| Abstract: | - Multispectral scanning imageries, revealed from ERTS-1 satellite, show a young lineament pattern in the region of the Northern Calcareous Alps. The statistical distribution of the lineament directions accords well with that of mapped faults. On the other hand, many of these lineaments are not mapped as faults. A more complex type of fracture is supposed for them, composed of many joints and minor faults. With increasing length of the fracture, the acute angle of the shear system increases from about 40° at joints to 70° at faults and 80° at lineaments.
- The satellite imagery shows a relationship between the structures of the folded molasse and the alpine nappes. The mimer and depth of folds, the width of the folded zone, and the lateral limitation of the synclines are related to the amount of thrusting of parts of the nappe system. A model for the genesis of the folded molasse is given.
