Report: Ribble Valley - waterlogged plant macrofossil; the materials are organic detritus from the base of a sequence of coarse to medium sand flood laminations. The sequence of flood laminations was sampled from a core located in the centre of a palaeochannel with surface expression from lower Ribble terrace 3. The organic materials were incorporated within a basal flood lamination just overlying channel gravels. The materials are detrital rather than in situ, but they comprise soft plant matter, probably locally derived and likely to be similar in age to the flood deposit.

Report: Burlescombe - waterlogged plant macrofossil; this sample is from context 691. It represents the waterlogged fill of the plank-lined springhead (678). This was excavated in two spits. Due to the depth of deposits of overlying colluvium there is no chance of intrusive material or residuality. The feature was cut into natural sands and gravels, immediately above the water table. The context was undisturbed and unbioturbated. The pH is likely to be slightly alkaline (approximately pH 6.5) although exact parameters are unknown.

Report: Suffolk Rivers - waterlogged plant macrofossil; Poaceae fragments; .73m OD; this sample was taken from the base of a light grey-brown organic sand unit, which is underlain by dark brown well humified peat. The underlying geology of the area surrounding Mickle Mere comprises predominantly of chalk, chalk till, and glaciofluvial drift and till. The stratigraphy and sedimentology of the deposits suggest the area initially infilled naturally through biogenic in situ sedimentation. Thin minerogenic horizons are present within the peat deposits, which may have been accumulated during periods of temporary catchment instability and floodplain flodding. The peat is capped by a layer of silt which is likely to have accumulated through floodplain deposition. The natural water table was located c 0.4m from the surface. Rootlet penetration was not evident within the core upon extraction.

Report: Gwithian - carbonised residue; internal, Gwithian-style base sherd; the stratigraphy for GMI was recorded as three broad sandy-soil occupation layers (A, B, C) each probably separated by layers of blown sand. Within each layer were features such as huts and pits. Layer C represents the lowest of the three occupation layers: the sample comes from within a building within the layer context (2210). The geology consists of slate bedrock beneath blown calcareous sand layers. Layer C is the lowest occupation layer, between two sand layers.

Report: Gwithian - carbonised residue; internal, undecorated body sherd; the stratigraphy for GMI was recorded as three broad sandy-soil occupation layers (A, B, C) each probably separated by blown sand. Within each layer were features such as huts and pits. Layer C represents the lowest of the three occupation layers. This sample was recorded as 'mid house 1' within layer C: context (2210). The geology consists of slate bedrock beneath blown calcareous sand layers. Layer C is the lowest occupation layer, between two sand layers.

Report: Trent Valley Survey: Barton in Fabis North- Plant macrofossil; from an organic-rich core taken from a meander loop palaeochannel located on the Holocene floodplain of the River Trent (second terrace). The palaeochannel is incised into a Holocene terrace, which comprises basal sands and gravels overlain by fine grained sediments. This sample was collected from the upper part of an organic horizon of a palaeochannel at a depth of between 1.55-1.75m. Local geology comprises Permo-Triassic sandstones. No root penetration or contamination of the core was observed.

Report: Ribble Valley - waterlogged plant macrofossil; unidentified buds and twigs; the material is from a flood horizon towards the top of the flood sequence of T2 C4. The sequence of flood laminations was sampled from a core sequence located in the centre of a palaeochannel with surface expression from lower Ribble terrace 3. The organic materials were incorporated within the uppermost sand flood lamination 1.5-1.45m below the switch to silt and clay laminations. The organic materials are flood trash organic materials, and are likely to be similar in age to the surrounding flood deposit. The deposit overlies channel gravels and is buried by a further 0.75m of flood laminated sands, silts, and clays. There is no evidence for bioturbation or downwards root penetration, because the flood laminations are undisturbed. At the time of sampling the water table was at 0.5m beneath the surface, and based on iron and manganese discolouration probably oscillates around 0.5-0.75m below the surface.

Report: Burlescombe - waterlogged plant macrofossil; Rumex obtusifolius, 10 seeds; the sample is from context 691; it represents the fill of the plank-lined springhead. The deposit surviving within the well-head was 100mm thick and was sampled in two spits. Waterlogged material from both spits has been identified as suitable for carbon dating. Due to the depth of deposits overlying colluvium there is no chance of intrusive material or residuality. The feature was cut into natural sands and gravels. The local geology is gravel. The context was immediately above the water table and was undisturbed and unbioturbated. The pH is likely to be slightly alkaline (approximately pH 6.5) although exact parameters are unknown.

Report: Bestwall Quarry- Charcoal; from a circular pit. The upper layer (160) was packed with charcoal lumps, however there was also a lower layer consisting of ashy sand and smaller charcoal pieces. No evidence of intrusion or residuality was observed, and no pottery was recovered. The local geology is valley gravels overlain by sandy acidic subsoils and topsoils. The feature was cut into subsoil and was approximately 0.40m below the ground surface. There was no disturbance or waterlogging.

