Marine kvartær-fossiler fra Seimsjøen i Sør-Odal.

Abstract

The locality is situated 67 km NE of Oslo centre, at the outlet of Seimsjøen, the southwestern extension of Storsjøen lake (water level 130 m above sea level). Borings were undertaken by the Norwegian Geotechnical Institute, and two of them have been micropaleontologically investigated. The core meterial consists of silt, sand and clayey silt. The surface at boring1, on tha NW side of the outlet, lies 133.5 m above sea level, and bedrock was encountered 25 m below the surface. The coring goes down to 18 m below the surface. Between 9 and 16 m the following species of marine Foraminifera occurred: Quinqueloculina seminulum (LinnÅ) (1 spec.), Pyrgo williamsoni (Silvestri) (2 spec.), Nonion labradoricum (Dawson) (3 spec.), Nonionella turgida (Williamson) (1 spec.), Elphidium clavatum Cushman (37 spec.), Elphidium incertum (Williamson) (1 spec.). Boring 3 is located on the south side of the outlet from the lake. The surface is situated 133.0 m above sea level, and bedrock was encountered 18 m below the surface. The core material consists of silt and sand down to 14 m, and silty clay further down to 16 m. Samples were not taken below this depth.
