✪ Vajdakite (TL)

Formula: [(Mo6+O2)2(H2O)2As3+2O5] · 3H2O

Type Locality:

Habit: Crystals are lath shaped, and their size varies from 0.1 to 0.5 mm. Their termination is highly irregular with needle-like features

Colour: yellow-green to gray-green

Description: The best specimen from the original was a 4x5 cm with crystals of vajdakite up to 2 mm with a coverage of vajdakite covering about 1x1cm. There were about three such specimens. Crusts of closely packed smaller crystals were more common. The find consisted of about 20 specimens from the size of a thumbnail to about 4x5 cm. The original find was in a tunnel with granite walls and the portion of the tunnel where the vajdakite was found has collapsed (Joseph Vajdak, personal communication 2002.)
