  • A CRITICAL EVALUATION of the LOWER-MIDDLE PALAEOLITHIC ARCHAEOLOGICAL RECORD of the CHALK UPLANDS of NORTHWEST EUROPE Lesley
    A CRITICAL EVALUATION OF THE LOWER-MIDDLE PALAEOLITHIC ARCHAEOLOGICAL RECORD OF THE CHALK UPLANDS OF NORTHWEST EUROPE The Chilterns, Pegsdon, Bedfordshire (photograph L. Blundell) Lesley Blundell UCL Thesis submitted for the degree of PhD September 2019 2 I, Lesley Blundell, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. Signed: 3 4 Abstract Our understanding of early human behaviour has always been and continues to be predicated on an archaeological record unevenly distributed in space and time. More than 80% of British Lower-Middle Palaeolithic findspots were discovered during the late 19th/early 20th centuries, the majority from lowland fluvial contexts. Within the British planning process and some academic research, the resultant findspot distributions are taken at face value, with insufficient consideration of possible bias resulting from variables operating on their creation. This leads to areas of landscape outside the river valleys being considered to have only limited archaeological potential. This thesis was conceived as an attempt to analyse the findspot data of the Lower-Middle Palaeolithic record of the Chalk uplands of southeast Britain and northern France within a framework complex enough to allow bias in the formation of findspot distribution patterns and artefact preservation/discovery opportunities to be identified and scrutinised more closely. Taking a dynamic, landscape = record approach, this research explores the potential influence of geomorphology, 19th/early 20th century industrialisation and antiquarian collecting on the creation of the Lower- Middle Palaeolithic record through the opportunities created for artefact preservation and release.

  • Chapter 2 Physical Characteristics of the Study Area
    CHAPTER 2 PHYSICAL CHARACTERISTICS OF THE STUDY AREA 2.1. Location of study area The study area incorporates part of north Hertfordshire, south and mid- Bedfordshire as well as the southwest corner of Cambridgeshire and lies approximately 40 km north of London (Figure 1.1). Coverage of the area by British Geological Survey (BGS) 1:50,000 map sheets is shown in Figure 2.1. 2.2. Bedrock geology The strikes of the solid geological formations are approximately northeast- southwest across the study area (Figure 2.2). The solid geological succession is shown in Table 2.1. To the northwest of the Chiltern Hills the Gault Clay forms a rich agricultural landscape, representing a continuation of the Vale of Aylesbury. Beyond this, running approximately from Bow Brickhill (SP915343) to Gamlingay (TL234525) is a discontinuous ridge formed by the Woburn Sands Formation, part of the Lower Greensand. This prominent ‘Greensand Ridge’, rising to 170 m O.D. at Bow Brickhill, separates the Cretaceous clays from the Jurassic Oxford and Ampthill Clays to the northwest. The oldest formation is recorded in a borehole (TL23NE1) at Ashwell (TL286390), where Devonian strata were reached at a depth of 186.54 m, i.e. 93 m below O.D. (Smith, 1992). Lying just beyond the northern boundary of the present study area, north of the River Ouse, a borehole (TL15NE2) at Wyboston (TL175572) penetrated Ordovician rocks of Tremadoc age at a depth of approximately 230 m (Moorlock et al ., 2003). The Oxford Clay of the Upper Jurassic represents the oldest formation outcropping within the study area.
