NGU conducted an airborne magnetic and radiometric survey in Kvinesdal and Sirdal area in October to November 2013, July and October to November 2014 as part of the MINS program (Mineral resources in Southern Norway). This report described and documents the aquisition, processing and visualization of the recorded datasets. The geophysical survey results reported herein are from 14600 line km, covering av area of 2920 km2.
This survey was carried out in cooperation with the Norwegian Public Roads Administration (Statens vegvesen) to aid and supplement the construction of a major tunnel in Arsvågen, Rogaland. Essentially, this work follows up ROGFAST project which also included resistivity measurements at the island of Kvitsøy just south of the new survey area. It is also in close connection to another NGU project which tested the efficiency of 2D resistivity method in marine environments.
Kvernsteinsbruddet på Nord-Talgje dekker til sammen et område på 20 600 m2. Bruddet er naturlig delt inn i fem felt merket fra A til E på grunn av topografiske forhold og ulike kulturminner og teknikker. I bruddet er det utelukkende tatt ut dreiekverner; hovedmengder er håndkverner med diameter mellom 46/47 cm og 56 cm men der er også flere uttak av vasskverner, der diameteren varierer mellom 58 og 120 cm.
