16. Physical properties of coarse particles in till coupled to bedrock composition based on new 3D image analysis method
Sammanfattning : The physical properties of the coarse fraction of the till (0.4 to 20 cm) and the surface boulders have been studied at two different sites in Sweden. LÄS MER
17. Assessing the reliability of detrital zircon in Early-Earth provenance studies
Sammanfattning : Our understanding of the Early Earth and the processes that have shaped its evolution have spawned predominantly from the geochemical and isotopic signatures of a small number of zircon populations around the world. Studies of trace element distributions, Hf and O isotope systematics as well as mineral inclusion chemistry in detrital zircon are combined with U-Pb chronology in order to constrain source rock characteristics.

18. Carved Mountains and Moving Stones : applications of Near Infrared Spectroscopy for Mineral Characterisation in Provenance Studies
Sammanfattning : The study of stone artefacts is a combination of anthropological archaeology and geology, rooted in analytical techniques for determining the materials’ composition, typological stylistic classification and interpretation of cultural patterns. In this thesis, the archaeology of materials is considered in the context of sites- and landscape transformation, economic history and development of techniques. LÄS MER
19. Geochemical trends and provenance of the Tanqua submarine fan-complex southwestern Karoo Basin, South Africa
Sammanfattning : .... LÄS MER
20. Provenance, transport, and the fate of organic matter and sediments drained through Himalayan Rivers in Nepal
Sammanfattning : Despite its small area (ca. 595,000 km2), the Himalayan region transfers disproportionally high amounts of sediments and organic matter (OM) through a network of rivers into the oceanic sink. LÄS MER
