Rutile as Sagenite Pseudomorphs after Ilmenite
Arzo Ridge, Robiei, Val Bavona, Ticino, Switzerland

Straw-yellow to bronze-colored rutile as a lattice-shaped "sagenite" on milky-white albite (in pericline habit), with dark green clinochlore and silvery muscovite flakes on graphitic mica schist. This rutile displaced a large former ilmenite table in the base zone of the large disthene quartz/clinochlore fracture No.201 on the Arzo Ridge. It yielded particularly attractive sagenite specimens in August and September 2022.
