Abstract
A study was made of the radioactivity and petrology
of specimens from nine areas in northern Saskatchewan. The
specimens studied ranged in composition from granite and
pegmatite to diorite, and represented both areas of radioactive
mineralization and areas of no known radioactive mineralization.
It was found that structure was the most important control for ractioactivity with the highest radioactivity being
confined to the margins of the granitic bodies.
In two of the areas studied there is a direct relationship
between the radioactivity and the microcline content of
the rocks. The explanation suggested for this is that both are
deposited by the last phase of the megmatic solutions.
A general hypothesis is suggested that the granites
from areas of radioactive mineralization are pronouncedly more radioactive than granites from areas of no radioactive mineralization.
The study of the composition of plagioclase from
radioactive pegmatites of Charlebois Lake with the flame spectrophotometer when compared with the optical determinations
gave inconclusive results.
