MINES AND ARCHAEOLOGICAL SITES IN SOUTHERN AFRICA by ADAM VICTOR KIEHN (Under the Direction of George A. Brook) ABSTRACT Specularite ore was collected from five prehistoric mining regions in Botswana and the Northern Cape Province of South Africa and 172 samples were analyzed by instrumental neutron activation analysis.
Magnificent automorphic hematite crystal with beautiful spiky terminations from the N'Chwaning mine in South Africa. Let's not forget that the N'Chwaning manganese mines have provided world-class hematite crystals. This one is …
Mining reports and historical logging document predominantly typical high-grade and hematitic ores (e.g. Fig. 7 a), although these may also be associated with well-developed lenses of low-grade dolomite-hematite and calcite-hematite ore (e.g. Smit and Beukes, 2016). Martite and microplaty hematite, in relatively low-grade ores, are largely ...

At depth, the high-grade hematite ores interfinger with low-grade dolomite-hematite and calcite-hematite ores. Iron oxides (martite, microplaty hematite) present in these low-grade ores are texturally indistinguishable from those in the associated high-grade ores, ie ore formation is genetically associated with carbonate metasomatism.
