Abstract (sommario):

The northern Norrbotten ore province is an intensely mineralised area and has traditionally been a very important mining district. It contains Fe, Cu-Au, Au, and Ag deposits ranging from world-class ore deposits to small and uneconomic ones (Martinsson 2004). The most important are the Kiruna and Malmberget iron ores and the Aitik Cu-Au deposit.The cross-discipline approach called geometallurgy connects two different but closely related areas in the mining industry, namely geology and mineral processing. It involves understanding and measurements of the ore properties significant for its succe

Abstract (sommario):

The Tjårrojåkka area is located about 50 km WSW of Kiruna, northern Sweden, and hosts one of the best examples of spatially related Fe-oxide Cu-Au occurrences (the Tjårrojåkka-Fe and Tjårrojåkka-Cu). The bedrock, depositional environment and tectonic evolution of the area were studied through petrological, geochemical and geophysical-petrophysical investigations. The bedrock is dominated by intermediate and basic extrusive and intrusive rocks. The intermediate andesites and basaltic andesites are cut by diabases which acted as feeder dykes for the overlying basalts. The intrusive rocks range f

Abstract (sommario):

The Falun pyritic Zn-Pb-Cu-(Au-Ag) sulphide deposit, situated in the Palaeoproterozoic (1.9–1.8 Ga) Bergslagen lithotectonic unit in the south-western part of the Fennoscandian Shield, is one of the major base and minor precious metal sulphide deposits in Sweden. Host rocks to the deposit as well as the ores and altered rocks were metamorphosed and affected by heterogeneous ductile strain during the Svecokarelian orogeny the total duration of which was 2.0–1.8 Ga. These processes both reworked the mineral assemblages of the original hydrothermal alteration system and reshaped the structural ge

The Palaeoproterozoic Skellefte mining district in northern Sweden covers an area of 120 by 30 km and is one of the most important mining districts in Europe, producing mainly Zn, Cu, Pb, As and Au from volcanogenic massive sulfide (VMS) and orogenic gold deposits.Detailed mapping of structures and stratigraphy within the sedimentary Vargfors Group combined with a structural analysis revealed a syn-extensional fault pattern of NW-SE-trending normal faults and associated NE-SW-trending transfer faults, creating the segmented sedimentary Vargfors basin.

Abstract (sommario):

The well-known Skellefte Ore District, northern Sweden, hosts a large number of massive sulphide deposits, a few porphyry-type-deposits and a number of gold deposits in different geological settings. Southwest of this district a new ore province, the so called Gold Line, is presently being uncovered. During the past decade a number of gold occurrences have been discovered in this area. Only one deposit is in production, the Svartliden gold deposit (2 Mton at 4.3 ppm Au). However, with regards to tonnage the Fäboliden gold deposit stands out with a known mineral resource of c. 16 Mton with 1.33

Dating relates the high-pressure metamorphism to the Late Ordovican subduction of the Baltoscandian margin during the closure of the Iapetus Ocean.

Abstract (sommario):

Rockliden is a polymetallic Zn-Cu volcanic-hosted massive sulphide (VHMS) deposit. It is located in north-central Sweden about 150 km south of the Skellefte ore district. Two major challenges to mining and production were identified soon after Rockliden was discovered in the 1980’s. Firstly, the geographic distance to Boliden’s main ore deposits and existing concentrator in the Skellefte district will set additional financial and logistic constrains for the processing of the ore. Secondly, the locally high Sb grade in the ore potentially lowers the quality of the Cu-Pb concentrate sent to the

In an early stage the lake was dammed between the two ice lobes but as they retreated the glacial lake was enlarged in the eastern part where it in the later stage was dammed by topography.

Scouring ice keels present logistical problems to the safe installation and operation of, for example, oil and gas production pipelines and power and telecommunication cables in several cold ocean regions.

Abstract (sommario):

People cannot be trained to marvel at landscapes, nor to love their places and their planet. On the other hand, love of place and of the Earth are scarcely sentimental extras to be indulged only when all technical and material problems have been resolved... The experiences of places, spaces and landscapes in which academic geography originates are a fundamental part of everyone's experience, and geography has no exclusive claim to them. Indeed, one of the first aims of a phenomenology of geography should be to retrieve these experiences from the academic netherworld and to return them to ever

Abstract (sommario):

Seven bedrock landslides situated within quartzofeldspathic schist exist up slope of the residential area along the Frankton Arm of Lake Wakatipu, South Island, New Zealand. Engineering geological and geotechnical failure models for these landslides have been established using engineering geological mapping at scales of 1:5000 and 1:10000, geotechnical testing, and the development of limit-equilibriurn sensitivity models. Geotechnical testing of artificially fractured schist bedrock obtained shear strength values of Φ = 24°-36° and zero cohesion, and point load strength indexes of 0.6-3.83MPa

Abstract (sommario):

The research embodied in this thesis arose from a contract to remap Sheet 87W of the 1:50,000 geological map for the Geological Survey. The rocks investigated include late Precambrian to early Cambrian metasediments of the Dalradian Supergroup, and Caledonian intrusive igneous rocks. The range of sedimentary facies present within the Methlick Formation (Southern Highland Group) is described within the framework of current deep marine clastic facies classifications, and an inner to middle submarine fan facies model erected. Framework petrography, palaeocurrents, geochemistry and facies variatio

Abstract (sommario):

The granitic rocks are subdivided into four series: tholeiitic, alkaline, calc-alkaline and mobilizates. These series can be formed from melting of mantle material (M-type granites) or from crustal rocks. There are granitic rocks formed from the mixing of these two magmas types. The rocks formed from crustal anatexis are subdivided into those formed from igneous rocks (I-type granites) and those formed from meta-sedimentary rocks (S-type granites). The former has similar characteristics to the mantle-derived granitoids. The mineral deposits related to igneous or mantle derived magma usually ar

Abstract (sommario):

Since different parts of the Moon display varying magnetic field strengths, our goal was to determine whether these differences are due to specific geological characteristics. We found that older materials tend to be more magnetic than younger materials. Additional statistical studies found that the mare regions of the Moon are less magnetic than the plains and terra regions. We did not find a simple relationship between lunar magnetism and crustal thickness, and this is inconsistent with the hypothesis that thicker crust is more magnetic since there is additional material. Thus, it is not jus

Abstract (sommario):

Porcelain is a translucent vitreous material that consists of clay (kaolin), feldspar and quartz which has been mixed and heated together to cause a metamorphic reaction. In Sweden, the Porcelain industry was established in 1726 at Rörstrands castle in Stockholm and is today one of the oldest industries in Europe to produce porcelain. Around the 1790’s Rörstrand got its feldspars and quartz from the Ytterby mine that was located at Resarö in Stockholm’s archipelago making the raw material somewhat easy to access. Rörstrand owned the mine in the 1850’s to 1926. During the time Ytterby mine was
