  • The Tectonic Evolution of the Madrean Archipelago and Its Impact on the Geoecology of the Sky Islands

    The Tectonic Evolution of the Madrean Archipelago and Its Impact on the Geoecology of the Sky Islands

    The Tectonic Evolution of the Madrean Archipelago and Its Impact on the Geoecology of the Sky Islands David Coblentz Earth and Environmental Sciences Division, Los Alamos National Laboratory, Los Alamos, NM Abstract—While the unique geographic location of the Sky Islands is well recognized as a primary factor for the elevated biodiversity of the region, its unique tectonic history is often overlooked. The mixing of tectonic environments is an important supplement to the mixing of flora and faunal regimes in contributing to the biodiversity of the Madrean Archipelago. The Sky Islands region is located near the actively deforming plate margin of the Western United States that has seen active and diverse tectonics spanning more than 300 million years, many aspects of which are preserved in the present-day geology. This tectonic history has played a fundamental role in the development and nature of the topography, bedrock geology, and soil distribution through the region that in turn are important factors for understanding the biodiversity. Consideration of the geologic and tectonic history of the Sky Islands also provides important insights into the “deep time” factors contributing to present-day biodiversity that fall outside the normal realm of human perception. in the North American Cordillera between the Sierra Madre Introduction Occidental and the Colorado Plateau – Southern Rocky The “Sky Island” region of the Madrean Archipelago (lo- Mountains (figure 1).

Central Campus Dr., Salt Lake City, UT 84112 3Utah Geological Survey, 1594 W. North Temple St., Salt Lake City, UT 84114 [email protected] Keywords: Sevier Thermal Belt, hydrothermal systems, heat flow, geochemistry, helium isotopes, stable isotopes. ABSTRACT The Sevier Thermal Belt, southwestern Utah, covers 20,000 km2, and it is located along the eastern edge of the Basin and Range, extending east into the transition zone of the Colorado Plateau. The belt encompasses the geothermal production fields at Cove Fort, Roosevelt Hot Springs, and Thermo, scattered hot spring activity, and the Covenant & Providence hydrocarbon fields. Regionally, it is characterized by elevated heat flow, modest seismicity, and Quaternary basalt-rhyolite magmatism. There are at least five large discrete domains (50 to >500 km2) with anomalous heat flow, including ones associated with Roosevelt Hot Springs, Cove Fort, Thermo and the Black Rock desert. Helium isotope data indicate connections to the upper mantle are developed over the region of strongest and most concentrated hydrothermal activity. By contrast, stable isotope data demonstrate that most of the convective heat transfer is associated with shallow to deep circulation of local meteoric water. Quartz-silica geothermometry suggests that convective heat transfer is compartmentalized by stratigraphic horizons and sub-vertical faults.
  • Chapter 3 of the State Wildlife Action Plan

    Chapter 3 of the State Wildlife Action Plan

    Colorado’s 2015 State Wildlife Action Plan Chapter 3: Habitats This chapter presents updated information on the distribution and condition of key habitats in Colorado. The habitat component of Colorado’s 2006 SWAP considered 41 land cover types from the Colorado GAP Analysis (Schrupp et al. 2000). Since then, the Southwest Regional GAP project (SWReGAP, USGS 2004) has produced updated land cover mapping using the U.S. National Vegetation Classification (NVC) names for terrestrial ecological systems. In the strictest sense, ecological systems are not equivalent to habitat types for wildlife. Ecological systems as defined in the NVC include both dynamic ecological processes and biogeophysical characteristics, in addition to the component species. However, the ecological systems as currently classified and mapped are closely aligned with the ways in which Colorado’s wildlife managers and conservation professionals think of, and manage for, habitats. Thus, for the purposes of the SWAP, references to the NVC systems should be interpreted as wildlife habitat in the general sense. Fifty-seven terrestrial ecological systems or altered land cover types mapped for SWReGAP have been categorized into 20 habitat types, and an additional nine aquatic habitats and seven “Other” habitat categories have been defined. SWAP habitat categories are listed in Table 4 (see Appendix C for the crosswalk of SWAP habitats with SWReGAP mapping units). Though nomenclature is slightly different in some cases, the revised habitat categories presented in this document
