Quartz veins with lazulite are embedded in the Carnic sericitic phyllites and metaconglomerates. The primary rocks were a succession of sands, clays and conglomerates, metamorphosed to the greenschists facies during a tectono-metamorphic event developed between 27 and 8 My.
Inside these rocks and the quartz veins, there are kyanite, pyrophyllite, chlorite and hematite; lazulite is present only inside some among them.

The mineralized quartz veins in phyllitic rocks and metaconglomerates are located on southern side of Mt Folgorito, in a locality named "Strinato" along the road from Strettoia Village that reaches Cerreta S. Nicola.
