摘要：

A preliminary U/Pb zircon age determination has been carried out on a grey gneiss of the Eskolabreen Formation, the lowest observable lithostratigraphic unit of Precambrian metamorphic rocks in southern Ny Friesland, NE Spitsbergen. The obtained age, ca. 2,400 Ma, is considered to be a metamorphic age and suggests an Early Proterozoic tectonothermal event.
