  2. 6. Geophysical studies in the western part of the Siljan Ring Impact Crater

    Author : Harbe Muhamad; Christopher Juhlin; Alireza Malehmir; Daniel Sopher; Lars Nilsen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Siljan ring impact structure; Seismic reflection; Down-hole logging; Gravity; Magnetic; Tomography; Paleozoic rocks;

    Abstract : This thesis utilizes several geophysical methods to study the Siljan Ring impact structure, focusing on the western part of the structure. This thesis, and the three papers upon which it is based, reports on attempts to delineate the Paleozoic rocks at depth within the annular ring graben and characterize their structure. READ MORE

  4. 7. Regional gravity and auxiliary geophysical measurements in the Songkhla, Yala and Pattani provinces in the peninsular Thailand and their geological interpretation

    Author : Warawutti Lohawijarn; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics;

    Abstract : A regional gravity survey and VES measurements were carried out in Songkla-Yala-Pattani provinces of Peninsular Thailand, an area between latitudes 6º 15'N and 7º 15'N and longitudes 100º 15'E and 101º 30'E. In addition the aeromagnetic maps of the area have been analyzed qualitatively as well as quantitatively in this thesis, an analysis that has not been undertaken before this. READ MORE

  5. 8. High Arctic submarine glaciogenic landscapes : their formation and significance

    Author : Francis Fletcher Freire; Richard Gyllencreutz; Martin Jakobsson; Haflidi Haflidason; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High Arctic; GrIS; marine geophysics; glaciogenic landscapes; ice streams; submarine slides; Marine Geology; maringeologi;

    Abstract : This thesis is focused on studies of glacial and slope morphology in the high Arctic of western Greenland shelf and the Molloy Hole seafloor spreading area, based on high-resolution acoustic methods and other geophysical data. The main purpose is to improve our understanding of glacial dynamics and associated processes in the marginal region of a large marine-terminating ice sheet. READ MORE

  6. 9. Geological development of the East African coastal basin of Tanzania

    Author : Samson Mpanda; Ole Veibaeck; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Marine Geology; seismic methods; seismic stratigraphy; multichannel seismic recordings; tectonic development; Karoo; Mesozoic; Tertiary; East Africa; Tanzania; Earth sciences; Geovetenskap; allmän och historisk geologi; General and Historical Geology;

    Abstract : The East African coastal basin of Tanzania, which is characterised by an extensional tectonic style, is located along the passive continental margin of the western Indian Ocean. The present study is concerned with the Mafia Island and the Mafia Channel which together form a subbasin within the north-south elongated coastal sedimentary basin of Tanzania. READ MORE

  7. 10. 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
