Full textMålet med denna uppsats var att analysera ifall booms i järnmalmsmarknaden har någon signifikant påverkan på lokala arbetsmarknader i utvalda kommuner i Norrbotten under tidsperioden 2000–2016. Tidigare forskning har fastställt att vissa booms och busts kan influera lokala arbetsmarknader. Analysen har genomförts med paneldata och regressionsmodeller där resultat jämförts mellan gruvkommuner och ickegruvkommuner. Resultaten gav otydliga resultat då vissa var konklusiva medan andra inte var konklusiva. Den huvudsakliga slutsatsen som nåtts är att även om gruvindustrin är en viktig del av de lokala arbetsmarknaderna, är det viktigt för företag och beslutsfattare att förstå att gruvindustrin inte är den enda påverkande faktorn och att framtida beslut och satsningar inte enbart ska baseras kring gruvindustrin och dess marknad.

Full textIn 1996, an estimated 400,000 people in a gold mining community in rural Tanzania were forcibly evicted from the area to allow for the development of a large-scale gold mine project to take place. The good-intentioned project was based on the idea of putting national development and public interest before the individual or community development and private interest. This thesis set out in 2006 to investigate how the livelihoods of the displaced community were affected by this development project. The main conclusion is that the displaced individuals had become poorer in 2006 than they were before the eviction. National development has impoverished and underdeveloped them.
The study was guided by the theory of political ecology, which I used in combination with the impoverishment risk model, focusing in particular on livelihoods. Data for this study was collected through qualitative methods as well as from secondary sources.
Using political ecology, I have been able to argue that the case study reflects a conflict over land resources, and struggles and contestations over power and meanings in society. The apparent local conflict should also be understood from the global political economy perspective.
The findings confirm the impoverishment risk model which argues that during displacement or resettlement, unless mitigative measures are taken, it is likely that the displaced people would become landless, homeless, jobless and food insecure among other negative elements. These risk elements have been found in the study area, and according to the respondents, they were a result of the displacement. On the other hand, the livelihood analysis shows how individuals and communities have been able to cope in the face of change. One of the main lessons from the study is that the project-affected people have some agency and are eager to develop themselves rather than wait for development to be brought to them by government or foreign investors. Their key concern at the moment, however, is lack of a fair compensation.

Full textFurther study using strength of evidence, regression analysis and manipulation of laboratory formulated media, indicated that the mine effluent was the primary causal agent of the observed biotic impairment, and its toxicity could be attributed to sodium/sulfate-dominated TDS, which is significantly ameliorated by water hardness. Finally, although testing with lentic cladocerans, such as Ceriodaphnia, is consistent, cost-effective and sensitive to TDS related toxicity, the ecological relevance and protective capability of such testing is questionable when assessing contaminant effects on sensitive macroinvertebrates indigenous to lotic systems. A more ecologically relevant laboratory bioassay using the mayfly, Isonychia bicolor, in simulated lotic microcosms provided more sensitive endpoints than Ceriodaphnia and Pimephales promelas. Although the heartiness of Isonychia in laboratory conditions is poorly understood relative to standardized test organisms, these results, along with potential toxic impacts from numerous sodium/sulfate-dominated wastewaters discharging into freshwater systems, may have important implications to future national pollution discharge and elimination system (NPDES) permit testing. Currently, however, strong recommendations can only be made using Ceriodaphnia endpoints. Potential acute toxicity to aquatic organisms in high hardness solution (~790 mg/L as CaCO3) is possible where sodium/sulfate-dominated TDS levels exceed ~7000 uS/cm (5167 mg/L), with potential chronic toxicity occurring at ~3200 uS/cm (2342 mg/L). These endpoints were significantly reduced in solutions of lower hardness (88 mg/L as CaCO3), with acute and chronic toxicity occurring at 5100 uS/cm (3754 mg/L) and ~2100 uS/cm (1523 mg/L), respectively. Point source discharges causing instream TDS concentrations to exceed these levels risk impairment to aquatic life.

