dc.description.abstract | The Møklevatnet granodiorite in the Gjersvik Nappe has yielded a U-Pb zircon age of 456 +- 2MA from three, concordant, mulitigrain fractions. This can also be regarded as a maximum age, Early Middle Caradoc, for the oldest sediments in the unconformably overlying Limingen Group. Taken in conjunction with isotopic data reported earlier, the zircon age for the Møklevatnet pluton indicates that the magmatic activity represented in the Gjersvik Nappe extended over a period of 25 to 30 million years. | |
