Soil formation in archaeological pits and adjacent loess soils in Southern Germany

The soil formation in a number of pits on a neolithic excavation was compared with that in adjacent loess soils (Hapludalfs) under forest and arable and in Bavaria, Southern Germany. The differences between the soils under consideration were mainly characterized by micromorphological quantification of the illuviated fine clay. In the archaeological pits the amount of illuviated fine clay proved to be nearly twice as much as that in the undisturbed soils. The amount of illuviated coarser matrix components (fine and coarse clay and fine silt) in the neolithic pits did not differ significantly from that in the natural soils. The large amount of illuviated fine clay in the pits was ascribed to the presence of potash during the period of their formation. The formation of coarse grained illuviation cutans was related to deforestation, after which illuviation of the fine clay decreased in intensity and came to a stop.     

Hydraulically fractured: Unconventional gas and anthropology (Respond to this article at http://www.therai.org.uk/at/debate)

The predicted increase in unconventional gas production is set to change global energy and concomitant geopolitical relations. The scale and required infrastructure of unconventional gas extraction result in profound changes in the landscape where extraction and processing take place. Widespread public concerns about the impacts of this industry have emerged, particularly with regard to fracking, surface and subterranean water contamination, air pollution and a host of other environmental issues, as well as social impacts and health risks. This article sets out some of the emerging anthropological engagements with unconventional gas and fracking, including analyses of materiality, politics, discourses, rights, risk and knowledge.
