Rotation of porphyroblasts
in a shear zone. Bons Amphibolite-facies rocks at Cap de Creus (NE Spain) contain abundant andalusite porphyroblasts, that are rotated together with the surrounding foliation. This project involves a systematic analysis of the relationship between the orientation of internal and external foliation, and the strain that the rocks experienced |

Rheological contrasts in metamorphic
turbidites Bons Cleavage refraction, fold shape and fold wavelength-amplitude relationships give insight in the rheological contrasts between metapelitic and metapsammitic layers in folded turbidites at Cap de Creus, NE Spain |

Strain analysis on
tourmaline rims on veins Bons Tourmaline impregnated the wall rock of (pegmatite) veins at cap de Creus, NE Spain. These tourmaline rims provide a unique opportunity to determine the deformation that post-dated vein formation |

The formation of Manchuriophycus-like shrinkage cracks in sediments Bons & Koehn (Uni. Mainz) Proterozoic sandstones sometimes have sinus-shaped shrinkage cracks, originally wrongly interpreted as trace fossils (Manchuriophycus). Samples from Australia are available for analysis and such structures can be modelled with Elle. |

Axial planes parallel to
veins and dykes Bons & Becker Magmatic veins (in migmatites) are often oriented parallel to axial planes of folds. Most people assume the dykes intruded parallel to the axial planes. This numerical project investigates the new hypothesis that axial planes orient themselves parallel to veins. |

Gypsum veins in the Gypsum
Keuper near Tübingen Bons The Keuper of Baden-Württemberg has many fibrous gypsum veins. A small project would entail the description of these veins in outcrops near Tübingen (Wurmlingen). A full Diplom-project would involve more detailed thin section and SEM analyses |

Structures in the Molinos
mapping area (multiple projects possible) Bons The student mapping area at Molinos (Spain) has some poorly-understood thrust and fold structure in the Mesozoic strata. One or more projects can be done to analyse some of these complex structures in detail. |

Fossil fauna in the Lower
and Upper Jurassic Strata at Molinos (multiple
projects possible) Nebelsick & Bons Two levels in the Jurassic at Molinos are particularly rich in fossils: Brachiopods, Gastropods, Belemnites, Sponges, Bivalves, Echinoids, etc.. The project(s) would entail making a detailed inventory of these fossils. |

Calcite veins at Molinos Bons Many and big calcite veins are found in some strata in the student mapping area at Molinos. Their relationship with the fold and thrusts is unclear. A full Diplom-project would also involve 3-D analyses of the crystal structure, as well as SEM work. |
