“…From the 4th to the 2nd millennium BC, approximately 5 m of alluvium were deposited at Ghabristan, followed by only about 1.5 m in the subsequent four millennia. Further investigations are needed to link this slowdown of deposition (from roughly 2.5 mm yr À1 to 0.4 mm yr À1 ) with possible environmental changes (Weiss et al, 1993;Bar-Matthews et al, 1998;Lucke et al, 2005). As stated above, there appears to be a settlement hiatus in the Iranian Plateau during the early to middle Bronze Age and further investigations at the Sagzabad Cluster may shed more light on this period of Iranian prehistory.…”

“…In Ma’rib (15°25′N, 45°21′E), north eastern Yemen, 15 soil profiles were described in 2006 and 2007, and the substrates were classified using a prototype of the key presented in this paper. Additionally, 20 soils from Al‐Qafr (14°07′N, 44°05′E) in the southern Yemen highlands (Pietsch, 2005) and examples from Yarmouk (32°42′N, 35°52′E), Jordan (Lucke et al , 2005; Schmidt et al , 2006), were examined in order to apply the proposed soil substrate classification to other soils in semi‐arid regions on the Arabian Peninsula. As most of the soils are layered, the soil profile descriptions were completed by identifying the respective substrate layers, by means of particle‐size ratios (Altermann & Fiedler, 1978), XRD‐data (Allmann, 2003) and colours (Semmel, 1988).…”

“…In addition, the detritus and CaCO 3 contents increase in the topsoil and decrease steadily towards the profile bottom. Part of the bigger stones at the surface could resemble the remains of ancient field borders, as archaeological sites are located close by (Lucke et al , 2005). Due to the large clay content, soils might start mass‐movement when wet, leading to a filling of depressions on karst plateaus.…”

The World Reference Base for Soil Resources and the FAO Guidelines for Soil Description are tools to identify, describe and classify a soil by diagnostic horizons, diagnostic properties, diagnostic materials, and other soil features. While bedrock and residual fragments can be defined by their lithology and abundance, the parent material of soil formation is not clearly classified. Therefore a substrate classification was implicated in descriptions of layered soils, because these consist often of allochthonous, polygenetic and heterogeneous substrates. Results of soil investigations in Yemen developed into a substrate classification key for parent materials that focuses on parameters of substrate variety. Primarily, the present approach was developed to describe layered soils on the Island of Socotra, but it is assumed to be valid for any semi-arid region in the Tropics and Subtropics. To assess the operational reliability of the system, it was applied to classify parent materials of soils from Yemen mainland and Jordan. The classification key is partly based on the FAO Guidelines, and partly on the German Soil Mapping Guidelines. The substrate variety includes lithology, weathering intensity, stratigraphical unit and substrate form. Different substrate varieties within one profile are called substrate orders and closely relate to sedimentary bedding. The proposed classification key is based additionally on parameters such as geogenesis and relief position. It can be used separately from soil description. However, soil identification and description become more precise by using this classification system. This contribution should be understood as a first approach to an international substrate classification.

“…Other influencing factors, such as permanent parameters (seismology, lithology, relief), and variable factors (climate, hydrology, vegetation cover) have also an impact on sediment yield and erosion rates (e.g. Edwards and Whittington, 2001;Lucke et al, 2005;Dodson et al, 2004;Pelle et al, 2013;Vogel et al, 2016). These natural and anthropogenic factors are difficult to untangle (Berglund, 2003;Ackermann et al, 2014).…”

Lake sediments are sensitive to landscape changes and most of these changes seem to be modulated by land-use (anthropogenic factors) coupled to palaeoenvironmental/palaeoclimatic changes. In its detrital fraction, the lacustrine sediments record the history of soil erosion within its catchment via the inputs of clays and others detrital products. Within a Mediterranean context, the study investigates the upper sediments infilling the central part of the Amik basin in southern Turkey. This tectonic basin was occupied and exploited by modern human at least since 6000e7000 BCE. We focus on the clay mineralogy (x-ray diffraction on oriented aggregates) and magnetic susceptibility measurements (Bartington) of the sedimentary record in the area over the last 4000 years, to assess environmental changes in relation with the different land uses and/or weathering during the successive Bronze, Iron, Roman, Islamic/Ottoman and Modern civilizations. The clay fraction of Amik Lake sediments comprises smectite, kaolinite, illite, chlorite and chlorite/smectite mixed layers that are the inherited clay phases. A relative change in abundance and crystallinity and chemistry of illite attests that environmental conditions evolved in the Amik Plain from the Bronze to Modern Age in relation with climates and/or land-use changes. The history of the Amik Lake reveals different soil erosion episode. The most intense erosion phase occurred during the Bronze/Iron Ages as indicated by the clay and magnetic susceptibility proxies. The Roman period was an exceptional period with soil erosion products arriving from the watershed, probably due the water channelization. A reduction of soil erosion occurred during the post Roman period until nowadays. Significant pedogenesis transformations are evidenced, especially during the Islamic/Ottoman periods suggesting intense chemical weathering conditions related to climate change.
