A cross-section of the Inn-valley has been surveyed by refraction- and refiection-seismic and gravimetrie methods. The thickness of the Inn-va.!ley sediments is 340- 390 m. At the northern edge of the valley an intermediate layer between sediments and basement has been detected, which is up to 300 ITl thick. This zone seems to mark the boundary of the northern calcareous alps.
