Advanced synchrotron texture analysis of phyllosilicate-rich rocks from different tectonic settings – Understanding texture-forming processes and anisotropic physical properties
(2019-11-18)Texture analysis, i.e. the analysis of the crystallographic preferred orientations of minerals in rocks, contributes to the understanding of the deformation history and physical properties of rocks. Methods generally applied ... -
Management Options for Optimizing Nutrient Cycling and Reducing Greenhouse Gas Emissions from Smallholder Rice Farms in Vietnam
(2019-11-15)Summary Rice is the most important food crop in Asia. However, rice production in Asia is facing tremendous challenges in the 21st century. Fast-growing populations are demanding larger rice supplies under the increasingly ... -
Late Palaeozoic to Early Mesozoic evolution of the Palaeotethys in Turkey: Insights from the Karaburun Peninsula and the Konya Complex
(2019-11-08)The greater aim of this PhD thesis is to test the current palaeotectonic models for the Late Palaeozoic to Early Mesozoic evolution of the Palaeotethys in the Eastern Mediterranean. Therefore, siliciclastic rocks from two ... -
Biosignatures of modern microbial mats, Kiritimati/Kiribati, Central Pacific
(2019-10-17)Organic biomarkers have been widely used to trace the information of their biological precursors and to reveal information about fossil depositional environment, and thus they help to reconstruct ancient ecosystems. Prior ... -
