Carbon Date. 500BC. Middle Iron Age Carbon Dates

Report: The Rye area project: Houghton Green- Peat; .17 - 2.21m OD; the sample was taken from the top of a unit of black well-humified silty peat (B), immediately below a layer of grey-brown marine/intertidal clay (A).The solid geology of the area around Houghton Green is the Hastings Bed Group (mainly sandstones, siltstones, and clays). The watertable at the site is within 1m of the modern ground surface. The depth from which the sample is taken should prove sufficient to minimise possible contamination by modern rootlet penetration. Pollen assemblages from Houghton Green contain 'super abundant' percentages of Alnus glutinosa pollen, indicating the presence of dense alder carr vegetation around the site at the time of peat accumulation. A transitional (non-erosive) A/B contact is indicated.

Report: Bestwall Quarry 2004-7 - waterlogged plant macrofossil; -0.87 - -0.97m OD; the sample comes from a depth of 0.90-1m measured from the surface of the peat deposit. There was no intrusion or residuality. The local geology is valley gravels overlain by sandy acidic topsoils and subsoils. The waterlogged peat deposit was contained within the gravel horizon. Eighteenth- to nineteenth-century ceramic and stone land drains had been laid on top of the peat deposit. The sample was permanently waterlogged. Approximately 0.50m of topsoil had been removed.

Report: Charred plant remains, 214, from lowest 350mm of primary fill of enclosure ditch at Park Farm, Barford, Warwickshire, England. Subm S Cracknell. Comment (subm): samples covered a range of features originally thought to be of a single period; however, this second (Glasgow lab) series (GU-5043 to -5045) confirmed an Iron Age date for the enclosure. OxA-2305 and -2306 appear to represent earlier temporary use of the site.

Report: The Rye area project: Pewis Marsh (Pewis 2)- Sediment; -0.94 - -0.99m OD; PEWIS 2.1 is taken from the base of a 'buried soil' horizon (unit B), immediately above a contact onto black Woody peat (unit C). The solid geology of the area around Pewis Marsh is the Hastings Bed Group (mainly sandstones, siltstones, and clays). The watertable at the site is within 1m of the modern ground surface. The depth from which the sample is taken precludes the possibility of contamination by modern rootlet penetration or disturbance. Pollen assemblages from unit B contain significant frequencies of pollen from grasses (Poaceae) and bog taxa (eg Myrica, Calluna) together with spores of Sphagnum. These indicate relatively open, oligotrophic conditions at the time of Sediment deposition.

Report: The Rye area project: Cadborough Cliff- Peat; humin, -1 - -1.04m OD; the sample was taken from the top of a unit of dark brown Woody peat (B), immediately below a contact with marine/intertidal silty clays (A). The solid geology of the area around Cadborough Cliff is the Hastings Bed Group (mainly sandstones, siltstones, and clays). The watertable at the site is within 1m of the modern ground surface. The depth from which the sample is taken precludes any possibility of contamination by modern rootlet penetration. Pollen assemblages from the top of the peat indicate fen carr vegetation was locally dominant at the time of peat accumulation. Rising percentages of Myrica gale pollen suggest the environment was becoming increasingly acidic and nutrient poor. A transitional (non-erosive) contact between units A/B is indicated.

Report: Ribble Valley - waterlogged wood; unidentified roundwood, single fragment; the material is from a sandy flood layer towards the base of a sequence of a 4.2m thick flood laminated palaeochannel fill. The core was taken from the centre of a palaeochannel with surface expression from lower Ribble terrace 4. The wood remains were incorporated within thick basal sandy gravel flood laminations 0.25m above the underlying channel gravels. The materials are detrital rather than in situ, but they comprise wood remains, 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 0.5-0.75m below the surface.

Report: Trent Valley Survey: Seymour Drain- Plant macrofossils; from an organic-rich core taken from a sinuous palaeochannel located on the Holocene floodplain of the River Trent (first terrace). The palaeochannel is incised into a early Holocene terrace, which comprises basal sands and gravels overlain by fine-grained sediments. This sample was collected from the upper part of a brown silty peat at a depth of between 0.3-0.5m. Local geology comprises Permo-Triassic sandstones. No root penetration or contamination of the core was observed.

