Abstract: Abstract Field relationships, textures, compositions and U-(Th)-Pb dates for minerals from the niobium‑yttrium‑fluorine (NYF-) Stetind Pegmatite in the 1.798 Ga Tysfjord granitic gneiss in Norway are described. The pegmatite has a sub-horizontal orientation and anisotropic mineral… read more here.
