1. Single fluid inclusion analysis using ToF-SIMS : Implications for ancient Earth biodiversiy and paleoenvironment studies
Sammanfattning : When and how life first emerged on the Earth is an area of intense research. Signs of the first life on Earth, including morphological fossils, are scarce and hard to interpret. An alternative approach is to study organic biomarkers, which are molecular fossils commonly considered as bona fide biosignatures. LÄS MER
2. Paleoenvironmental and paleoclimatic changes in northeast Thailand during the Holocene
Sammanfattning : The long-term climatic and environmental history of Southeast Asia is still fragmentary. This thesis therefore aims at studying lake sediment/peat sequences using a multi-proxy approach to reconstruct the environmental history and the impact of past changes in monsoon variability and intensity on lake ecosystems in Thailand.

3. Early–Middle Ordovician biotic and sedimentary dynamics in the Baltoscandian paleobasin
Sammanfattning : The Baltoscandian region forms part of the paleocontinent Baltica, which was largely covered by a shallow epeiric sea throughout much of the Ordovician (c. 485.5–444 Ma). This ancient sea is today recorded by a thin succession of sedimentary rocks. LÄS MER
4. Neogene lacustrine deposits in the inland basins of northern Greece : stratigraphy, paleoenvironment, paleomagnetism and industrial usefulness
Sammanfattning : Intensive tectonism in Neogene time created basins and mountain ranges in northern Greece with considerable topographic contrasts. The basins were successively filled with sediments up to a level of about +750 m. LÄS MER
