ABSTRACTThe ability of hunting and gathering populations to adopt herding forms of subsistence constitutes the crux of a long-standing debate in southern African archaeological and anthropological scholarship concerning the spread of livestock to the subcontinent. This article takes as a detailed case study the subsistence strategies of the nineteenth-century ǀXam Bushmen of the Northern Cape (South Africa), extracted from a transcription of the entirety of the Bleek–Lloyd Archive. It focuses on ǀXam characterization of and relationships with the various domesticated species that shared their Karoo landscape, and asks whether these relationships differ markedly from their conceptions of non-domesticated animals. Turning to the wider context of hunter-gatherer engagements with domesticates, the article concludes by proposing that, for the ǀXam, domesticated fauna were part of a spectrum of differentiated resources, and did not entail an interaction with a wholly alien suite of new demands.

This article describes the screening, ranking and characterization of ultramafic and mafic rocks in southern Portugal for mineral carbonation as an alternative to conventional CO2 storage in sedimentary rocks. A set of criteria including mineralogy, structure, surface area, distance to CO2 sources, expected volume, and socioeconomic conditions was applied to screen ultramafic and mafic rock massifs in the Alentejo region, southern Portugal. Ranking of the massifs indicated that the plutonic massifs of Sines and of Torrão‒Odivelas were the most promising. A characterization was made of the Sines massif, a subvolcanic massif composed mostly of gabbros and diorites, located immediately adjacent to the CO2 sources and outcropping along 300 km2 onshore and offshore. These studies confirmed that these rock samples exhibited the appropriate mineralogical and geochemical features, but also indicated that the secondary porosity provided by the fracture patterns was very small.
