Global Interpretation of Crustal Reflection Data for CrustalStructure and Genesis

点击翻译按钮获取中文摘要

Research will concentrate on the synthesis of data from continent-continent collision zones, specifically the Swiss Alps and the Norwegian Caledonides. This will be based on the opportunity to compare these orogenic belts at different levels of exposure. This work will be carried out by the PIs, two graduate students, and two people each from the University of Bergen, ETH-Zurich, and one from the University of Bern. Interpretation will include both vertical-incidence and wide- angle reflection data and will start with analysis of recording and processing effects on the data. Final interpretation will be based on a combination of migration and 2-D and 3-D modeling. Wide-angle data will be inverted for 1-D and 2-D velocity structure, and this will be a major aspect of the interpretation.
