The groundhog River Block (GB) forms the central segment of the Kapuskasing Structural Zone a fault-bounded belt of Proterozoic crustal uplift in the southern Superior Province. Dykes adjacent to the GB carry a magnetization (D = 11°, I = 26°, α95 = 27°, N = 3) that is characteristic of 2.45 Ga Matachewan dykes. However, within the GB, dykes and high-grade gneissic host rocks carry a steep positive magnetization (D = 295°, I = 83°, α95 = 12°, N = 9) that also partially overprints the dykes immediately outside the GB. The boundaries between the contrasting paleomagnetic signatures coincide with boundary faults and changes in paleopressure that define the GB. The steep magnetization in the GB was acquired during uplift and cooling close to the time at about 1.95 Ga when a virtually antiparallel remanence of similar origin was being formed in the Chapleau Block, the southern segment of the Kapuskasing Structural Zone.

Worthy of celebration is the contribution made by Itumeleng Mosala (hereafter Mosala) to the Black Methodist Consultation, the theological community in Southern Africa, and the Black Consciousness Movement. This article attempts to give theology its world, feet and hands in the person of Mosala. The article departs from the narration of the history of Mosala. It locates Mosala within township life and Old Testament scholarship. Furthermore, the article searches for suitable and effective weapons of intellectual struggle in light of Mosala’s life. The aim of this article is to celebrate the indelible footprints that Mosala made as he communed with black people.

History Of Use

The Lamiaceae is undoubtedly an important plant family, having a rich history of use that spans the globe with many species being used in folk medicine and modern industries alike. Their ability to produce aromatic volatile oils has made them valuable sources of materials in the cosmetic, culinary, and pharmaceutical industries. A thorough account of the taxonomic diversity, chemistry and ethnobotany is lacking for southern African Lamiaceae, which feature some of the region’s most notable medicinal and edible plant species. We provide a comprehensive insight into the Lamiaceae flora of southern Africa, comprising 297 species in 42 genera, 105 of which are endemic to the subcontinent. We further explore the medicinal and traditional uses, where all genera with documented uses are covered for the region. A broad review of the chemistry of southern African Lamiaceae is presented, noting that only 101 species (34%) have been investigated chemically (either their volatile oils or phytochemical characterization of secondary metabolites), thus presenting many and varied opportunities for further studies. The main aim of our study was therefore to present an up-to-date account of the botany, chemistry and traditional uses of the family in southern Africa, and to identify obvious knowledge gaps.

Church Tradition

The use of credentials in an ecclesiastical context is a means of assuring that a minister is who he or she claims to be and is therefore trained and qualified to exercise ministry within a particular church tradition as determined by individual denominations. The concept and use of credentials has developed over time. Using primary sources in the main, this article examines the use of credentials as a tool for ‘inclusion’ or a means of ‘exclusion’, or both, in the history of the largest Presbyterian church in Southern Africa and its predecessors. The research question under study is to what degree, if any, were credentials used to control ministers and to cleanse and purify the church of radical – such as anti-apartheid – elements?
