...D. Rammlmair; A. Mogessie; F. Purtscheller; R. Tessadri Abstract Högbomite and zincian högbomite are reported for the first time from a Mg-Fe-AI-rich layer within the serpentinite unit of the Vumba schist belt, Botswana. The zincian högbomite in one sample is a secondary product of a Zn-bearing...

... Abstract Meta-exhalites consist of a variety of rock types including iron formation, coticule (garnet-quartz rock), tourmalinite, quartz-gahnite rock, apatite-rich rock, zincian staurolite-bearing rock, and barite-rich rock. Such lithologies may be spatially associated with a diversity of ore...

... into the metamorphic environment. Spry and Scott (1986) observed that Zn-bearing spinels are found in many rock types associated with metamorphosed ore deposits. Grew (1998) reported Zn-rich hercynite (10.95 wt.% ZnO) and associated zincian oxides, musgravite and hogbomite, in surina-mite-bearing aggregates from...
