DEPARTMENT OF THE INTERIOR U.S. FISH AND WILDLIFE SERVICE REGION 2 DIVISION OF ENVIRONMENTAL CONTAMINANTS CONTAMINANTS IN BIGHORN SHEEP ON THE KOFA NATIONAL WIL DLIFE REFUGE, 2000-2001 By Carrie H. Marr, Anthony L. Velasco1, and Ron Kearns2 U.S. Fish and Wildlife Service Arizona Ecological Services Office 2321 W. Royal Palm Road, Suite 103 Phoenix, Arizona 85021 August 2004 2 ABSTRACT Soils of abandoned mines on the Kofa National Wildlife Refuge (KNWR) are contaminated with arsenic, barium, mercury, manganese, lead, and zinc. Previous studies have shown that trace element and metal concentrations in bats were elevated above threshold concentrations. High trace element and metal concentrations in bats suggested that bighorn sheep also may be exposed to these contaminants when using abandoned mines as resting areas. We found evidence of bighorn sheep use, bighorn sheep carcasses, and scat in several abandoned mines. To determine whether bighorn sheep are exposed to, and are accumulating hazardous levels of metals while using abandoned mines, we collected soil samples, as well as scat and bone samples when available. We compared mine soil concentrations to Arizona non-residential clean up levels. Hazard quotients were elevated in several mines and elevated for manganese in one Sheep Tank Mine sample. We analyzed bighorn sheep tissues for trace elements. We obtained blood, liver, and bone samples from hunter-harvested bighorn in 2000 and 2001. Arizona Game and Fish Department also collected blood from bighorn during a translocation operation in 2001. Iron and magnesium were elevated in tissues compared to reference literature concentrations in other species. Most often, domestic sheep baseline levels were used for comparison because of limited available data for bighorn sheep. -

Orocopia Schist in the Northern Plomosa Mountains, West-Central Arizona: a Laramide Subduction Complex Exhumed in a Miocene Metamorphic Core Complex
RESEARCH Orocopia Schist in the northern Plomosa Mountains, west-central Arizona: A Laramide subduction complex exhumed in a Miocene metamorphic core complex E.D. Strickland1, J.S. Singleton1, and G.B. Haxel2,3 1DEPARTMENT OF GEOSCIENCES, COLORADO STATE UNIVERSITY, FORT COLLINS, COLORADO 80523, USA 2U.S. GEOLOGICAL SURVEY, FLAGSTAFF, ARIZONA 86001, USA 3GEOLOGY PROGRAM, SCHOOL OF EARTH SCIENCES AND ENVIRONMENTAL SUSTAINABILITY, NORTHERN ARIZONA UNIVERSITY, FLAGSTAFF, ARIZONA 86011, USA ABSTRACT We document field relationships, petrography, and geochemistry of a newly identified exposure of Orocopia Schist, a Laramide subduction complex, in the northern Plomosa Mountains metamorphic core complex of west-central Arizona (USA). This core complex is character- ized by pervasive mylonitic fabrics associated with early Miocene intrusions. The quartzofeldspathic Orocopia Schist records top-to-the-NE mylonitization throughout its entire ~2–3 km structural thickness and 10 km2 of exposure in the footwall of the top-to-the-NE Plomosa detachment fault. The schist of the northern Plomosa Mountains locally contains graphitic plagioclase poikiloblasts and scattered coarse- grained actinolitite pods, both of which are characteristic of the Orocopia and related schists. Actinolitite pods are high in Mg, Ni, and Cr, and are interpreted as metasomatized peridotite—an association observed in Orocopia Schist at nearby Cemetery Ridge. A 3.5-km-long unit of amphibolite with minor interlayered ferromanganiferous quartzite is localized along a SE-dipping contact between the Orocopia Schist and gneiss. Based on their lithologic and geochemical characteristics, we interpret the amphibolite and quartzite as metabasalt and meta chert, respectively. The top of the Orocopia Schist is only ~3–4 km below a ca. -
Gold Deposits Near Quartzsite, Arizona
GOLD DEPOSITS NEAR QUARTZSITE, ARIZONA. By EDWARD L. JONES, Jr. INTRODUCTION. This report is based on information obtained by the writer in April and May, 1914,. while he was classifying the lands in the Colorado River Indian Reservation. The area considered includes the south ern part of the reservation and the region extending eastward from the reservation to the Plomosa Mountains. The geology and ore deposits within the reservation were more particularly studied, the time allotted to the examination being too short to permit detailed work in the area farther east. For information concerning placers outside the reservation the writer is indebted to Mr. E. L. Du- fourcq, who conducted the testing of placer .ground near Quartz- site. Mr. W. W. McCoy, of San Bernardino, kindly furnished the early history of the La Paz district, and Mr. Edward Beggs, of Quartzsite, gave much useful information regarding the La Paz placers. In 1909 Howland Bancroft x made a geologic reconnaissance of northern Yuma County .and much of the country around Quartz- site and farther west to the reservation line. In his report he men tions the La Paz district and briefly describes placers in the Plomosa Mountains and prospects on gold-bearing quartz veins in the vicinity of Quartzsite. The map that accompanies the present report (PI. IV) is compiled from the records of the General Land Office. The area within the reservation has been subdivided into sections; the land east of the reservation is unsurveyed. The mountainous areas in the reserva tion are indicated on this map by patterns showing the geologic rock formations; the mountains in the unsurveyed area are repre sented approximately by hachures. -

