Many areas around the world such as the Mediterranean region have been inhabited without interruption for thousands of years. This is the case of the city of Barcelona (Spain), where remains of human settlements dating from pre-Roman times until the present have been found. A detailed geological mapping of the area occupied by the city of Barcelona raises a number of questions about the Holocene stratigraphy affected by human activity. In the old urban and surrounding areas most of the sedimentary deposits accumulated during settlement result from human interactions. Thus, new anthropostratigraphic units are proposed. The sedimentary deposits and the infill of rock excavations due to human presence may be divided into three categories: Natural lithoanthropogenic units (NAU) when their formation is not directly affected by anthropogenic activity but these contain artefacts of human origin. Induced lithoanthropogenic units (IAU) when natural processes together with human actions produce sedimentation or erosion due to natural phenomena; Constructed lithoanthropogenic units (CAU) when sedimentary accumulations and sharp contacts result from direct human activity. ResumenA lo largo de todo el globo terrestre, existen muchas zonas como la región mediterránea que han sido habitadas ininterrumpidamente durante miles de años. Este es el caso de la ciudad de Barcelona donde se han encontrado restos de asentamientos humanos desde los tiempos pre-romanos hasta la actualidad. Un mapa geológico detallado de la zona ocupada por la ciudad de Barcelona plantea una serie de interrogantes sobre la estratigrafía del Holoceno influenciado por la actividad humana. En la zona urbana antigua y en áreas circundantes, la mayoría de los depósitos acumulados durante el asentamiento se han producido por las interacciones humanas. Por tanto, se proponen nuevas unidades antropoestratigráficas. Los depósitos sedimentarios así como los rellenos de las ISSN (print): 1698-6180. ISSN (online): 1886-7995

“…Distinct changes would occur during the paludification and disappearance processes because of continuous interruption triggered by human activities. Numerous studies have been conducted with different emphases, such as sustainable uses of lake resources (Zalewski, 2000;Cruickshank and Grover, 2012;Pavri et al, 2013), water or sediment pollution in lakes by heavy metals and persistent organic pollutants (Smol, 2008;Jernström et al, 2010;Schmid et al, 2010;Bai et al, 2011), lake eutrophication induced by the mass input of nutrients (e.g., nitrogen and phosphorus) (Paerl et al, 2011;Yuan et al, 2011;Schindler, 2012;Søndergaard et al, 2013), and lake siltation and marsh development with respect to natural and/or anthropogenic activities (Xue et al, 2008;Brauneck et al, 2012;Kirwan and Murray, 2012;Noe et al, 2013).…”

Radionuclide dating techniques characterized by 137 Cs and 210 Pb ex have recently been applied in the study of lake sediments around the world. In this study, a chronological series of sediment cores was established based on 137 Cs and 210 Pb ex analyses along with the evaluation of sediment properties, such as particle size distribution, total organic carbon (TOC), carbonate content, and acid-insoluble residue, to study sediment accumulation rates, sediment sources, and responses to human activities in the Jiuzhaigou National Nature Reserve in southwestern China. In terms of the particle size distribution of sediments, silt content was the highest, and clay and sand contents were relatively low. The sediments displayed high TOC contents because of the significant amounts of vegetation grown in the lakes. The carbonate content was also high due to the overall geological background of carbonates in Jiuzhaigou. Carbonate content tended to decline from top to bottom in the sediment cores, whereas the acid-insoluble residue tended to increase. These results suggested that the depth variation of the environmental parameters of the sediments in two lakes in Jiuzhaigou would correspond to each other. The results indicated that the sediment rate of Jiuzhaigou was generally high with strong siltation, indicating that serious soil loss was induced by intensive human activities in the basin over the past decades. The increases in the mass accumulation rate, contents of acid-insoluble residue, and mean particle size during the periods of 1840-1900s, late 1930s-early 1950s, 1966-1978, and 2003-2006 revealed the occurrence of severe soil and water loss as a result of extensive agricultural expansion, large-scale deforestation, and road construction in Jiuzhaigou. The deposition rate and the properties of lacustrine sediments could reflect the significant impact of human activities on lake sedimentation during Jiuzhaigou′s history.
