FT3. Moor Gnarrenburg – Geo- and Biotope

This field trip had to be cancelled

Joachim Blankenburg, Geologischer Dienst für Bremen
September 28

The “Teufelsmoor” (Devil’s Moor) extends across the region northeast of Bremen. Its total area of 361 km2 makes it the largest marsh area in Lower Saxony, with 42% low fen and 58% raised bog. The moors are primarily used for agriculture, but there are also some peat excavation areas. In the area of the Gnarrenburg Moor, a part of the raised bog has been preserved in its near-natural state. The Huvenhoop Lake has been protected as an important geotope. In the surrounding area there is a large peat-mining district that is presently in various stages of reclamation. The 13.73 km2 protected area includes the Huvenhoop Lake and the excavation area that is being restored. The excursion will include a description of the geotope from an overlook point, a walk across the waterlogged peat-mining areas, and finally, an introduction to the moor “discovery trail”.

For the walking (4 km length) you will need sturdy shoes. The other half of the way (4 km) will be covered by train.

FT4. North Sea island Helgoland

Torsten Bickert, MARUM, University of Bremen

In a day trip it is offered to visit the rocky island of Helgoland. Situated on the NE flank of a salt dome of Zechstein evaporites, the main island together with its smaller part, the Dune, allows to study the Mesozoic to Quaternary sedimentary and structural development of the SE North Sea region. A review on historic studies combined with new aspects on the facies and mineralogy of Buntsandstein deposits will be presented on the famous western cliff of Helgoland towards the Lange Anna, complemented by a short inspection of the mineral and fossil collections of the local museum. The field trip covers in particular
  • the sedimentology, facies and lithostratigraphy of the Buntsandstein deposits
  • copper mineralisation and mining on the island
  • structural features associated with salt tectonics, embedded in the structural development of the SE North Sea
  • erosion, coastal morphology, war damages, actual problems of island protection

FT8. The Quaternary of Schleswig-Holstein – new sites (DEUQUA field trip)

Alf Grube (Geologisches Landesamt Hamburg)
September 28-30

Die Exkursion führt in eines der klassischen Gebiete der Quartärgeologie Deutschlands. Die Basis der quartären Ablagerungen in Schleswig-Holstein bilden vielerorts die Salzstöcke. Im Falle des Salzstockes Elmshorn hat die vermutlich bis heute anhaltende Aufwärtsbewegung die heutige Erdoberfläche maßgeblich geprägt. Im Bereich der Liether Kalkgrube sind durch Tektonik und Verkarstung Fallenstrukturen gebildet worden, so dass u. a. Ablagerungen des Alt-Quartärs und der prä-Elster-I Esing-Till im Aufschluss untersucht werden können. Periglaziale Bildungen werden in Form von Groß-Frostkeilpseudomorphosen vorgestellt. Im Bereich des Schalkholzer Zungenbeckens (nahe Tellingstedt) sind glazialtektonische Verstellungen sowie ein Eem-Interglazial-Aufschluss aufgeschlossen. In der Nachbarschaft zur Salzstruktur Peißen-Gnutz wird das Thema Neotektonik diskutiert, in diesem Falle in saalezeitlichen Ablagerungen.

Im Bereich der Farbeberge (Nindorf, NW´ Hohenwestedt) wurden hydrogeologische Aspekte in Zusammenhang mit Glazialtektonik sowie der Bildung von Quellmoorkuppen mit Quellkalkbildungen der Eem-Warmzeit und des Holozäns untersucht. Bei Halloh-Latendorf (E´ Großenaspe) können im Bereich eines landschaftlich schönen und gut erhaltenen Dünengebietes Bodenbildungen sowie jungholozäne Dünen-Dynamik und anthropogene Einflüsse erörtert werden. Ein Perlschnur-Esker bei Ritzerau (NW´ Nusse) gibt Anlass zur Thematisierung von Aspekten der Esker-Genese, glazifluviatiler Sedimentation und des praktischen Geotopschutzes. Der Segrahner Berg ist ein auch landschaftlich bemerkenswerter Saale-zeitlicher Stauchkomplex mit hangenden Kames-/Becken-Ablagerungen der Weichsel-Kaltzeit.

Der Rappenberg / Wiershop (NE´Geesthacht) stellt eine Jung-Saalezeitliche Stauchmoräne dar, in der glazitektonisch verstellte Tills der Elster-Kaltzeit und mehrere Tills des Saale-Komplexes aufgeschlossen sind. Der letzte Stop der Exkursion zeigt den Bereich Lütjensee / Seebergen. Hier sind in einer einmaligen landschaftlichen Kulisse Formen der Eis-Desintegration, wie Esker und Kames, zu finden, ebenso wie eine Reihe von parallelen subglazial angelegten Tälern mit glazilimnischen Ablagerungen und Strangmooren.

Die Exkursion beginnt am Donnerstag, den 28.9.2017 um 8:30 Uhr am Bahnhof Hamburg/Berliner Tor und endet dort am Sonnabend, den 03.09.2017 um spätestens 14:30 Uhr. Der Exkursionsbeitrag beinhaltet die Unkosten für den Transport in Kleinbussen sowie zwei Übernachtungen in Doppelzimmern. Er beträgt ca. EUR 160,- für DEUQUA-Mitglieder bzw. EUR 190,- für Nichtmitglieder. Optional können Einzelzimmer (plus ca. EUR 30,-: solange das begrenzte Angebot reicht) hinzugebucht werden. Studentische Mitglieder der DEUQUA erhalten eine Reduktion von EUR 60,-, finanziert durch die Nachwuchsförderung der DEUQUA. Das Platzangebot ist begrenzt und die Vergabe erfolgt in Reihenfolge des Eingangs der Anmeldungen. Bitte schicken Sie eine E-Mail mit ihren Buchungswünschen bis 30.

FT9: Enhanced Oil Recovery in the Valanginian of Bockstedt

Michael-Peter Suess, Dieter Kaufmann (Wintershall, Kassel)

September 28

Wintershall is Germany's largest internationally active crude oil and natural gas producer. We explore and produce oil and gas in Europe, North Africa, South America, Russia, and the Middle East. We have been active for over 85 years and have a workforce more than about 2,000 employees from more than 50 nationalities. As a wholly owned subsidiary of the chemical group BASF, we base our success on our technical know-how, innovation and strong international partnerships. Being active in both southern and northern Germany, the headquater of Wintershall Germany is located in Barnstorf, about 60 km south of from Bremen.

This field trip will lead us to the production sites of the Valanginian of Bockstedt near Barnstorf. The Bockstedt field is located at the boundary between the Northern Saxony Basin (to the South) and the Pompeckj Block (to the North).  The trap is generated by a fault-bound anticline (rollover at trust fault) under transpression. The target reservoir is consisting of the Valanginian Dichotomiten Schichten (KRVL.DIS) deposited as shallow marine coastal bars. Wintershall carries out experiments to enhance the oil recovery of an oil-field being under production for more than 50 years. Wintershall is investigating the application of Shizophyllan a natural, fully degradable, biopolymer derived from the fungus schizophyllum commune. The biopolymer allows to control the flow of the water in the depleted reservoir from injectors to the production wells.

After visiting the injection site we will visit the core-shed in Barnstorf to look at cores and discuss the relationship between reservoir quality, depletion and enhanced methods of oil recovery.

Snacks and drinks for lunch are provided by Wintershall Holding.

Total: 25 persons (plus 2 guides)
