1. Syn-Magmatic Deformation Structures in the Slaufrudalur Pluton, East Iceland
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : 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. READ MORE

2. Analysis of rock grouting with variable injection pressure
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : Rock grouting is an effective technique frequently used in rock engineering to reduce groundwater ingress and increase the stability of surrounding rock mass. The real time grouting control (RTGC) is one of widely used analytical models to predict the grouting process. READ MORE

3. Development of grout for deep shaft
University essay from KTH/Byggteknik och designAbstract : In tunnel engineering one of the most important factors are the groundwater flow. To solve this problem a method called grouting is commonly used. In this study grout mixes are developed based on specific requirements for a deep shaft located next to a body of water. READ MORE

4. Grouting Design Considering Different Geological Conditions : Grout evaluation for the extension of the Blue Metro Line
University essay from KTH/Jord- och bergmekanikAbstract : This thesis forms the basis for a new documented experience of grouting design and work in the extension of the blue metro line in Stockholm. It includes documentation of the grouting design based on theoretical basis, stop criteria and fan geometries for favorable and unfavorable geological conditions. READ MORE

5. Major and trace element geochemical analysis of norites in the Hakefjorden Complex to constrain magma source and magma plumbing systems
University essay from Lunds universitet/Geologiska institutionenAbstract : Major and trace element data taken from plagioclase crystals from anorthosites and related rock units in the Hakefjorden Complex located off the west coast of Sweden were investigated for the purposes of constraining magma chamber processes and the source of the magma. Although the anorthosite units were completely homogenous in regards to its chemistry, the plagioclase in the associated norite and ilmenite-leuconorite units showed substantial variation. READ MORE
