SUMMARY UNDER Central Europe is included the territory of Germany, France, Switzerland, Austria, and Czechoslovakia. The production of 1932 amounted to Germany.........229,852 Tons France .. ... ... 78,857 Czechoslovakia ... ... 18,484 Among the Central European oilfields we encounter three different types of structure 1. The oil-bearing formations in the foredeep-synclines of the alpides (" Alpides ") and in their outer chains. 2. The oil-bearing formations of the tertiary graben faults of Central Europe. 3. The oil-bearing formations within the reach of the German Zeelistein basin, which can be divided into two sections A. Primary oil deposits within the area of the weakly stressed sedimentaries of the German Zechstein. B. Secondary deposits in the north-west German basin in Mesozoic and Tertiary reservoir rocks along the structurally strongly disturbed flanks of permian salt domes. The oilfields of Gbely and Gooding in Czechoslovakia are discussed as parts of an area subsided by block faulting.within the Flysch zone of the Alps. The significance of the new discovery at the Steinberg near Zistersdorf in Austria is pointed out. In the western part of the Flysch zone there is the small oilfield of the Tegernsee. The gas and oil shows of the Austrian Schlier syncline and of the Swiss Molasso basin are discussed. This zone is continued with the asphaltic limestone of the Val de Travers in Switzerland and various asphalt deposits in Savoy. The abnormal position of the small oilfield near Gabian in southern France is pointed out. The most important oilfield in the Rhine graben is that of Pechelbronn. On the opposite side, of the Rhine valley we find the oil occurrences near Bruehsal. In the volcanic Limagne in spite of many oil-shows, no production has been obtained. The oilfields of Central and North Germany are all classified as belonging to the German Zechstein basin.Primary oil deposits are to be found in the structurally weakly stressed sedimentaries of the German Zechstein basin. To this type belongs the deposit developed since 1930 in the potash mine of Volkenroda. The possibility of discovering similar occurrences exists also in other parts of the Thuringian syncline as well as in the basin of Magdeburg-Halberstadt, near Bentheim, and on the so-called "Pompeckj" uprise. Probably the oil of the "Hauptdolomit" of the middle Zechstein is of primary origin. Secondary deposits are encountered in the north-west German basin in Mesozoic and Tertiary reservoir rocks along the structurally strongly disturbed flanks of Permian salt domes. Their trend and sequence follow the controlling structural directions of the north-west German basin. The oil-bearing structures are folded up by the young "kimmerian," "subhercynian," "laramian," and young Tertiary processes of mountain building.
