
