New geologic mapping from the Cedar Mountains - Bloody Basin - Cooks Mesa area in the central Arizona Transition Zone presents an enigmatic geologic relationship that has previously gone unstudied. Here, fault blocks of Early Proterozoic basement overlain by Tertiary sedimentary and tuffaceous-lacustrine deposits and capped by a thick accumulation of basalt flows, dated in the project area between 15.1 and 13.5 Ma, are rotated ~20o west to west-southwest along east-dipping normal faults.
Topics include land use, demographics, specific industry sectors, the role of non-labor income, the wildland-urban interface, the role of amenities in economic development, and payments to county governments from federal lands.
Phase I Environmental Site Assessment (ESA) for Dripping Springs, a property comprised of approximately 160 acres located in Sections 7 and 8 of Township 4 South, Range 15 East, Gila and Pinal Counties, Arizona.
This technical memorandum has been prepared to document results and analysis of a 23-day aquifer test conducted at hydrologic test well HRES-09. M&A conducted the long-term test to provide aquifer parameters for the Apache Leap Tuff (ALT) aquifer in the area of the well.
This technical memorandum presents the results from the 43-week extended kinetic geochemical characterization program of scavenger tailings for the Resolution Copper Project conducted by Golder Associates (Golder). The program was carried out to evaluate the environmental stability of the tailings and supplement the static testing program reported in Golder 2007.
The GoldSim contaminant transport module provides capabilities for simulating chemical processes such as partitioning and solubilities. While flexible and easily configurable, these simple processes do not represent complete reaction paths, hence additional chemical relationships are sometimes needed to model complex hydrochemical systems. A versatile approach for representing complex chemical processes of chemical equilibration and aqueous speciation is to rely on GoldSim’s dynamic link library (DLL) element.
