Devonian sediments of East Greenland VI. Review of results

Résumé

Seventy generalised stratigraphical columns, and alphabetical and hierarchical indexes of the lithostratigraphical units, are used to summarise stratigraphical relationships. The total aggregate thickness is 10 400 m, adding the maximum thicknesses of each of the five major units. Vertebrate fossils indicate an age range from Upper Middle Devonian (Givetian) to highest Devonian or lowest Carboniferous (Famennian or Tournaisian). A palynological survey has yielded two good micro-floral assemblages, one of Middle to Upper Givetian age, and the other of late Frasnian or early Famennian age, and both of these are consistent with the vertebrate evidence. Conglomerate, sandstone, siltstone and volcanic rock lithological associations are reviewed, and provide detailed evidence of local processes and environments. Some of the most original information concerns the three-dimensional patterns of major sedimentary rock bodies, representing different environmental situations.
