Odenwald field trip

Field guide: Martin Okrusch

Departure/Arrival: 8.30h conference venue in Frankfurt / approx. 19.00h at Frankfurt central railway station (Hauptbahnhof)

Costs: 65 €

Min. participants: 8

Max. participants: 29

Costs include snacks and drinks in the bus as well as the field guide booklet Beih. z. Eur. J. Mineral. Vol. 12, No. 2 (2000) with the article by Okrusch, M., Schubert, W. & Stähle, V.: The Odenwald, Germany, Variscan metamorphic evolution and igneous events, 45-89


The one-day field trip to the Odenwald gives an overview of the inventory of the deeper parts of the top plate of the Variscan orogeny in middle Europe. We will study the mafic and intermediate members of the plutonic suite, amphibolites and high grade metamorphic (kinzigite) to anatectic metapelites. The Odenwald was uplifted in the Tertiary by the Rhinegraben rifting. As a consequence, SiO2-undersaturated volcanic rocks were emplaced. We will see an olivine nephelinite plug with small mantle fragments and green glasses of molten crustal xenoliths. We will also visit an old Roman quarry in a diorite with cleaved and wire sawed blocks and an almost finished Roman column.
