The Layers of Archaeology
Soil Layers
O horizon - The top layer of soil is made up mostly of leaves and decomposed organic matter.
A horizon (topsoil) - Plants grow in this dark-coloured layer, which is made up of decomposed organic matter mixed with mineral particles.
E horizon - This eluviation (leaching) layer has a light colour and is made up of sand and silt. We often find significant archaeological artefacts in this layer.
B horizon (subsoil) - Contains clay and mineral deposits that it receives from layers above, when water drips through.
C horizon - Regolith consists of slightly broken up bedrock. Plant roots do not penetrate into this layer.
R horizon - The bedrock layer that is beneath all the other layers.Gallery
