Extremely rare. Probably from the second oxidation zone.
- 2nd Oxidation Zone
Paragenetic and General Notes
Larsenite occurs as white needles (to 1 mm) on willemite, from which it is distinguished with difficulty (Gebhard, 1999).
Keller and Bartelke (1982) described radiating masses of very fine, dull white larsenite fibres (to 2 mm), with queitite and alamosite. The association with alamosite implies that this is likely a second oxidation zone assemblage.
