Oxide- and apatite-rich modally layered rocks in the lower part of the Bjerkreim-Sokndal Layered Intrusion in the Rogaland Anorthosite Province. The area is conventionally denoted MCUIB-e and defines a sequence of apatite-, ilmenite- and magnetite-bearing gabbronorite which may be followed from the farm at Åsen to Bjerkreim. The area is densely covered and the sequence only rarely exposed. The poor exposure makes it difficult to confidently assess the persistency and aerial extent of the MCU1Be target area. However, the overall similarities observed in profiles across the zone in terms of layering and mafic index do suggest that a prominent apatite-, ilmenite- and magnetite-rich zone exists. The zone varies in thickness from 15-20 to 60 m and is likely to be laterally continuous for at least 3 km wedging out gradually to the north and south.

This locality lies to the north of Berse lake and the zone is densely overgrown. It is therefore difficult to obtain a continuous impression of the extent and potential of the zone. The profile contains prominent sequences dominated by melanocratic apatite-, ilmenite- and magnetite-rich gabbronorite in intensely layered cumulates. The sequence here is not as extensive as at Åsen (< 50 m) and both the zone and the layered sequence tend to wedge out on approaching Bjerkreim.
