General Notes
Erythrite was listed as an "exceptionally rare" mineral at Tsumeb by Lombaard et al. (1986), a source which should lend some credibility to its occurrence. However, Keller (1984) makes no mention of it.
Gebhard (1991, 1999) included erythrite in his list of Tsumeb minerals but with no further comment while Von Bezing et al. (2016) stated merely that erythrite has been identified at Tsumeb, citing Gebhard (1991) as the source. Mindat does not include erythrite in its listing of Tsumeb minerals (www.mindat.org; accessed December 2022).
The occurrence of erythrite at Tsumeb is considered questionable pending confirmation.
