Abstract

The Nålneset Peninsula section of the Kongsfjord Formation, Finnmark, northern Norway, allows comprehensive bed-by-bed correlation in a series of high-resolution measured sections. The outcrop is composed of high net-to-gross sheet sandstones that are interpreted to have been deposited in a channel-lobe-transition environment (Drinkwater, 1995). This section was previously recognized as forming the inner-fan depositional environment of a major submarine fan (Pickering, 1981), which is preserved at the base of a 3.5-km (2.1-mi)-thick overlying section. The outcrop section illustrated here is one detailed part of the oldest, lowermost part of the Kongsfjord Formation, which shows numerous features representative of the typical channel-lobe transition. It is characterized by a hierarchical arrangement of laterally extensive, often compensating, high and low net-to-gross sheet elements that are tens of meters (many tens of feet) thick. Abundant evidence of extensive dewatering, rapid deposition, internal scouring, bed amalgamation, sediment bypass, and reworking are present (Drinkwater and Pickering, 2001). Separating these elements are thinner, finer-grained sheet elements that are characterized by low-density, strongly parallel- and thinly bedded, layered, low-density turbidites. These are composed of typically silty and very fine-grained sandstone. Outcrop quality allows extensive correlation of both types of sheet elements within the outcrop section. A high-resolution example of these sheet elements has been documented and quantified in this example. The Nålneset section is illustrative for sheet systems in confined-basin environments, or in fan environments at a scale an order or more below that of the fan's gross morphology. Outcrop limitations preclude an absolute determination of the full depositional environment.
