Investigation An area of land at Isebrook SEN College, Kettering (the site) is being considered for redevelopment by Northamptonshire County Council (the Client). The proposals for the site comprise the construction of a new two story building and associated external works for the College. Applied Geology was appointed by the Client to undertake a desk study/Phase I Environmental Risk Assessment and combined geotechnical and geoenvironmental investigation in order to: • assess the potential for hazardous substances or conditions to exist at the site that might warrant mitigation or remediation appropriate to the intended end use proposed by the Client. • establish geological conditions and geotechnical parameters to assist in the safe and economic engineering design of the proposed development. • Support a planning application. The terms of reference/brief for the works were specified by JPP Consulting on behalf of Lend Lease Consulting (Client’s Engineer) and are outlined in our proposal and estimate reference AG16-5227let001 dated 9th March 2016. The scope of works undertaken by Applied Geology comprised: • A site inspection and walkover survey • A review of the following desk study sources: GroundSure – GeoInsight & EnviroInsight environmental databases. GroundSure – MapInsight historical maps. British Geological Survey (BGS) - published information & on-line borehole database. Multi-Agency Geographical Information for the Countryside (MAGIC) on- line database. Environment Agency Web Site. • Ground investigation together with sampling, monitoring and a programme of laboratory testing. • Assessment and reporting of the results of the works. Underground service plans for the site were obtained by Applied Geology on 17th March 2016 and a utility survey drawing (with topographic survey information) dated November 2015 created by Subsight Survey Ltd was provided by the Client. 1.2 Report Layout This report presents a brief description of the site, the desk study data and the factual results of the intrusive investigations carried out. An interpretation of the ground conditions and a discussion/assessment of the findings is presented in the later report text sections. The main text of the report has been produced in a AG2437-16-Y63 APPLiED GEOLOGY Page 2 Isebrook SEN College, Kettering concise format, including the use of data tables to summarise key information where possible.

  • “Geochemical Characterisation of the Pliensbachian-Toarcian Boundary During the Onset of the Toarcian Oceanic Anoxic Event
    “Geochemical characterisation of the Pliensbachian-Toarcian boundary during the onset of the Toarcian Oceanic Anoxic Event. North Yorkshire, UK” Najm-Eddin Salem A thesis submitted to Newcastle University In partial fulfilment of the requirements for the degree of Doctor of Philosophy in the Faculty of Science and Agriculture School of Civil Engineering and Geosciences, Newcastle University, UK. February 2013 I ABSTRACT The lower Whitby Mudstone Formation of the Cleveland Basin in North Yorkshire (UK) is a world renowned location for the Early Toarcian (T-OAE). Detailed climate records of the event have been reported from this location that shed new light on the forcing and timing of climate perturbations and associated development of ocean anoxia. Despite this extensive previous work, few studies have explored the well-preserved sediments below the event that document different phases finally leading to large-scale (global) anoxia, which is the focus of this project. We resampled the underlying Grey Shale Member at cm-scale resolution and conducted a detailed multi-proxy geochemical approach to reconstruct the redox history prior to the Toarcian OAE. The lower Whitby Mudstone Formation, subdivided into the Grey Shale Member overlain by the Jet Rock (T-OAE), is a cyclic transgressive succession that evolved from the relatively shallow water sediments of the Cleveland Ironstone Formation. The Grey Shale Member is characterised by three distinct layers of organic rich shales (~10-60 cm thick), locally named as the ‘sulphur bands’. Directly above and below these conspicuous beds, the sediments represent more normal marine mudstones. Further upwards the sequence sediments become increasingly laminated and organic carbon rich (up to 14 wt %) representing a period of maximum flooding that culminated in the deposition of the Jet Rock (T-OAE).

  • Horizontal Fracture-Fault Network Characterization of Pavement Imagery of the Whitby Mudstone
    Horizontal fracture-fault network characterization of pavement imagery of the Whitby Mudstone Q.D. Boersma Department of Earth Sciences, Utrecht University, The Netherlands A Msc Thesis First Supervisor: Prof. dr. M.R. Drury (Utrecht University) Second Supervisor: dr. N.J. Hardebol (TU Delft) Third Supervisor: dr. M.E. Houben (Utrecht University) 1 Abstract Natural fractures play an important role in the hydrocarbon production from tight reservoirs. The need for fracture network pathways by fraccing matters particularly for shale gas prospects, due to their nano to micro darcies matrix permeabilities. The study of natural fractures from outcrops helps to better understand network connectivity and possibility of reactivating pre-existing planes of weakness, induced by hydraulic stimulation. Microseismicity also show that natural fractures are reactivated during fraccing in tight gas reservoirs and influence the success of the stimulation. An accurate understanding of natural fracture networks can help in predicting the development of fracture networks. In this research we analyze an outcrop analogue, the Whitby Mustone Formation (WMF), in terms of its horizontal fracture network. The WMF is the time equivalent of the Posidonia Shale Formation (PSF), which on itself is the main shale gas prospect in the Dutch subsurface. The fracture network of the WMF is characterized by a system of steep dipping joints with two dominant directions with N-S and E-W strike. The network was digitized from bird-view imagery of the pavement with a spatial extent of ~100 m at sub-cm resolution. The imagery is interpreted in terms of orientation and length distributions, intensity and fractal dimensions.

This study identifies how frequently equestrians use roads and what impacts their ability to do so. Over 6000 UK equestrians completed an online questionnaire about their exercise behaviours, road use and experiences of road-related incidents. Most equestrians use roads regularly. In the previous year, 68% of equestrians experienced a near- miss and 6% an injury-causing incident. Our results found that regional differences in road use and near-miss experiences coincided with off-road route availability. Road use was associated with the proximity of off-road routes, and road-using equestrians covered longer distances. Near-misses were associated with increasing frequency of weekly road use. Younger equestrians were more likely to use roads, but also to experience near-misses. Injury-causing incidents were associated with increasing road-use anxiety or ceasing to use roads (due to strong feelings of danger, compromised safety and conflict with other road users), the proximity of off-road routes, having a near-miss and Citation: Pollard, D.; Furtado, T.

  • Martin A. Whyte & Mike Romano. Dinosaur Footprints Associated With
    Dinosaur footprints associated with an ephemeral pool in the Middle Jurassic of Yorkshire, UK Martin A. Whyte & Mike Romano Sheffield Dinosaur Track Research Group, Department of Geography, University of Sheffield, Sheffield, S10 2TN, UK. ABSTRACT - A thin mudstone intercalation within channel sandstones of the Saltwick Formation (Middle Jurassic) of the Cleveland area of Yorkshire shows a succession of invertebrate traces followed by dinosaur tracks and then shrinkage cracks. The tridactyl prints, all made by the same type of small bipedal dinosaur, show an interesting range of morphologies, includ- ing imprints of the metatarsal area, consistent with their having been made in soft cohesive mud of varying moisture content. Some of the tracks indicate that the foot was moved backwards during withdrawal. Such foot movement can also be observed in modern emu locomotion. The pattern of shrinkage cracks is partly controlled by the prints. This sequence is comparable to the sequence of traces and structures which have been observed in a recent ephemeral pool and is interpreted as having formed in a similar environment. Uniquely for the Yorkshire area, the prints and cracks are infilled by small, now sideritised, pellets possibly of invertebrate faecal origin.
