G.E.O.S. analyses drill cores from the North Sea

Folded basin clay found

As part of a ground investigation, G.E.O.S. is using Vibrocorer and CPT measurements to examine around 300 kilometres of a planned cable route in the German Bight from Norderney to the "White Bank". For this purpose, the G.E.O.S. experts document and analyse each of the 170 drill cores from depths of up to 3 metres regarding structure and composition of the sediments.


As if out of a lesson book: unique basin clay folds

During the analysis of the cores, the staff came across a glacial-tectonically folded basin clay layer.

The almost "textbook-like" folded layer with basin clay underlines the glacial overprinting of sediments from the Saale period (2nd Ice Age) and can be applied to large parts of the North Sea and Baltic Sea as well as to Lower Saxony and Mecklenburg-Western Pomerania.
