Description
Melke Formation
NameThe Norwegian word for milt or soft roe. This unit corresponds to the informal Engelvær Formation (H2-1).Well type section6506/12-4 (Statoil), coordinates 65°12'46.97"N, 06°43'30.37"E, from 3979.5 m to 3863 m (Fig 4.21) . One core, 8 m recovery, including formational base.Well reference section6407/2-2 (Saga Petroleum), coordinates 64°59'39.64"N, 07°31'53.08"E, from 2461 to 2417 m (Fig 4.23) . One core, 2 m recovery, including the base.Thickness116.5 m in the type well, 44 m in the reference well.LithologyDominantly claystone, with siltstone and limestone interbeds and stringers of sandstone. The claystone is dark grey to dark brown and slightly calcareous.Basal StratotypeThe base is defined by a sharply increasing gamma ray response at the contact between the underlying sandstones of the Garn Formation and the claystones of the Melke Formation .Lateral extent and variationThe formation was deposited throughout the Haltenbanken-Trænabanken area and is locally absent on structural highs. The formation may attain thicknesses of several hundred metres in down-flank basinal situations. The formation also shows lateral variation in lithology, being more silty or having more frequent limestone beds in some areas. Deposition of the unit's mudstones commenced earlier on Trænabanken than elsewhere (Fig 4.6) .
The unit subcrops beneath the Quaternary on the eastern part of the Trøndelag Platform as evidenced by several shallow cores (Bugge et al. 1984).AgeBajocian to Oxfordian.Depositional environmentThe Melke Formation was deposited in an open marine environment.CorrelationThe Melke Formation is comparable to the Heather Formation of the North Sea. The upper parts of the Melke Formation are time equivalent to the Fuglen Formation in the Hammerfest Basin.Source-
