In the southern Pyrenees foreland, the Cardona salt diapir has a 250 m high stem and a small bulb, which is partially exposed. The internal structure of the diapir consists of a main sheath fold divided by a shear zone. This shear zone crosses two salt units with different initial properties. In this paper, a qualitative analysis of the fabric both units crossed by the shear zone and a 3D quantitative morphological and textural analysis of the unit with small grain size were carried out. In this unit, the fabric is characterized by a grain size similar to that...

The ten articles in this book describe the mode of emplacement of various types of intrusions (salt diapirs, mud volcanoes and magmatic bodies) by means of theoretical reasoning, analogue and analytical modelling, interpretation of seismic and field data, and geodetic surveying. All the articles emphasize the role of regional tectonics in driving or controlling the emplacement of the intrusions. The selection of articles includes examples from Spain, Romania, onshore and offshore Italy, the Eastern Mediterranean, Israel and iran.
Better understanding of the mode of emplacement of these intrusions has applications in hydrocarbon exploration (e.g., where salt structures or mud diapirs are present) and in the mining industry (where mineralization is related to the emplacement of batholiths).
