For a long time it was thought that the 330 million year old rock in the Heimansgroeve in South Limburg is the oldest in the Netherlands, new research by TNO shows otherwise.
Geologists from the Geological Survey of the Netherlands (GDN), part of TNO, have examined microscopic fossils from a 1982 borehole near Kortgene in Zeeland and have now established that the rock is even older: 420 million years.
“This is rock that is no less than six times older than the time when the dinosaurs died out due to a meteorite impact,” says Sander Houben of GDN. “Under the microscope, I saw fossil remains of primitive primeval plants, which were the first to settle on land more than 400 million years ago.”
The discovery of the rock is geologically interesting, but also of social importance. Such old strata can be important for the extraction of geothermal energy.
