  2. 1. The tectonic evolution of the western part of the Svecofennian orogen, central Sweden : Insight from U/Pb and 40Ar/39Ar geochronology at Forsmark

    Author : Tobias Hermansson; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; physical geography; Geology; Svecofennian orogen; Tectonic models; Tectonic cycles; Uplift; Cooling; Ductile deformation; Geochronology; U Pb; 40Ar 39Ar; Geologi; fysisk geografi; Petrology; mineralogy; geochemistry; Petrologi; mineralogi; geokemi;

    Abstract : The Forsmark area, in the western part of the Svecofennian orogen, central Sweden, is situated between two major Palaeoproterozoic tectonic domains that show contrasting histories with respect to timing of igneous activity, ductile deformation and metamorphism. At Forsmark, WNW to NW trending, ductile deformation belts anastomose around tectonic lenses with an inferred lower degree of ductile strain. READ MORE

  4. 2. Terrain Modelling with GIS for Tectonic Geomorphology : Numerical Methods and Applications

    Author : Gyözö Jordan; Ulf Qvarfort; Tsehaie Woldai; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; digital elevation model; digital terrain modelling; GIS; morphometry; tectonic geomorphology; Miljöteknik; Environmental engineering; Miljöteknik;

    Abstract : Analysis of digital elevation models (DEMs) by means of geomorphometry provides means of recognising fractures and characterising the morphotectonics of an area in a quantitative way. The objective of the thesis is to develop numerical methods and a consistent GIS methodology for tectonic geomorphology and apply it to test sites. READ MORE

  5. 3. Tectonic evolution of NW Svalbard

    Author : Carl Pettersson; Stockholms universitet; []
    Keywords : Svalbard; Migmatization; Zircon; Provenance;

    Abstract : The Neoproterozoic is a remarkable era in Earth’s history with dramatic variations in climate and biota, possibly resulting in global glaciations events (eg. “snowball earth”, Kirschvink, 1992) and the first appearance of metazoans (Conway Morris, 1993). READ MORE

  7. 5. Tectonic Evolution of the Zagros Suture-and Imbricate Zones in Iraq

    Author : Maher T. Zainy; Maria Ask; Francisco Gomez; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tectonic evolution; Zagros Fold-and Thrust Belt; Remote sensing; Field feological work; 3D geological modelling; Natural resources exploration; Applied Geology; Tillämpad geologi;

    Abstract : Orogenic belts are expressions of tectonic activity, often host various natural resources (e.g. petroleum and minerals reserves), and influence the society and environment through hazards (e.g. READ MORE
