  2. 1. Three-dimensional analysis of aeromagnetic and gravimetric data of sedimentary basins from Panama, Central America

    Author : Luis E. Santamaria Vallejos; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geophysics; Tillämpad geofysik;

    Abstract : The knowledge of the geology of the sedimentary basins from the Gulf of Panama is still quite limited. There is a lack of data from the basin geometry, the thickness, the continuity and connection between the basins, and from the characteristics of the crystalline basement rocks beneath the sedimentary basins.

  4. 2. 3D Structure and Emplacement of the Alnö Alkaline and Carbonatite Complex, Sweden : Integrated Geophysical and Physical Property Investigations

    Author : Magnus Andersson; Alireza Malehmir; Valentin R. Troll; Bjarne Almqvist; Odleiv Olesen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alnö; carbonatite; caldera; reflection seismic; anisotropy of magnetic susceptibility; gravity; magnetic; Geophysics with specialization in Solid Earth Physics; Geofysik med inriktning mot fasta jordens fysik;

    Abstract : Carbonatites are carbonate-rich magmatic rocks that are rare and of great relevance for our understanding of crustal and mantle processes. Although found on all continents and in settings ranging from Archaean to present-day, their deeper plumbing system is still poorly understood. READ MORE

  5. 3. 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

  6. 4. An attempt based on an interpretation of multichannel reflection seismic data to delineate sedimentary sequences, structures and evolution in the part of the Western Barents Sea 72° - 74°N and 10° - 17°E

    Author : Lars Ole Boldreel; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics;

    Abstract : This thesis is an attempt to throw further light on the structural development of the passive continental margin of the Western Barents Sea in the area from 72000'N to 74000'N and from 17000'E to 10000'E. It is based mainly on multichannel reflection seismics but available aeromagnetic, shipborne magnetic and free-air gravimetric data have also been analyzed. READ MORE

  7. 5. 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