Full textReduced intrusion-related gold (RIRG) deposits have been documented around the globe, and have been best studied in Alaska and Yukon, but few examples have been documented in Nevada. One occurrence in Nevada is the Jurassic Bald Mountain deposit in eastern Nevada; however, for most Nevada occurrences there has been insufficient work that establishes a genetic connection to intrusions or determines their age.
Buffalo Canyon is a gold prospect located near the historic Berlin mining area in northern Nye County, Nevada, where gold, silver, copper, lead and zinc were mined in the past from mesothermal quartz veins. Buffalo Canyon contains the more recently discovered Everson prospect, a poorly defined gold deposit, which has characteristics of RIRG deposits. The district includes a series of intrusions emplaced into Triassic metasedimentary and metavolcanic rocks. These previously undated intrusions vary in composition from diorite to granodiorite and granite. U-Pb dating of zircons by LA-ICPMS has revealed distinct intrusive events in the Jurassic, Cretaceous, and Oligocene. Metaluminous, biotite-pyroxene diorite stocks to porphyritic granodiorite dikes have been dated at 162.03 + 0.91 Ma and 158.72 + 0.94 Ma, respectively. Peraluminous, ilmenite-bearing leucogranite plugs and dikes have been dated at 81.96 + 0.43 Ma and 82.9 + 0.30 Ma, respectively. A variety of Oligocene dikes and small plugs that include quartz-monzodiorite, quartz monzonite, dacite and granite are metaluminous to peraluminous and locally ilmenite-bearing. Four dates of Oligocene intrusions fall within error of each other. They yielded dates of 25.13 + 0.29, 24.9 + 0.30, 24.8 + 0.40 Ma and 24.6 + 0.30 Ma.
Country rocks at Buffalo Canyon, particularly those near Jurassic intrusions, are metamorphosed to biotite hornfels. Biotite hornfels is overprinted by sodic-calcic alteration that is likely related to Jurassic intrusive activity, and consists primarily of actinolite + albite in veins and disseminated patchworks. Mesothermal quartz veins have a Au-Ag-(Sb-Pb-As-Cu) geochemical signature, are composed predominantly of moderately deformed, recrystallized quartz and contain liquid CO2-bearing fluid inclusions. Mesothermal quartz veins are hosted within Jurassic intrusions and are post-Luning-Fencemaker thrust (mid-Jurassic) deformation. Small volumes of Oligocene intrusive rocks are variably altered to muscovite-tourmaline or propylitic assemblages. Base-metal sulfide mineralization occurs as veins and replacements, both of which are associated with tourmaline as a dominant gangue mineral. Base-metal sulfide mineralization has a Ag-Pb-Zn-Sb-As-(Au-Bi-Cu-Mo) signature.
Free gold within low sulfide, 1-10cm thick, sheeted, crack-seal quartz veins with locally developed sericite-tourmaline envelopes define the bulk of the Everson gold mineralization. Other gangue minerals in these veins include muscovite, tourmaline and fluorite. The veins have a Au-Te-(Mo-Bi-Sn) signature and high Au:Ag ratios (>1:1). The quartz in these gold-bearing veins contain common hypersaline brine and coexisting vapor-rich fluid inclusions, indicative of trapping within the two-phase brine + vapor field. Combined with estimated thicknesses of older and coeval Oligocene volcanic rocks, the fluid inclusions suggest the deposit formed at <~3 km paleodepth. The Everson-related quartz veins also cross-cut mapped Jurassic intrusive rocks, sodic-calcic veins, base-metal sulfide mineralization, and Oligocene granitic intrusions. Muscovite and tourmaline + fluorite associated with alteration and mineralization suggest a greisen-like style of alteration and mineralization. The preponderance of evidence suggests that most gold mineralization at Buffalo Canyon is Oligocene in age, related to a felsic intrusion that only crops outs locally, but is likely extensive in the subsurface. Buffalo Canyon bears strong similarities to typical RIRG systems, and there are likely additional unknown examples within Nevada. A significant outcome of this study is that Buffalo Canyon formed in the Oligocene, related to volcanism during slab rollback that led to the ignimbrite flare-up in the central Nevada. Though most RIRG systems in Nevada could indeed be Mesozoic, the research on Buffalo Canyon opens the possibility that similar deposits may also be related to much younger intrusions that may be largely covered by coeval Tertiary volcanic rocks.
