Geochemistry has a important role to play in Geological Survey activities in the 21st Century. However, as distinct from the 20th Century, environmental issues may eventually become more important than resource issues in sustainable development decision making; in fact this has already happended in some countries.
Geological mapping and interpretation has shown that the rocks in Berakvam operating quarry can be subdivided in four NW-trending zones, which continue at depth down to the northeast.
The Geological Survey of Norway is in process of compiling an inventory of hard rock aggregate deposits in coastal Norway. This report contains a catalogue of Norwegian coastal quarries presently in production, as well as potential production areas along the coast of southern Norway. 10.4 million tonnes of aggregates were exported to Europe in 2002, of which about 1.3 million tonnes was used by the offshore oil and gas industry on the continental shelf.
A three-phase conceptual glacial geological model for the Late Pliocene and entire Pleistocene period has been developed. The model explains variations in erosion in the Barents Sea in space and time and shows: The first phase (until ca. 1.5mill. years) was characterized by glacial erosion over the present land areas of Svalbard and Norway. Minimal, if any, erosion over present shelf areas. A transition phase (ca. 1.5 - ca. 0.5 mill. years) with glacial erosion over restricted areas.
NGU has conducted a hydrogeological assessment of a groundwater well which Best Kjøttprodukter AS is considering for the production of bottled water. This report forms the basis for approval by the local Food Control Authority to use the well for the production of bottled water.
Chephren's Quarry is one of the world's oldest hard-stone quarries. It is situated in the easternmost part of Sahara - covering nearly 100k2 of flat, hyper-arid desert, some 60 km west of Lake Nasser ( River Nile) and the famous Abu Simbel temple in the extreme south of Egypt.
This report presents the results from chemical, petrographical and mineral chemical analysis of a sample from Mugla Tepe, Turkey. The rock is a serpentinised dunite, the degree of serpentinisation is about 50% (LOI=6.63). The rock contains 44.2% MgO 7.8% FeO and has a total alkali content of 0.02% The primary rock has been a homogenous dunite. The present mineral content is: Olivine 83.0%, serpentine 11.7%, enstatite 4.5%, chromite 0.5%, and magnetite 0.3%.
This report contains the scientific program and abstract volume for the lectures and posters presented during the Alice Wain Memorial West Norway Eclogite Field Symposium. The lecture and field symposium, held in Selje from June 21st-28th, 2003, focuese on the dynamic processes of high- and ultrahigh- pressure metamorphism and exhumation of eclogites and associated rock tupes. The Symposum commemorates the outstanding to contributions to west Norway eclogite research by the late Dr.
This report is a guidebook for the field excursions conducted during the Alice Wain Memorial West Norway Eclogite Field Symposium held in Selje from June 21st-28th, 2003. Eskola (1921) drew attention to some of the aesthetically impressive eclogites and garnet peridotites that outcrop in the coastal region of west Norway between Bergen and Trondheim.
