The Effects of Shrinkage and Swelling Were First Recognised by Geotechnical Specialists Following the Dry Summer of 1947
C:\Documents and Settings\adixon\Local Settings\Temporary Internet Files\Content.Outlook\7NFVY2G5\08-112 revised2.doc Modelling Volume Change Potential in the London Clay L. D. Jones & R. Terrington British Geological Survey, Keyworth, Nottingham. NG12 5GG UK (e-mail: [email protected]) Abstract The London Clay Formation is particularly susceptible to shrink–swell behaviour that has resulted in a long history of foundation damage due to ground movement across the outcrop. Damage has cost up to £500 million in a single year. Underlying most of the Greater London area, the London Clay Formation is of major engineering importance as it is on and within this formation that the majority of the city’s infrastructure, buildings and underground services are constructed. The Volume Change Potential of a soil is the relative change in volume to be expected with changes in soil moisture content and the subsequent shrinkage or swelling can cause major damage to structures above or below ground. Detailed statistical and spatial analyses of data across the London Clay outcrop has revealed a significant geographical trend in the volume change potential of this deposit, confirming an overall increase from west to east, but also showing subtle trends with depth. This paper describes how this analysis was carried out and shows how such assessments can yield valuable information about shrink–swell behaviour not only of the London Clay but of similar shrink– swell prone argillaceous formations elsewhere. Introduction The effects of shrinkage and swelling of clay soils, with respect to foundation and building damage, were first recognised by geotechnical specialists following the dry summer of 1947. -

Geology of the London Basin
Geology of the London Basin - 100 Million Years in the Making on 16 November 2018 Mr Philip Laurie first showed a geological map of London produced in 1848 by Stanford – the first of its kind. The Earth is 46,000 million years old, so much had happened before the London area made an appearance. The geological history of London started a hundred million years ago. For 60% of that time it has been under ice, causing sea levels to fall. He lives near the Ravensbourne, which rises south of the North Downs, runs through them and north to the Thames, emerging at Deptford Creek. How did it, and other rivers such as the Wandle, Darent and Medway, come to flow through the North Downs? At one time it was thought that there were faults in the chalk which gave them a way through, but this has been discounted. The Weald is now low lying, but when tectonic plate movement, mainly caused by Africa colliding with Europe, raised not only the Alps but buckled strata in northern Europe, a Wealden ridge was formed. An underlying chalk stratum buckled with high ridges at the South and North Downs and a dip under the Weald, squeezing up the soft sedimentary rocks between them to form the Ridge. Fast flowing streams from the ridge soon eroded channels in the chalk on their way to the sea. The ridge has since been eroding away (reducing river flows). They are ancient rivers. London is over a layer of cretaceous chalk about 40m down, which in turn is over gault clay. -
Wessex and the Reign of Edmund Ii Ironside
Chapter 16 Wessex and the Reign of Edmund ii Ironside David McDermott Edmund Ironside, the eldest surviving son of Æthelred ii (‘the Unready’), is an often overlooked political figure. This results primarily from the brevity of his reign, which lasted approximately seven months, from 23 April to 30 November 1016. It could also be said that Edmund’s legacy compares unfavourably with those of his forebears. Unlike other Anglo-Saxon Kings of England whose lon- ger reigns and periods of uninterrupted peace gave them opportunities to leg- islate, renovate the currency or reform the Church, Edmund’s brief rule was dominated by the need to quell initial domestic opposition to his rule, and prevent a determined foreign adversary seizing the throne. Edmund conduct- ed his kingship under demanding circumstances and for his resolute, indefati- gable and mostly successful resistance to Cnut, his career deserves to be dis- cussed and his successes acknowledged. Before discussing the importance of Wessex for Edmund Ironside, it is con- structive, at this stage, to clarify what is meant by ‘Wessex’. It is also fitting to use the definition of the region provided by Barbara Yorke. The core shires of Wessex may be reliably regarded as Devon, Somerset, Dorset, Wiltshire, Berk- shire and Hampshire (including the Isle of Wight).1 Following the victory of the West Saxon King Ecgbert at the battle of Ellendun (Wroughton, Wilts.) in 835, the borders of Wessex expanded, with the counties of Kent, Sussex, Surrey and Essex passing from Mercian to West Saxon control.2 Wessex was not the only region with which Edmund was associated, and nor was he the only king from the royal House of Wessex with connections to other regions. -
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. -
An Introduction to the Geology and Fossils of Essex
