Challenges For The New West: Economic Impacts Of Wilderness In Nevada's Rural Counties, Lesley Regina Argo Dec 2001

Challenges For The New West: Economic Impacts Of Wilderness In Nevada's Rural Counties, Lesley Regina Argo

UNLV Theses, Dissertations, Professional Papers, and Capstones

Public lands designated as part of the National Wilderness Preservation System are removed from multiple-use management for protection of their natural condition. Opponents argue that "locking up" the natural resources on these lands through designation will undermine the rural economies in the west that are dependent upon extractive industries such as mining and logging. Proponents argue that the "Old West" reliance on extractive industries is declining and, in the "New West", wilderness promotes economic development in rural communities by preserving the amenity values that draw population and employment to the region. Characteristics of Nevada's economy, population and land challenge the …


Structural And Geochemical Analyses Of Disseminated-Gold Deposits, Bald Mountain-Alligator Ridge District, Nevada: Insights Into Fault-Zone Architecture And Its Effect On Mineralization, K. Jill Hammond May 2001

Structural And Geochemical Analyses Of Disseminated-Gold Deposits, Bald Mountain-Alligator Ridge District, Nevada: Insights Into Fault-Zone Architecture And Its Effect On Mineralization, K. Jill Hammond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Structural and geochemical analyses of the Top and Casino deposits, Bald Mountain-Alligator Ridge district, Nevada, were conducted to determine how structures affected gold deposition in Carlin-type deposit s. We also examined how permeability changed over time in a fault that cuts siltstone-dominated sedimentary rocks. The association of gold and related arsenic with faults at the margins of a Jurassic pluton and sedimentary rocks suggests that ore fluids migrated along faults and fracture s. Permeability of the faults changed over time within the Casino deposit, where the ore-controlling fault was a distributed conduit in the early stages of mineralization but a …
