| Zusammenfassung |
| 844 14C-dated coarse and fine-grained alluvial units have been classified using a range of criteria indicative of potential human impact. These include: changes in stratification, grain size and colour; inclusion of artefacts; and contaminant metal content. Pollen evidence where available was used to further classify alluvium related to deforestation or cultivation. Five alluvial unit groups are proposed that relate to: 1. deforestation; 2. cultivation; 3. metal mining; 4. engineering; and 5. other anthropogenic changes (that without pollen or contaminant metal content cannot be otherwise allocated). These data show distinctions in anthropogenic alluvia according to coarse and fine sedimentation, upland and lowland catchments, types and timings of human activity, and geographical location. We conclude using alluvial criteria that the ‘Anthropocene’, in the UK alone, was diachronous and specific to controlling factors such as the type of human activity and sedimentation context. |
