6. Samband mellan geologiska och bergmekaniska egenskaper i bergmaterial som bärlager till riksväg 51 : Riksväg 51 sträckan Svennevad - Kvarntorpskorset
Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : This thesis was created to ensure the quality of the rock which would be crushed to base layer construction material, in a road cut at Swedish highway 51, and to find a possible link between the rock's abrasion resistance and its mineralogy. Rock samples were collected, and among other things, several ball mill tests were carried out. LÄS MER
7. A geophysical study of the Mertainen area : Modelling and interpretation of primarily aeromagnetic data
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geovetenskap och miljöteknikSammanfattning : Nautanen Deformation Zone, is a prominent deformation zone in the Malmfälten area, which is of importance to understand for mineral exploration purposes. In spite of diverse geophysical data being available in Malmfälten and the good correlation between airborne measurements and geological observations, the area has not been fully investigated in detail using the aforementioned available data.

8. Shock metamorphic features in zircon grains from the Mien impact structure : clues to conditions during impact
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : 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. LÄS MER
9. The influence of weakness zones on the tunnel stability based on investigations in Bodøtunnelen
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/GeoteknologiSammanfattning : When planning for a tunnel, the ground conditions in which the tunnel is going to be excavated through will be investigated to different extent. Lack of relevant pre-investigation data or misinterpretations of the available data can cause both economical and/or unexpected stability problems. LÄS MER
10. Alteration of the Bjursås Ore Field, Oxberg, Bergslagen District, Sweden
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The Bjursås ore field is located within the Bergslagen domain of central Sweden just northwest of the town of Falun. The field hosts small scale mines such as the 17th century Floberg copper mine and has been the focus of mineral exploration on several occasions during the 20th and early 21th century, with no major economic deposits being uncovered as of yet.