Report: Hartshill Copse- Charcoal; sample recovered from northeastern half of the single fill of this feature 4021, one of the outer ring of postholes forming Roundhouse B. There was no physical relationship with other features. The context was sealed by topsoil, ploughed for at least the last 15 years. The topsoil was stripped prior to excavation and left exposed for two years. Resultant weed growth was cleared by mechanical removal of uppermost gravel surface, immediately prior to excavation. Underlying geology is acidic flint gravel, free-draining and fine-fractioned.

Report: Ribble Valley - waterlogged plant macrofossil; unidentified wood, and monocot stem and roots; the material is organic detritus from the uppermost of a sequence of coarse to medium sand flood laminations within the back palaeochannel on terrace 3. The core was taken from the centre of a palaeochannel. The organic materials were incorporated within the uppermost sandy flood lamination below the switch to silt and clay laminations. The materials are detrital rather than in situ. They are 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 0.5m beneath the surface and, based on iron and manganese discolouration, probably oscillates around 0.5-0.75m below the surface. Organic flood trash of this type is unlikely to predate the flood by more than 10-20 years.

Report: Hartshill Copse- Charcoal; the sample was recovered from the northeastern half of the single fill of this feature 4021, one of the outer rings of postholes forming Roundhouse B. There was no physical relationship with other features. The context was sealed by topsoil, ploughed for at least the last 15 years. The topsoil was stripped prior to excavation and left exposed for two years. Resultant weed growth was cleared by mechanical removal of uppermost gravel surface, immediately prior to excavation. Underlying geology is acidic flint gravel, free-draining and fine-fractioned.

Report: Burlescombe - charcoal; from a monolith taken through a series of colluvial deposits across most of the features on site. Due to the depth of deposits overlying this material there is no chance of intrusive material or residuality. The local geology is gravel. The spread of material 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: Burlescombe - waterlogged wood; unidentified twig; this sample is from context 682. This context represents the waterlogged fill of a pit (672) with unknown function, sealed by a layer of oxidized gravel ('burnt mound'). 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: Hartshill Copse- Charcoal; the sample was recovered from the northeastern half of the single fill of this feature 4021, one of the outer rings of postholes forming Roundhouse B. There was no physical relationship with other features. The context was sealed by topsoil, ploughed for at least the last 15 years. The topsoil was stripped prior to excavation and left exposed for two years. Resultant weed growth was cleared by mechanical removal of uppermost gravel surface, immediately prior to excavation. Underlying geology is acidic flint gravel, free-draining and fine-fractioned.

Report: Wood, AML 878289, B28/190, from estuarine clays on foreshore at Goldhanger, Site 28, Essex, England. Subm PM 1987. Comment (subm): samples exposed by tidal erosion were first located in 1985. Dating through stratigraphy is impossible, and no artefacts were found. Late prehistoric date was suggested by elevation and analogy with other 14C dates, but results indicate multi-component site of greater complexity than originally thought.

Report: Swale-Ure Washlands: F45, Nosterfield- Wood; a Russian core and monolith tins were used to sample organic from a collapsed feature labelled 'F45' at the Nosterfield sand and gravel quarry. The pit from which the samples were taken has since been stripped by the gravel company. The pits or collapsed features are interpreted as 'probably natural features within the already forming fluvioglacial gravels bordering the River Ure' (Tipping 2000). The section occurs in a gravel quarry, where it was exposed temporarily during quarry excavation. The collapse features probably formed in the gravels as a result of cavern collapse in the underlying limestone. The collapse features would then quickly fill up with Sediment.

Report: Wood, AML 8650294, B28126, from structure formerly sealed beneath estuarine sediments on foreshore at Goldhanger, Site 28, Essex, England. Subm PM 1986. Comment (subm): samples exposed by tidal erosion were first located in 1985. Dating through stratigraphy is impossible, and no artefacts were found. Late prehistoric date was suggested by elevation and analogy with other 14C dates, but results indicate multi-component site of greater complexity than originally thought.

