The objective of the National Research Program 20 (NRP 20), funded by the Chapter 7 covers three study areas in the Jura Mountains. In section 7. 1 a Swiss National Science Foundation, was to explore the deep structure of the reinterpretation of industry lines shed new light on the internal structure of Swiss Alps combining geophysical and geological methods.

In section 7. 1 a Swiss National Science Foundation, was to explore the deep structure of the reinterpretation of industry lines shed new light on the internal structure of Swiss Alps combining geophysical and geological methods. The data were the Folded Jura of the Neuchatel area. Here the role of thrust faults underly collected between 1986 and 1993. Processing and interpretation of the data ing major anticlines had previously been underestimated. Some of the folds involved over 50 researchers from Swiss universities and from industry. The could be interpreted as fault-propagation folds, with a detachment in the aim of this Atlas is to draw all this work together into a coherent compilation Muschelkalk evaporites. Section 7. 2 discusses the Tabular Jura around Basel. of the geological and geophysical data, their interpretation and integration A seismic line through this Basel Jura images the Moho on the southern flank into the tectonic evolution of the Swiss Alps. This turned out to be a difficult of the Black Forest-Vosges basement uplifts and suggests the presence of task. Late Paleozoic troughs underneath the Tabular Jura.
