1. 1. Syn-Magmatic Deformation Structures in the Slaufrudalur Pluton, East Iceland

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Chun Hei Ho; [2023]
   Keywords : Granite; Iceland; magma chamber; magmatic microstructure; melt fraction; mush; pluton; rheology; strain; syn-magmatic deformation;

   Abstract : 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

3. 2. Analysis of rock grouting with variable injection pressure

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Zhuohang Lian; [2022]
   Keywords : Rock engineering; Rock grouting; Variable injection pressure; Dynamic grouting technique;

   Abstract : 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

4. 3. Development of grout for deep shaft

   University essay from KTH/Byggteknik och design

   Author : Karl Lindberg; Adam von Krusenstierna; [2021]
   Keywords : Rock injection; Grout; Shaft; Laboration; Cement; Cement mixture; Bergsinjektering; Injekteringsbruk; Schakt; Laboration; Cement; Cementblandning;

   Abstract : 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

5. 4. Grouting Design Considering Different Geological Conditions : Grout evaluation for the extension of the Blue Metro Line

   University essay from KTH/Jord- och bergmekanik

   Author : Roaa Al Omari; Yasmeen Alali; [2021]
   Keywords : ;

   Abstract : 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

6. 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 institutionen

   Author : Aodhan Barrett; [2020]
   Keywords : Anorthosite; norite; Plagioclase; Hakefjorden Complex; Sweden; Trace Elements; Geochemistry; Magma Origin; Earth and Environmental Sciences;

   Abstract : 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
