Turbidity in alkali feldspars from granitic pegmatites

open access: yes, 1994
Alkali feldspars from pegmatite of Brazil and Spain have microscopic to submicroscopic inclusions giving a >turbid> and >clouded> appearance. Inclusions are isotropic, irregular and spatially associated with patch/vein lamellae in network and/Or isolated masses. Inclusions have no detectable lines in XRD and microprobe analyses show strong variability:
