... 3 –K–As 2 O 3 –Cl layer sequence in the structures of lucabindiite and gajardoite. Both cuatrocapaite-(NH 4 ) and cuatrocapaite-(K) occur as hexagonal plates, flattened on {001} and bounded by {100}, up to ~300 µm in diameter. The pyramidal forms {10 ℓ } and {01 ℓ } are present on some crystals...
