1. Petrography and Thermodynamic Modelling of Svecofennian Arsenic-bearing Metasupracrustal Rocks in the Arlanda Area, West-Central Fennoscandian Shield
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The Arlanda area is a construction intensive area facing problems with risk of leaching of arsenic (As) from the bedrock to surface- and groundwater. Construction projects in the area have had problems with high levels of As in the bedrock and the risk of leaching increases through processing of aggregates and blasting of the bedrock. READ MORE

2. The “ultramafic” Intrusion’s within the peridotite from Härbergsdalen : Petrological characterization of infiltration record within the lithospheric mantle
University essay from Uppsala universitet/Mineralogi, petrologi och tektonikAbstract : The mantle constitutes ~80% of Earths volume, however, due to its location deep beneath Earth’s surface the mantle is inaccessible to study in situ. Despite this, we still have information about its composition thanks to seismic studies which haven proven the mantle to be in generally homogenous and dominated by a rock called peridotite.

3. Characterization of mineral parageneses and metamorphic textures in eclogite- to high-pressure granulite-facies marble at Allmenningen, Roan, western Norway
University essay from Lunds universitet/Geologiska institutionenAbstract : The Roan peninsula in western Norway, Vestranden, is known for exposing one of the deepest parts of the Scandinavian Caledonian orogen, similar to the Western Gneiss Region. Throughout the Roan area, eclogites and high-pressure granulite- and amphibolite-facies gneisses occur, associated with supracrustal rocks including marbles, calc-silicate rocks and amphibolites.

4. Metamorphic paragenesis and P-T conditions in garnet amphibolite from the Median Segment of the Idefjorden Terrane, Lilla Edet
University essay from Lunds universitet/Geologiska institutionenAbstract : The Sveconorwegian orogeny (c. 1 Ga) lead to the recrystallization of large parts of southwestern Sweden, with widespread metamorphism as well as local migmatization. READ MORE

5. Shock metamorphic features in zircon grains from the Mien impact structure : clues to conditions during impact
University essay from Lunds universitet/Geologiska institutionenAbstract : Jämfört med andra himlakroppar i vårt solsystem så finns det få välbevarade nedslagsstrukturer på jorden. Vi vet att jorden har påverkats av nedslag från rymden i lika stor utsträckning som övriga planeter och att dessa nedslag har influerat jordens geologiska och biologiska utveckling. READ MORE
