Teindland Palaeosol Formation

Computer Code: TELND Preferred Map Code: notEntered
Status Code: Full
Age range: Ipswichian Stage (QI) — Ipswichian Stage (QI)
Lithological Description: The Teindland Palaeosol Formation is developed on the surface of the Orbliston Sand Bed and is podzolic in character. It comprises a thin redeposited humic 'H' horizon, a bleached 'Ea'horizon up to 15cm thick, an intermittently developed iron pan and a lower 'strong brown' (7.5 YR 5/8) 'Bs' horizon, 5 to 15cm thick. Overlying the humic horizon are thin layers of organic sand with charcoal fragments. At Teindland Quarry, the Badentinan Sand Bed, up to 1.5m thick, overlies these organic sands. The lower 80-100cm comprises parallel thin beds of brown polleniferous sand. This pollen was partly derived from reworking of soils around the site and partly from contemporaneous sparse grassland. The upper 50-70cm of the sand is non-polleniferous. The presence of small gravel clusters, silt balls, an isoclinical fold and of shear zones suggest a glacial or glacitectonic influence on, or more likely following, deposition in a small pond. The Teindland Palaeosol Formation is less well developed at Red Burn, where the parent material is a greenish grey (5 GY 6/1) sandy diamicton and where the overlying organic sediments are thin and disturbed by cryoturbation. Pollen analysis of the Teindland Palaeosol Formation and the overlying organic sands shows that the earliest vegetation recorded at the site was woodland of 'interglacial' character with grassland openings. Pine and alder are represented at Teindland, and alder and hazel at Red Burn. Podzolisation of the palaeosol ended with an influx of sands derived from erosion of the surrounding slopes, perhaps in response to burning during a grassland phase.The combined evidence of environmental deterioration from pollen and sediments suggests events characteristic of the end of an interglacial episode. Luminescence dates of 79 and 67 ka for the sands overlying the soil suggest that the soil developed towards the close of Oxygen Isotope Stage OIS 5e (Ipswichian).
Definition of Lower Boundary: At Teindland Quarry, the Teindland Palaeosol Formation rests unconformably on up to 3m of very pale brown (10 YR 7/4) sand (Orbliston Sand Bed of the Deanshillock Gravel Formation). At the Red Burn site, the Teindland Palaeosol Formation rests unconformably on a unit of sand with sporadic clasts that appears to correlate with the Deanshillock Gravel Formation at the base of the known sequence at Teindland Quarry.
Definition of Upper Boundary: At Teindland Quarry the organic sediments of the Teindland Palaeosol Formation are overlain by up to 2.2m of bedded sandy diamicton, the Woodside Diamicton Formation with crude parallel bedding and localised wash horizons.