Report: Swale-Ure Washlands: F45, Nosterfield- Wood; a Russian core and monolith tins were used to sample organic from a collapsed feature labelled 'F45' at the Nosterfield sand and gravel quarry. The pit from which the samples were taken has since been stripped by the gravel company. The pits or collapsed features are interpreted as 'probably natural features within the already forming fluvioglacial gravels bordering the River Ure' (Tipping 2000). The section occurs in a gravel quarry, where it was exposed temporarily during quarry excavation. The collapse features probably formed in the gravels as a result of cavern collapse in the underlying limestone. The collapse features would then quickly fill up with Sediment.

Report: Hartshill Copse- Charcoal; the sample was recovered from the southern half of single fill of feature 299, a posthole cutting pit/posthole 297, which appears to form part of porch of Roundhouse B. 297 is cut to the north-east by a further posthole 1674, which is similar to 299. These later features may or may not be associated with Structure B. Context sealed by topsoil, ploughed for at least the last 15 years. The topsoil was stripped prior to excavation and left exposed for two years. Resultant weed growth was cleared by mechanical removal of uppermost gravel surface, immediately prior to excavation. Underlying geology is acidic flint gravel, free-draining, and fine-fractioned.

Report: Bone, id as ox, NMW 44.32.Z.2, from Llyn Cerrig Bach, Anglesey, Gwynedd, Wales. Subm W H Manning. Comment (subm): dates suggest that, in addition to the well-known metalwork deposits, there was a rite of animal sacrifice here which continued from at least 4th to 2nd century BC cal, and possibly later (OxA-6390). The metalwork is usually assigned to 1st century BC/1st century AD; this raises the question of whether some of the metalwork can be dated earlier (not impossible), or the metalwork deposition was a later development of an earlier custom of animal sacrifice.

Report: Wood, AML 8650297, B28129, from structure formerly sealed beneath estuarine sediments on foreshore at Goldhanger, Site 28, Essex, England. Subm PM 1986. Comment (subm): samples exposed by tidal erosion were first located in 1985. Dating through stratigraphy is impossible, and no artefacts were found. Late prehistoric date was suggested by elevation and analogy with other 14C dates, but results indicate multi-component site of greater complexity than originally thought.

Report: Hartshill Copse- Carbonised residue; adhering to internal surface of pot sherd; sample recovered from final fill of clay-lined pit, 423. This fill sealed a carbon-rich deposit, and probably represents silting/natural infilling subsequent to disuse. No physical relationships with other features, but located within southwestern corner of ditched enclosure. Context sealed by topsoil, ploughed for at least the last 15 years. Topsoil was stripped prior to excavation and left exposed for two years. Resultant weed growth was cleared by mechanical removal of uppermost gravel surface, immediately prior to excavation. Underlying geology is acidic flint gravel, free-draining, and fine-fractioned.

Report: Latton Lands - charcoal; the sample was recovered from pit 3869 and comprised an upper fill in a largely silted-up pit containing a dump of burnt material. This fill also contained a neonate skeleton and metal finds as well as metalworking debris, burnt stone, middle Iron Age pot, and bone. There is some possibility of intrusion. Rootlet penetration and the position of the watertable are not known, but the sample did not contain much rooty material and the deposit did not appear to have been waterlogged. Snail shells were well preserved, indicating a calcareous sediment.

Report: Hartshill Copse- Grain; the sample was recovered from the northern half of single fill of the feature, one of inner ring of postholes forming Roundhouse B. No physical relationships with further features. The underlying geology is an acidic flint gravel, free-draining and fine-fractioned. The archaeological features are cut into the upper surface of the gravel and were covered by a ploughsoil up to 0.5m thick. The site was under arable cultivation for at least the last fifteen years. Prior to excavation the ploughsoil had been stripped and the site left exposed for 23 months, resulting in weed growth over the exposed surface. The weeds were cleared by mechanical removal of the uppermost gravel surface immediately prior to excavation.
