Val di Crana pegmatites, Val di Crana, Ossola Valley, Verbano-Cusio-Ossola Province, Piedmont, Italy

Since the late 1960s, several pegmatitic dykes embedded in acid meta-porphyrites (ortho-gneisses) and sometimes bearing uncommon rare-earth minerals, were found near Arvogno (middle Val di Crana, also known as Melezzo Brook Valley), a small village in the municipality of Toceno.

Some veins have been described, in the mineralogical bibliography, as individual (sub)-localities. They are:

— "Cortino & Fae" veins.

— "Strada per Arvogno" (Arvogno road) vein — currently covered by a concrete wall.

— "Pegmatite del Bosco" ("in the wood" pegmatite — also known as "Albertini pegmatite").

— "Pegmatite del Fiume" ("on the river" pegmatite) — currently buried under the river course (July 2010).

Despite having minerals in common, e.g. euxenite-(Y), all the above-mentioned veins have their own peculiarity concerning crystal morphology and the occurrence or abundance of individual mineralogical species.

Other minor veins, generally with simpler paragenesis are scattered in the area and, with a very active river flood and land-slide dynamic, there is potential for the discovery of new veins.
