Drøbak 1814 II. Beskrivelse til hydrogeologisk kart M 1 : 50 000 (med fargetrykt kart).

The map gives a total evaluation of the water yield capacity from the best aguifers, either bedrock or superficial deposits, marked by colours from yellow to bluish green. The map also deicts topography, bedrock geology, constructions and surface hydrology. In the Precambrian rock, major joints along N 30°, N 120° and partly N 0°, N 40° and N 160° trends are considered to be best. The water yield capacities of the different Precambrian rocks and the Drammengranite, which together occupy almost the entire map area, are very much the same, except for the amphibolites and metagabbros which yield less than half of the others.

This volume of NGU Special Publication presents some of the ongoing research at the Geological Survey of Norway and shows how geology and geological knowledge influence many areas of society. The global demand for geological resources is on the rise, and knowing where to look for these resources is becoming increasingly more important. In addition, quantifying these resources is vital to ensure present-day as well as future supplies. As society and technology evolve (cf., the Stone Age-, Bronze Age-, Iron Ageprogression) so does the demand for geological resources. A sagacious assessment of geological resources therefore requires a broad, research-based approach.
