Abstract

The highly altered volcanic ash layer of Bed 79 in the Hasselbachtal Section, Rheinisches Schiefergebirge, close to the base of the Carboniferous, contains a population of magmatogenic, idiomorphic zircons with distinctive crystal morphological features. The ash was air-borne and at Hasselbachtal was far from its source. The ash layer is therefore likely to have had a wide original distribution and should be present in other rock successions of the same age deposited in a low energy hydrodynamic environment.
