abstract = {Copper objects from the Lower Hungarian mining towns of Neusohl and Herrengrund (today Banská Bystrica and Špania Dolina in Slovakia) enjoyed a particular popularity among travelers and collectors in the 17th and 18th centuries. While most of these objects are rather unspectacular on the first sight (therefore they are often only mentioned in passing), a closer consideration of the economic and epistemic contexts in which they originated will prove the contrary. Through the example of these objects, I will illustrate the connection between mining and alchemy and I will further reveal the material imaginaries of iron on a material, discursive and practical level.},

abstract = {In the Aegean-type wall paintings of Tell el-Dabca, Egypt, steatite was used as a constituent of the white colour. Previous research has revealed that the use of talc as a pigment can be considered as an important marker of Aegean craft traditions. In this case study it is therefore of primary importance to trace back the origin of this particular mineral and rock, especially since it can be found in several locations in the Mediterranean including Egypt, Crete and Cyprus. While there is still no generally valid strategy to assign archaeological objects made from this particular material to a specific steatite deposit, the physio-chemical characterisation of the latter mostly relies on the measurement of Rare Earth Elements (REE's) or other methods focusing on the chemical composition of the whole rock. In this paper, a new way to determine steatite origin is presented using electron microprobe characterisation of spinels inside the steatite matrix. Those tracer minerals can not only be the source of information concerning the formation of steatite but their core composition can in some cases also reflect the primary composition of the precursor ultramafic rock. This method focuses on the geotectonical history and genesis of the protolith rather than on steatite's chemical composition. The results reveal the spinels to have similar characteristics to those of supra-subduction ophiolites in the Egyptian Central Eastern Desert. We suggest a correlation between gold and steatite exploitation and thus the use of local raw materials for the creation of the Aegean-type paintings.},

abstract = {The current article discusses the Bronze Age metal evidence in Central Asia based on a vast study of metals of Kazakh origin in order to better understand what Chernykh once called the West-Asian-Metallurgical Province (WAMP). Based on typological studies it became obvious that typologies do not sufficiently help to understand the distribution patterns of Bronze Age metals in regard to their social  nor their economic background. The authors therefore propose an anthropological and theoretical approach that allows the  exploration of the practice of exchange within steppe communities based on provenance studies of metals using elemental and Pb-isotope data. These data have been analysed within a research project carried out with Kazakhstan partners between 2004 and 2014.  For the first time, a selection of data are presented that support some of the general interpretations of exchange modes between the  Petrovka Early Bronze Age and the Late Bronze Age. Especially during the second millennium, it seems that the exchange pattern of  metals had changed from single high valued items to a larger scale trade, which included metal transport as well. It is suggested that  although the practice of exchange modes between the steppe communities change to larger scale metal exchange during the 2nd half  of the 2nd millennium BC, most of the social background still remained similar in comparison to the earlier periods. },

abstract = {Mollisols are of major importance for food security worldwide but are increasingly degraded by soil erosion. Mollisols in Northeast China have been converted into agricultural use only since the 19th century, but gullies are widely distributed. Gully erosion history, rates, and causes in this region remained unclear. We chose a study area with landforms and land-use history typical for the central Mollisol region of Northeast China to estimate the initiation years and rates of gully erosion from 1968 to 2018 using aerial and satellite imageries. The outlet fan deposits of a large gully system were dated by Cesium-137 (137Cs) and artifacts. Local farmers were interviewed to verify the results. Gully volumes were measured by a structure-from-motion technique using photos taken from an unmanned aerial vehicle. Our results showed that gully systems had already appeared on the steep slopes and along unpaved roads in 1968. They had become larger and more complex in 2018 by the upslope retreat of the main gullies and side gully formation. Gully incision started in the 1950s and 1960s when the original grassland and forest were completely converted into arable land. From 1968 to 2018, the gully density increased from 1.2 to 2.3 km km−2 and the gully heads retreated at speeds from 1.5 to 2.5 m yr−1. The soil loss from gully erosion ranged from 25.7 to 44.7 Mg yr−1 ha−1. These data demonstrate the severity of gully erosion in the Mollisol region of Northeast China and underline the importance of appropriate countermeasures.},

abstract = {Terracing of hillslopes is usually regarded as an effective measure to control soil erosion. Although it is often stressed that proper terrace construction and regular terrace maintenance are of great significance to prevent erosion on terraced hillslopes, examples of terrace-induced gully erosion are scarce. Field observations on terraced and partly abandoned hillslopes in the Black Soil Region of Northeast China, a region heavily affected by gully erosion since the middle of the 20th century, indicated that gully formation might be caused by terraces. In order to understand the impact of terracing on gully erosion, we selected several gullies to investigate the cause and timing of their triggering. We used a combination of field mapping, high-resolution digital terrain models, multi-temporal aerial photograph interpretation and interviews with local farmers. Our results showed that several gullies developed after terracing. Improper terrace design caused runoff concentration along terraces and ridges with mean inclination of 3.8%, which resulted in gully incision due to overtopping of terraces at low spots or due to the uncontrolled release of concentrated flow to adjoining unterraced hillslopes. The same processes are responsible for the persistent gully activity after abandonment and vegetation recovery. Furthermore, we showed how terraces affected gully morphology. Finally, we suggested appropriate countermeasures to stop further soil loss and land degradation on abandoned terraced hillslopes in NE China. Our findings are important as they demonstrate how poorly designed terraces may not only be ineffective but may even aggravate gully erosion.},

abstract = {Urban ecosystems perform a distinctive metabolism appropriating fundamental materials and energy resources from other ecosystems. This appropriation enables a productive circularity which sustains the material production of urban space: urbanisation. Upon entering the urban ecosystem, the material fluxes are processed by human labour to be consumed, exchanged and accumulated. The appropriation of raw materials and the further production of technomass are entangled processes along a complex material circulation, sustained by internal metabolic processes of production, consumption, transformation and accumulation. The overall process couples several ecosystems along a metabolic urban network (MUN), a large-scale interconnected metabolism of urban and non-urban ecosystems. Long and short distance metabolic interactions configuring a huge space of flows from which distinct urbanisation patterns arise. The extended urbanisation, differential urbanisation, accumulative urbanisation, cascade urbanisation and speculative urbanisation are historically and ecologically determined. The MUN is an asymmetric spatiotemporal exchange structure to and from which matter, energy and information flow, producing profound socio-ecological asymmetries in a global range of dispersed urban tissues. The MUN is the vortex where the planetary processes of ecological and social deterioration is driven. The MUN is an analytical device to unveil urbanisation as a socio-ecological process of colonisation of urban and non-urban ecosystems.},
