  4. 22. On modelling of postglacial gravity change

    Author : Per-Anders Olsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; accurate predictions of the gravity change are important for e.g. reductions of geodetic observations to a reference epoch. During the last decade; Glacial isostatic adjustment GIA is the Earth s response to glacial-induced load variations on its surface. This phenomenon can today be observed in; contribute different and complemental information on the phenomenon. Knowledge of the gravitational component is important for understanding the underlying geodynamical processes. Further; such as vertical and horizontal deformation of the crust; efforts to observe the surface gravity change in Fennoscandia have been intensified and the observational accuracy successively improved. This offers new possibilities at the same time as it puts new demands on modelling. The purpose of this thesis is to study some aspects of the modelling of GIA-induced gravity change; North America and Fennoscandia. Different observables; relative sea level change and disturbances in the gravity field; for example;

    Abstract : Glacial isostatic adjustment (GIA) is the Earth's response to glacial-induced load variations on its surface. This phenomenon can today be observed in, for example, North America and Fennoscandia. READ MORE

  5. 23. The forgotten forest : on thinning, retention, and biodiversity in the boreal forest

    Author : Julian Klein; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Fennoscandia has had a long history of intensive forest management. It can therefore be regarded a trial zone for other boreal regions which are still largely unaffected by forestry. In Fennoscandia, forestry has resulted in many threatened species and methods that maintain biodiversity have therefore been called for. READ MORE

  6. 24. Deformation and failure of hard rock under laboratory and field conditions

    Author : Kelvis Pérez; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Abstract : The understanding of the fracture mechanisms and failure processes of the rock is an important requirement for the design of mining excavations and civil engineering constructions. The fracture process is necessary for the excavation and fragmentation of rock, but fracture of rock must be avoided and controlled to preserve the integrity of the construction. READ MORE

  7. 25. The Mesoproterozoic Hallandian event - a region-scale orogenic event in the Fennoscandian Shield

    Author : Linus Brander; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fennoscandian Shield; Hallandian orogeny; Eastern Segment; Protogine Zone; U-Pb geochronology; zircon; baddeleyite; Nd-isotopes; Hf-isotopes; tectonic model;

    Abstract : The Sveconorwegian Province occupies the southwestern part of the Fennoscandian Shield. The easternmost tectonic unit of the Province is the 1710-1660 Ma parautochthonous Eastern Segment, which bears the imprint of at least two metamorphic events; the 1460-1380 Ma Hallandian and the 1150-970 Ma Sveconorwegian.
