1. Cryptic Orogeny : uplift of the Al Hajar Mountains at an alleged passive margin
Sammanfattning : Mountains evolve and grow because of the large forces that occur from the collision of tectonic plates. Plate boundaries change and move through time, and regions that were once stable, shallow-marine environments can be dragged into subduction zones and get transformed into vast mountain ranges.

2. Some problems connected with U/Th dating and temperature determination, using marine carbonates
Sammanfattning : .... LÄS MER
3. Speleothems from Warm Climates : Holocene Records from the Caribbean and Mediterranean Regions
Sammanfattning : This thesis contributes to increased knowledge on Holocene climate and environmental variability from two complex and sparsely studied areas. Using a speleothem from Gasparee Cave, Trinidad, as a paleoclimate archive, the local expression of the 8. LÄS MER
4. Climate in the eastern Mediterranean during the Holocene and beyond – A Peloponnesian perspective
Sammanfattning : This thesis contributes increased knowledge about climate variability during the late Quaternary in the eastern Mediterranean. Results from a paleoclimate review reveal that regional wetter conditions from 6000 to 5400 years BP were replaced by a less wet period from 5400 to 4600 years BP and to fully arid conditions around 4600 years BP.

5. U-Pb dating of detrital zircon from the Mt. Alfred area, Yilgarn Craton, Western Australia
Sammanfattning : Hadean and Paleo-Eoarchean aged detrital zircon provide a rare glimpse into the nature of the early Earth. Thus, the characterisation of new localities with rocks that host Hadean and Paleo-Eoarchean zircon provide invaluable insight into the Earth’s early crust. LÄS MER
