Bobrov Ciencias de la Tierra alluvial paleosol human impact sedimentary sequences athropogenic materials Subatlantic landscape changes were reconstructed by correlating independent results of pedologicalstudies, pollen, phytolith, and micropaleontological analyses of flood plain soil-sedimentary andsedimentary sections in the Upper Dnieper region within an early medieval pre-urban center and in itsclose vicinities. Major phases of Subatlantic landscape evolution were defined as follows. A phase oflow and dispersed human impact (approximately 3,000 BP1,100 BP) is remarkable by widespreadzonal forest ecosystems and periodic slight increases of cultivated plants and others favored by culture.The phase included a stage of active floodplain sedimentation changed by a drier period (not earlierthan 2,400 BP) of no sedimentation and formation of Luvisols in the floodplain. The next phase ofintensive local human impact occurred during early medieval settlement (1,1001,000 BP) and is characterizedby extensive deforestation, wide introduction of variable human-related plants and deeptransformation of original soils within the settlements area: formation of Urbi-Anthropic Regosols. Aphase of no local human impact but generally higher anthropogenic pressure in the region (later than1,000 BP) started after a decline of the settlement. The number of settlements increased sharply inthe region in the 11th 13th centuries. This caused extensive anthropogenic deforestation and re-establishmentof human impact indicators after a slight forest invasion and sharp but short drop in humanrelatedplants. Floodplain sedimentation sharply increased. Garbi-Urbic materials of the settlementand Luvisols beyond the settlements borders were buried under floodplain alluvium about 1,000800 BP. At the end of this phase, formation of contemporary Fluvisols took place due to declining sedimentationrates (200150 BP). 2003 artículo científico 1026-8774 https://www.redalyc.org/articulo.oa?id=57220308 en http://www.redalyc.org/revista.oa?id=572 Revista Mexicana de Ciencias Geológicas application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Ciencias Geológicas (México) Num.3 Vol.20 |
