SUMMARY ,
In numerous problems of
drUlini
geophysics theknowledge of the degree of clay content in rocks
seems 'to be necessary. Determination of clay
con-tent in r.ocks by means of gamma logging method is the main topic of the article. Based on ample data obtained in numerous examinations the author is of the Opinion that sandstone-clay and carbonate rocks (which do not contain admixtures of glauconite,
monacite 'and other chemical elements distinguished
by inexeased radioactivity) are characterized by an
increaS~ '~ .radioactivity with the increase in the
content of "clay material' and dispersion degree. As
concerns,' for example, the carbonl!lte rocks from
Grzyb6w, a close correlation exists between the
clay coJitent and
gamma
radiation intensity. Theauthor ·describes the method of gamma logging
ap-, plied ,in her investigations and suggests that the
application of, this method would allow us to
redu-:ce, on a large 'scale, the coring intensity, thus giving
considerable,
demase
in, the costs of drilling.o f()
