Dear Ralph Bottrill and Piergiorgio Rossetti,
I am interested in the occurrence of adularia in magmatic rocks and related
hydrothermal veins, as you pointed out. Are there any publications related
to this topic?
It seems to me adularia (and in particular Ba-rich adularia) is a
low-temperature hydrothermal mineral, usually associated with massive
sulfide deposits.
Cheers,
Shao-Yong

In my experience, also adularia can be almost uniaxial. In Oligocene
magmatic stocks from the Italian Western Alps, adularia occurs both as
euhedral crystals within hydrothermal veins and as replacement product after
magmatic K-feldspar and in part plagioclase.
Best regards
