1. Paleoproterozoic deformation in the Kiruna‑Gällivare area in northern Norrbotten, Sweden : Setting, character, age, and control of iron oxide-apatite deposits
Abstract : This thesis covers the structural evolution of the Kiruna‑Gällivare area in the northern Norrbotten ore province, Sweden. The study area hosts several economically significant iron oxide-apatite (IOA) deposits and includes the type locality for this ore type. READ MORE

2. P-T evolotion and High-temperature deformation of Precambrian eclogite, Sveconorwegian orogen
Abstract : The 1.1-0.9 Ga Sveconorwegian orogen is one of several Grenvillian-aged orogenic belts that mark the amalgamation of supercontinent Rodinia. The highest-pressure rocks in the Sveconorwegian orogen are eclogites in the Eastern Segment (SW Sweden). READ MORE

3. Deformation and failure of brittle rocks under compression
Abstract : This thesis describes the deformation and failure of rocks under compression through a micromechanics model and laboratory studies of the Kaiser effect. It comprises an overview and seven appended papers. The deformation model is developed based on the analysis of the behaviour of microcracks. READ MORE

4. Deformation and failure of rock
Abstract : In this doctoral thesis work the relationship between the deformation and the initiation of failure around an underground excavation was studied. In this work data from observed failure and measured deformations was used. This work is based on information obtained from laboratory test, underground field cases and numerical analysis. READ MORE

5. Fluidized Bed Operating Parameters and Eulerian Erosion Models
Abstract : A numerical two-fluid code, Gemini 2D, was adapted to study gas-solid fluidization in arbitrary 2D domains. The code was also used to study fluid dynamic mechanisms of dense particle flow that cause ductile and brittle erosion of solids. READ MORE
