Extended analysis of data for detection of heavy minerals
Spectral Natural Gamma-ray logs have been run in two water supply borings at Skjern. The log data have been examined by a new technique - Noise Adjusted Singular Value Decomposition - in order to get a detailed and reliable picture of the distribution of uranium and thorium gamma-rays from heavy minerals. The new technique proved to be significant better than the conventional windows techniques.
