Mien is a ca. 7 km diameter impact crater occupied by lake Mien. A centrally located small island has abundant boulders of impact melt. A drillhole has been sunk from this island. Boulders of this melt and of suevite are seen in the transport direction of the last glaciation. Detailed petrophysical, gravity and magnetic measurements have been made and a model based on these data was published.
