  2. 11. Deep seismic studies in the western part of the Baltic shield

    Author : Johannes Schmidt; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Abstract : The Caledonides form an ancient orogenic belt at the western margin of the Balticshield and in Scotland. They are the result of a three-part continent collision thattook place c. 430-390 million years ago. READ MORE

  4. 12. Crustal stress studies using microearthquakes and boreholes

    Author : Björn Lund; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : The state of stress in the crust is essential for the understanding of geodynamic processes such as the transmission of plate driving forces through the lithosphere and the triggering of earthquakes. This thesis describes the development and application of new methods for the estimation of crustal stresses. READ MORE

  5. 13. Studies of Volcanic Plumes with Remote Spectroscopic Sensing Techniques -DOAS and FTIR measurements on volcanoes of the Network for Observation of Volcanic and Atmospheric Change-

    Author : Santiago Arellano; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; FTIR; Remote Sensing; DOAS; NOVAC; Volcanic gas emissions;

    Abstract : Volcanism is a rich geodynamical process, closely linked to the origin and ongoing evolution of the lithosphere, atmosphere, hydrosphere and biosphere. Humans have benefited from the resources provided by volcanoes but also been threatened by the dangers of volcanic eruptions, which accurate prediction remains elusive. READ MORE

  6. 14. Evolution of the earliest molluscs

    Author : Alexander P. Gubanov; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Historical Geology and Paleontology; historisk geologi och paleontologi;

    Abstract : The first helcionelloid molluscs appeared in the late Vendian and were forerunners ofthe sudden molluscan diversification of the Cambrian explosion. The diversification ofMollusca coincided with global changes in the lithosphere, hydrosphere, atmosphere,and biosphere coincident with the break-up of the Late Proterozoic supercontinentRodinia, a distinct shift in oceanic water geochemistry, and the sudden abundance ofshelled multicellular organisms.

  7. 15. Thin sheet approximations for geodynamic applications

    Author : Sergei Medvedev; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; mineralogi; petrologi och tektonik; Mineral Chemistry; Petrology and Tectonics;

    Abstract : Thin sheet approximations are widely used in geodynamics because of their potential for fast computing of 3D lithospheric deformations using simple numerical techniques. However, this simplicity imposes limits to boundary conditions, rheological settings and accuracy of results. READ MORE
