“…At present, this activity is primarily responsible for the relief modification and sediment transport seen in the area, as well as the significant environmental degradation, particularly around urban centres (Giménez et al, 2002;Rivas et al, 2006;Hurtado, 2015). Similar effects of soil mining have been described across various parts of the world (Lal, 1997;Yadav, 2003;Singh and Asgher, 2005;Haack and Khatiwada, 2007;Zhang and Fang, 2007;Gupta and Narayan, 2010;Santhosh et al, 2013).…”

“…In the ceramic industry, soil mining has been performed for a long time and remains a common practice in other parts of the world (Mbumbia et al, 2000;Singh and Asgher, 2005;Zhang and Fang, 2007;Ngon Ngon et al, 2009;Nzeukou et al, 2013;Santhosh et al, 2013). The possibility of using sediments as raw materials for brick making has also been explored (Bhatnagarjm et al, 1994;Chiang et al, 2008;Samara et al, 2009;Mezencevova et al, 2012;Cappuyns et al, 2015).…”

The nature and amount of sediments in various lakes, intermittent swampy areas and river sectors in the humid Pampa (Buenos Aires Province, Argentina) were analysed. The aim was to determine whether recent sediments in such environments could serve as an alternative resource to the brick industry, for minimising the current, high environmental impact of soil mining. Sediment sequences were obtained, and the thicknesses of the upper sediment layers, corresponding to the suballuvial (approx. 1400-700 years BP) and alluvial (approx. 250 years BP to present) were determined. Sediment samples were collected and analysed for grain size and Atterberg limits. Suitable sediments were then selected to determine the optimal brick materials and their technical properties. Similarly, control bricks were prepared with ceramic pastes of local industries. The results show that the quality of the former is similar or superior to that of the latter. The initial estimates of the available resource indicate a long-term supply for the industry. Estimates of the current sedimentation rates indicate that resource renewal might occur at a rate comparable to current consumption. The sedimentation rates have increased significantly in the past two centuriesmore so in the past few decades (the Anthropocene?)with increasing human modification of geomorphic processes. If the results presented here are confirmed, a highly sustainable model can be implemented in the brick industry.
