Terland, Eigersund, Rogaland, Norge
Oxide- and apatite-rich modally layered gabbronorite in the Bjerkreim-Sokndal Layered Intrusion in the Rogaland Anorthosite Province. The stratigraphic sequence, to wich the Terland N deposit belong, is conventionally denoted MCU3-e and may be followed along strike from Rappstad in the southern extension around the hinge of the Bjerkreim lobe to Ualand in the northeastern extension - a total distance of approximately 25 km - but is absent for about 8 km in the central part of the intrusion, due to extensive dyke emplacement (the Lomland Jotunitic Dyke). The thickness of the zone is variable, both stratigraphically and in exposure, decreasing from up to 300 m in the central most part to around 50 m on the flanks. Although the presence of a persistent melanocratic apatite- and oxide-enriched sequence has not been fully documented (partly due to lakes and sedimentary cover) in the MCU3e, melanocratic sequences are at least very frequent.
The northern flank is overall more melanocratic, and extensive sampling has been performed at Terland, Teksevatnet (west end), Bilstadvatnet and Vasshus. At Terland N. the MCU3e zone has a total stratigraphic thickness of 300 m
