Paragenetic and General Notes

Gebhard (1999) reports that a single specimen is known. However, the absence of marcasite from lists published by Strunz et al. (1958) and by Lombaard et al.(1986) suggest that marcasite was not encountered in any of the numerous ore microscopy studies undertaken by the Tsumeb Corporation.
