  1. 1. Marine Geology and Holocene Paleoceanographyof the Southern Quark, Baltic Sea

    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

    Author : Anton Wagner; [2022]
    Keywords : Bottom currents; Sortable silt; Radiocarbon dating; Baltic Sea stages; Estuarine circulation; Marine sediment cores; Marine geophysical mapping;

    Abstract : The Understen-Märket trench is located in the Southern Quark and is the only deep-water connection between the Baltic Propper and the Gulf of Bothnia. Bathymetric mapping reveals a number of eroded channels and drift deposits exists on the seafloor, indicating that the area is heavily affected by current activity. READ MORE

  2. 2. Monitoring of heat exchanges in thesnowpack of Foxfonna glacier, Spitzbergen,Svalbard.

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Author : Thibault Desjonquères; [2022]
    Keywords : Glaciers; Glaciology; Svalbard; Geophysics; Superimposed Ice; Foxfonna; Geology.; Physics and Astronomy;

    Abstract : The processes of meltwater storage in firn and the impact of refreezing on firn-coveredglaciers have been investigated on the Greenland ice-sheet. On Svalbard, climate changepromotes the disappearance of firn on glaciers. READ MORE

  3. 3. Identification and strength classification of weakness zones in the Garpenberg mine based on measurement while drilling (MWD)

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Ioannis Peroulakis; [2022]
    Keywords : Drilling; MWD; Garpenberg; Mining; Geotechnics;

    Abstract : Boliden’s Garpenberg mine produces Zn-Pb-Ag(Cu-Au) using a sublevel stoping with pastefill mining method. The orebody is strongly affected by the existence of weakness zones mainly consisting of Talc Schist and Phlogopite Schist which affect the design, planning and production of the stope. READ MORE

  4. 4. A re-investigation of hummocky moraine formed from ice sheet decay using geomorphological and sedimentological evidence in the Vomb area, southern Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Tim Bjermo; [2022]
    Keywords : glacial geomorphology; remote sensing; LiDAR; sedimentology; glacitectonite; deformation structures; hummocky moraine; quaternary geology; deglaciation; glacial geomorfologi; fjärranalys; sedimentologi; glacitektonit; deformationstrukturer; småkullig morän; backlandskap; moränlandskap; kvartärgeologi; Earth and Environmental Sciences;

    Abstract : Glacial sediment-landform assemblages have long been used to reconstruct the dynamics of ice sheets throughout the Quaternary time period, particularly so for the period of the last glaciation in northern Europe and southern Scandinavia. One such sediment-landform assemblage is hummocky moraine, which has previously been used as an all-encompassing descriptive terminology strongly associated with dead ice meltout and passive deglaciation.

  5. 5. Structural investigation of ductile deformations across the Frontal Wedge south of Lake Vättern, southern Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Ellinor Halvarsson; [2022]
    Keywords : Frontal wedge; deformation zone; Sveconorwegian orogeny; Sveconorwegian Orogen; Eastern Segment; shear-sense indicators; Protogine zone; structural geology; bedrock geology; Earth and Environmental Sciences;

    Abstract : Deformationszonen kallad ”Frontal wedge” är ett system av N-S branta och vertikala deformationszoner i gränsen mellan Svekonorvegiska och Sekorareliska provincen, i södra Sverige. Ursprung av dessa strukturer är inte fullt förstått och under de senaste årtiondena har endast ett fåtal undersökningar gjorts på dessa deformationszoner. READ MORE