An Introduction to the Geology and Fossils of Essex The Foundations of Essex The rocks of Essex that were formed before the Ice Age are described as the 'solid' or 'bedrock' geology. Much of the solid geology is concealed beneath unconsolidated sediments laid down during the Ice Age. These Ice Age sediments (sand, gravel etc.) are called 'superficial' or 'drift' deposits. The Oldest Rocks The geological story of Essex starts with rocks that are between 440 and 360 million years old. Dating from the Silurian and Devonian periods these rocks consist of hard, slaty shales, mudstones and sandstones and are over 300 metres below the surface. These rocks have been encountered in boreholes at many places in Essex and they represent a time in the distant past when the first animals were leaving the sea to colonise the land. Similar rocks can be seen at the surface in the Welsh Borderland. Lying on top of these ancient rocks is the Gault, a marly clay from a muddy sea that dates from the middle of the Cretaceous period. This means that, beneath Essex, there is a gap in the geological record that represents about 250 million years and includes the Triassic, Jurassic and early Cretaceous periods. After deposition of the Gault, sand spread into this sea to form a deposit called the Upper Greensand. At this time sea levels were rising leading to widespread flooding of the continents, these are the conditions under which the next rock was formed - the Chalk. The Chalk Chalk is effectively the starting point of our geological story as it is the oldest rock exposed at the surface in our county. -
The Ice Age in North Hertfordshire
The Ice Age in North Hertfordshire What do we mean by ‘the Ice Age’? Thinking about ‘the Ice Age’ brings up images of tundra, mammoths, Neanderthals and great sheets of ice across the landscape. This simple picture is wrong in many ways. Firstly, there have been many different ‘Ice Ages’ in the history of the earth. The most dramatic happened between 2.4 and 2.1 billion years ago, known as the Huronian Glaciation. About the same time, earth’s atmosphere suddenly became rich in oxygen, and some scientists believe that the atmospheric changes reduced the temperature so much that the whole planet became covered in ice. 1: an Arctic ice sheet (© Youino Joe, USFWS, used under a Creative Commons licence) Another global cover of ice happened 650 million years ago when the first multi-celled animals were evolving. Geologists sometimes refer to this period as the ‘Snowball Earth’ and biologists know it as the Proterozoic. Temperatures were so low that the equator was as cold as present-day Antarctica. They began to rise again as concentrations of carbon dioxide in the atmosphere rose to about 13%, 350 times greater than today. Some carbon dioxide came from volcanic eruptions, but some was excreted by microbial life, which was beginning to diversify and increase in numbers. Neither of these Ice Ages is the one that dominates the popular imagination. Both happened many millions of years before life moved on to land. There were no humans, no mammals, no dinosaurs: none of the creatures familiar from The Flintstones. The period most people think about as the ‘real’ Ice Age is the geologists’ Pleistocene era, from more than two-and-a-half million years ago to the beginning of the Holocene, almost 12,000 years ago. -

Characteristics of movers 7. Area 8. International comparisons 9. Where can I find more information? 10. References 11. Background notes Page 2 of 16 1 . Main points There were an estimated 2.85 million residents moving between local authorities in England and Wales between July 2014 and June 2015. This is the same level shown in the previous 12-month period. There were 53,200 moves from England and Wales to Northern Ireland and Scotland, compared with 45,600 from Northern Ireland and Scotland to England and Wales. This means there was a net internal migration loss for England and Wales of 7,600 people. For the total number of internal migration moves the sex ratio is fairly neutral; in the year to June 2015, 1.4 million (48%) of moves were males and 1.5 million (52%) were females. Young adults were most likely to move, with the biggest single peak (those aged 19) reflecting moves to start higher education. -
Treasure Houses of Southern England
TREASURE HOUSES OF SOUTHERN ENGLAND BEHIND THE SCENES OF THE STATELY HOMES OF ENGLAND MAY 6TH - 15TH 2018 We are pleased to present the fi rst in a two-part series that delves into the tales and traditions of the English aristocracy in the 20th century. The English class system really exists nowhere else in the world, mainly because England has never had the kind of violent social revolution that has taken away the ownership of the land from the families that have ruled it since medieval times. Vast areas of the country are still owned by families that can trace their heritage back to the Norman knights who accompanied William the Conqueror. Here is our invitation to discover how this system has come about and to experience the fabulous legacy that it has BLENHEIM PALACE bequeathed to the nation. We have included a fascinating array of visits, to houses both great and small, private and public, spanning the centuries from the Norman invasion to the Victorian era. This spring, join Discover Europe, and like-minded friends, for a look behind the scenes of TREASURE HOUSES OF SOUTHERN ENGLAND. (Note: Part II, The Treasure Houses of Northern England is scheduled to run in September.)
