1. Syn-Magmatic Deformation Structures in the Slaufrudalur Pluton, East Iceland
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Structures and deformation mechanisms of magmatic rocks are controlled by rheology. An increase in melt fraction can weaken a rock body and localises significant amount of strain. This interplay between rheology, melting and deformation in a magma reservoir, however, is not always clearly documented in literature. LÄS MER
2. Lejarfjället Garnet(?) Peridotite – Origin and Petrological Characterization of Symplectitic Aggregates in Ultramafic Rocks
Kandidat-uppsats, Uppsala universitet/Mineralogi, petrologi och tektonikSammanfattning : Ultramafic rocks are abundant in the Earth’s mantle but rare on the surface. Since no in-situ samples from the mantle can be collected, mantle rocks provide knowledge of mechanisms operating in the mantle and large-scale processes that brought them up to the surface. LÄS MER
3. Structural investigation of ductile deformations across the Frontal Wedge south of Lake Vättern, southern Sweden
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Deformationszonen kallad ”Frontal wedge” är ett system av N-S branta och vertikala deformationszoner i gränsen mellan Svekonorvegiska och Sekorareliska provincen, i södra Sverige. Ursprung av dessa strukturer är inte fullt förstått och under de senaste årtiondena har endast ett fåtal undersökningar gjorts på dessa deformationszoner. LÄS MER
4. Three-dimensional modelling of the Källfallsgruvan iron oxide deposit, Riddarhyttan ore field, Bergslagen, Sweden: Integrating existing and new data to aid understanding of structural controls and mineral exploration
Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : The Bergslagen ore province, located in the Fennoscandian shield in the south-central part of Sweden hosts several metallic mineral deposits, one of them being the Källfallsgruvan iron-oxide deposit in the Riddarhyttan ore field, situated in a high-strain shear belt denoted as the West Bergslagen Boundary Zone (WBBZ). An accurate 3D geological model of the Källfallsgruvan iron-oxide deposit has been generated to aid understanding of the ore body geometries and calculating volume and tonnage. LÄS MER
5. Akustisk emission vid skärande bearbetning från den adhesiva mekanismen som funktion av förslitningsutvecklingen
M1-uppsats, Högskolan i Gävle/Avdelningen för industriell ekonomi, industridesign och maskinteknikSammanfattning : The adhesive mechanism is one of the most significant degradation processes of the edge in metal cutting. Although knowledge about adhesion and edge buildup (BUE) has increased in recent years, there are still areas that are less explored. LÄS MER