Pull-Apart Basins at Releasing Bends of the Sinistral Late Jurassic Mojave-Sonora Fault System
spe393-03 page 97 Geological Society of America Special Paper 393 2005 Pull-apart basins at releasing bends of the sinistral Late Jurassic Mojave-Sonora fault system Thomas H. Anderson* Department of Geology and Planetary Science, University of Pittsburgh, Pittsburgh, Pennsylvania 15260, USA Jonathan A. Nourse Geological Sciences Department, California State Polytechnic University, Pomona, California 91768, USA ABSTRACT A 200–500-km-wide belt along the southwestern margin of cratonic North America is pervaded by northwest- and east-trending faults that fl ank basins con- taining thick deposits of locally derived conglomerate and sedimentary breccia. These deposits that crop out mainly in the northern part of mainland Mexico, or southern parts of Arizona and New Mexico are unconformable at their bases, have similar Upper Jurassic and/or Lower Cretaceous stratigraphic ages, and commonly preserve volcanic components in the lower parts of upward-fi ning sections. We argue that these basins share a common structural origin, based on: (1) the presence of faults, locally preserved, that generally defi ne the basin margins, (2) similar basal units comprised of coarse conglomeratic strata derived from adjacent basement, and (3) locally preserved syntectonic relationships to bounding faults. Fault orientations, and our observation that the faults (and their associated basins) extend south to the inferred trace of the Late Jurassic Mojave-Sonora megashear, suggest that the basins formed in response to transtension associated with sinistral movement along the megashear. Northwest-striking left-lateral strike-slip faults that terminate at east-striking normal faults defi ne releasing left steps at which crustal pull-apart structures formed. -

This system was originally recognized by aprons of coarse, arkosic sandstone and conglomerate within the Paradox, Eagle, and Denver Basins, which surround the Front Range and Uncompahgre basement uplifts. However, substantial portions of Ancestral Rocky Mountain–adjacent basins are filled with carbonate or fine-grained quartzose material that is distinct from proximal arkosic rocks, and detrital zircon data from basins adjacent to the Ancestral Rocky Moun- tains have been interpreted to indicate that a substantial proportion of their clastic sediment was sourced from the Appalachian and/or Arctic orogenic belts and transported over long distances across Laurentia into Ancestral Rocky Mountain basins. In this study, we pres- ent new U-Pb detrital zircon data from 72 samples from strata within the Denver Basin, Eagle Basin, Paradox Basin, northern Arizona shelf, Pedregosa Basin, and Keeler–Lone Pine Basin spanning ~50 m.y. -