Report: Bone, id as human, 13156, from cemetery at Castle Mall, Norwich, Norfolk, England. Subm E Shepherd. Comment (subm): Burial OxA-6382 has a Middle Saxon date. Samples OxA-6370 to -6385 and -6881 all came from the northern part of the cemetery of St John de Berstrete (later St John the Baptist, Timberhill), documented from AD 1157. This cemetery, containing a high proportion of leper burials, had been dated on ceramic and other evidence to late 12th to 14th century. These determinations in the pre-Conquest period conflict with the present local ceramic sequence. [further comment in ref.]

Report: Ribble Valley - waterlogged plant macrofossil; leaf fragments; peat sampled from cut exposures in the banks of the Calder near Whalley. In the bank section the peat profile targeted a 0.26m thick peat that overlies bar-form gravels. This sample is taken from the base (00-40mm) of this 0.26m thick peat sequence, overlying coarse river gravels, which in turn are buried by a sequence of flood silts and clays. The peat has formed over the bar gravels, probably encouraged by the saturated conditions, and is composed of in situ plant remains, and so the organic materials are in situ rather than detrital. The peat deposit overlies fluvial gravels and is buried by a further 1m of flood-laminated silts and clays. Downwards root penetration is possible within woody peat deposits of this nature, as is the migration of different organic fractions, particularly fulvic acid.

Report: Ribble Valley - waterlogged wood; unidentified roundwood fragments; the sample is organic detritus from within a sequence of flood-laminated silts and clays. The sequence of flood laminations was sampled from a core located in the centre of a palaeochannel with surface expression from Hodder terrace 3 core 3/2. The organic materials were incorporated within the uppermost sequence of fine-grained flood laminations and overlay 1m of peat deposits. The materials are detrital rather than in situ, but they comprise soft plant matter, probably locally derived and are likely to be similar in age to the flood deposit. There is no evidence for bioturbation or downwards root penetration, because the flood laminations are undisturbed. At the time of sampling the water table was at 0.25m beneath the surface, and based on iron and manganese discolouration probably oscillates around 0.25-0.5m below the surface.

Report: The Rye area project: RYE4, West Winchelsea- Peat; bulk; the sample comes from a 4cm slice of peat (-1.99- -2.03m OD). The local solid geology is the (non-calcareous) Hastings Bed Group (sandstones, siltstones, and clays). These are covered by several metres of Holocene drift deposits (marine alluvium and peat). The samples are recovered from several metres below the level of the local watertable. Pollen analysis of Sediment across the span of the sample WINCH1 indicate a rich-sedge fen community transitional between alder/willow carr and saltmarsh vegetation.

Report: Shell, D9, from Six Cairns, Banks Head, South Ronaldsay, Orkney Islands, off Scotland. Subm A C Renfrew 1987. Comment (subm): date series indicates two phases of activity, around beginning of 1st millennium AD and around AD 1000; but there are no artefacts to relate to these dates. Comment (lab): correction for marine reservoir effect is necessary if the two shell dates hence are to be directly compared with the dates on bone; this correction is in the order of 405 40 years giving a reservoir-adjusted age of 955 70 for this date.

The trunk was overlain by a thick bank of colluvium, and was set into natural sands with an area of waterlogged trampling around it. There is little or no chance of intrusive elements or residuality. The local geology is gravel. The spread of material immediately overlies the water table (the interface of this context and the underlying ones representing the level of the water table). The context was undisturbed and unbioturbated. The pH is likely to be slightly alkaline (approximately pH 6.5) although exact parameters are unknown.

Report: Bestwall Quarry- Charcoal; from a subrectangular pit with a 0.10m basal deposit of charcoal. The upper fill was sandy loam with dispersed pieces of Charcoal. There was burnt sand on the base of the pit. No evidence of intrusion or residuality was observed. Five sherds of late Iron Age pottery were found in the fill. The local geology is valley gravels overlain by sandy acidic subsoils and topsoils. The feature was cut into subsoil and was approximately 0.40m below the ground surface. There was no disturbance or waterlogging.

Report: Ribble Valley - waterlogged plant macrofossil; leaf fragments; the Calder Bank peat section was sampled from cut exposures in the banks of the Calder near Whalley. This profile targeted a 0.26m thick peat that overlies bar-form gravels. This sample is taken from the top (0.24-0.26m) of this 0.26m thick peat sequence, overlying coarse river gravels, which in turn are buried by a sequence of flood silts and clays. The peat has formed over the bar gravels, probably encouraged by the saturated conditions, and is composed of in situ plant remains and so the organic materials are in situ rather than detrital. Downwards root penetration is possible within woody peat deposits of this nature, as is the migration of different organic fractions, particularly fulvic acid.

