Analysis of brown earth palaeosols and derived sediments associated with a Mesolithic pit and two Early Bronze Age burnt mounds on Exmoor, UK.

: The deforestation of upland areas in southwest Britain during the mid-Holocene has become an archaeological narrative, derived from the analysis of pollen within the upland peat deposits. The transition of these environments from brown earth soils supporting temperate deciduous woodland, into the now familiar podzolic peat mire landscapes is seemingly associated with abandonment of the uplands in late prehistory. The prehistoric archaeological records of these landscapes are rich and significant questions remain unanswered about prehistoric societies and their role in the environmental transition of these upland systems. Despite these rich archaeological records and detailed palaeoecological studies, the geoarchaeological study of the pre-peat sediments has remained somewhat limited. This paper provides the analysis of a Mesolithic heated pit infilled with a brown earth soil, and the pre-monument deposit sequences at two Early Bronze Age burnt mounds. The analysis of these dated sequences provides an increased understanding of these environments prior to the transition of these areas into stagnogley podzols and identifies considerable human impacts, indicating human activities were important in stressing soils in these environments and contributing to their degradation.
