AmphiWe-Augito-Trachyte and the Labrador-Au^ite-Magnetite-Tra- 

 chjto. The sedimentary rocks of the district prior to the eruptions 

 are : — U. Eocene (Tokoder sandstone), L. Oligocene (Kleinzeller clay), 

 both with marine fossils ; Oligocene freshwater- beds with lignite ; IJ. 

 Oligocene Cyrena-clay; Anomia costatu sands (Neogene). Above 

 comes over 300 feet of various Trachytic tuffs and breccias ; the oldest 

 is that of the Labrador-Biotite-Garnet-Trachyte, succeeded by the 

 Labrador- Amphibole -Trachyte. The eruption of the doleritic Labra- 

 dor-Augite-Trachyte comes at the beginning of the Sarmatian beds. 

 Enclosed in small basin-like depressions of these tuffs are Plant-beds, 

 probably Congerian. There are also Quaternary beds with trachytic 

 material, perhaps redeposited, with Ursus s^elcexLS. Tables show the 

 classification adopted and dates of eruption. E. B. T.