Report: Lynford Quarry, Mundford- Sediment; bulk; three monoliths of sediment were collected for pollen analysis from upper deposits of the south-facing section. Contexts 20319 (dark brown organic silty clay) and 20317 (grey organic sand) were sampled. The lowest monolith (segment 0.94-1.03m, c 2.04m below the surface) was subsampled by the sedimentologist for radiocarbon dating. The deposits sampled for pollen included a succession of Holocene channels and sediments. The earliest features sampled were braided channels filled with grey to dark brown organic sand, with lower beds of medium to coarse gravels (sample 30085 was taken from context 20317 within this group). Next in the sequence was a series of east-to-west migrating channels. These had basal layers of coarse gravel, and fills of interbedded dark grey organic sand and coarse gravel, coarse gravel with clasts of redeposited organic material, grey to brown medium sand with lenses of brown organic sand, and moderately-sorted coarse gravel and dark brown organic sand. The last feature in this sequence was a north-south channel, filled by dark grey organic sand with rare flint gravel. The sequence was capped by topsoil, composed of brown sand and organic matter and disturbed deposits of grey to dark brown sand and organic material redeposited by quarrying activity. The sample was likely to have been at or just below the watertable prior to drainage (12-18 months before the excavation).

Report: The Rye area project: RYE4, West Winchelsea- Peat; bulk, -1.99 - - 2.03m OD; the sample comes from a 4cm slice of peat (-1.99- -2.03m OD). The local solid geology is the (non-calcareous) Hastings Bed Group (sandstones, siltstones, and clays). These are covered by several metres of Holocene drift deposits (marine alluvium and peat). The samples are recovered from several metres below the level of the local watertable. Pollen analysis of Sediment across the span of the sample WINCH1 indicate a rich-sedge fen community transitional between alder/willow carr and saltmarsh vegetation.

Report: Burlescombe - waterlogged plant macrofossil; Rubus sect. Glandulosus, 20 seeds; this sample is from context 697; it represents the waterlogged 'trample' around the hollow tree trunk, dark reddish brown (5YR 3/3) gritty sand. Due to the depth of the overlying colluvium there is no chance of intrusive material or residuality. The local geology is gravel. The context was immediately above the water table.The context was undisturbed and unbioturbated. The pH is likely to be slightly alkaline (approximately pH 6.5) although exact parameters are unknown.

Report: Burlescombe - waterlogged plant macrofossil; Polygonum hydropiper, 20 seeds ; this sample is from context 700. The context represents the fill of a hollowed out tree trunk (willow or poplar). The waterlogged fill was taken out in spits, the first and last spits (spits 0 and 9) both had suitable waterlogged plant macrosfopssils and have been submitted for dating. The trunk was overlain by a thick band of colluvium, and was set into natural sands with an area of waterlogged trampling around it. There is little or no chance of intrusive elements or residuality. The local geology is gravel. The context was undisturbed and unbioturbated. The pH is likely to be slightly alkaline (approximately pH 6.5) although exact parameters are unknown. The base of the hollow trunk was below the water table.

Report: Bone from top burning level (sample SP21) at Iona Old Guest House, Strathclyde, Scotland. Coll R Reece 1974. Subm R Reece 1975. Comments (lab): Result has large uncertainty because of insufficient sample material, which required toping-up with 14C-dead CO2 after collagen extraction and combustion; (subm): This and HAR-1276, 1241 correlate with historical evidence for Viking raids on Iona.

Report: Bestwall Quarry- Charcoal; from a subrectangular pit with a 0.10m basal deposit of Charcoal. The upper fill was sandy loam with dispersed pieces of Charcoal. There was burnt sand on the base of the pit. No evidence of intrusion or residuality was observed. Five sherds of late Iron Age pottery were found in the fill. The local geology is valley gravels overlain by sandy acidic subsoils and topsoils. The feature was cut into subsoil and was approximately 0.40m below the ground surface. There was no disturbance or waterlogging.

Report: Ribble Valley - waterlogged wood; unidentified roundwood fragments; the materials are organic detritus from within a sequence of flood-laminated silts and clays. The sequence of flood-laminations was sampled from a core located in the centre of a palaeochannel with surface expression from Hodder terrace 3 core 3/2. The organic materials were incorporated within the uppermost sequence of fine-grained flood-laminations and overly 1m of peat deposits. The materials are detrital rather than in situ, but they comprise soft plant matter, probably locally derived and are likely to be similar in age to the flood deposit. The deposit overlies channel gravels and is buried by 0.75m of flood-laminated silts and clays, and surface soil. There is no evidence for bioturbation or downwards root penetration, because the flood laminations are undisturbed. At the time of sampling the water table was at 0.25m beneath the surface, and based on iron and manganese discolouration probably oscillates around 0.25-0.5m below the surface. Organic flood trash of this type, where the character of plant remains (cell and tissue structure) is still discernible, is unlikely to predate the flood by more than 10-20 years.
