Abstract

U-Pb data are presented for zircons from metamorphic rocks of the crystalline Odenwald that comprises part of the Mid-German Crystalline Rise. The Odenwald can be divided into four principal domains with different magmatic and metamorphic histories on the basis of published structural and petrological data and the presented ages. In the eastern (Böll-stein) Odenwald the metasedimentary rocks contain zircons derived from basement rocks that exceed 2.2 Ga in age. The intrusion of granitic magmas into these metasedimentary rocks took place before or close to the end of the thermal peak of metamorphism at 375 ± 5 Ma ago. Rapid uplift of the Böllstein Odenwald occurred at about 320 Ma bp, later than in the Bergsträsser Odenwald. The western (Bergsträsser) Odenwald can be subdivided, by geochronological, petrological and especially structural data, into a northern, a central and a southern part. In the northern part basic magmatism has an age of 362 ± 7 Ma. The peak of thermal metamorphism in the southernmost Odenwald was accompanied by partial melting of metasedimentary rocks and the formation of new zircons with ages between 332 and 342 Ma. Probable peak metamorphic conditions, revealed by two samples from the heterogeneous central part, occurred at about 336 Ma, i.e. in the same time span as in the southernmost part, but later than in the Böllstein area and the northern Odenwald. Rapid uplift started earlier in the central and southern part and 10–20 Ma earlier than in the Böllstein Odenwald. Cooling from 500 to 300°C occurred in the northern part in the time interval between the elevation of the other parts of the Bergstraesser Odenwald and the Böllstein Odenwald. There is no indication for any thermal equilibrium between 2.25 Ga and 375 Ma recorded in the zircons of both areas.
