On the #dansk GEUS portal there's a lot of information on the survey that created this borehole. It was a combined geologic and drinking water (for deep water aquifers) survey.

I looked at it with a friend who's a environmental consultant. However I am still lost on why spectral gamma data was collected from each parallel borehole. I guess one can use it to determine clay / minerals / salt composition. But is it used for a broader purpose?

Any #geoscientists / #earthscience people here?
