Geological Conservation Strategy for Hertfordshire A Geological Conservation Strategy for Hertfordshire Hertfordshire RIGS Group 2003 Great Britain is the cradle of the science of geology. It was here that many of the periods of geological time were first defined and named. Countless eminent geologists, professional and amateur, have sharpened their eyes and scientific minds on Britain’s earth science sites. Yet these sites, which display the visible evidence of the Earth’s formation and transformation through rocks, fossils and landforms, have been disappearing at an accelerating rate in the face of the many pressures imposed by our modern way of life.

  • Consultation Statement for the Sele Neighbourhood Area Plan
    CONSULTATION STATEMENT FOR THE SELE NEIGHBOURHOOD AREA PLAN INTRODUCTION 1. This Statement has been prepared to append the Draft version of the Sele Neighbourhood Area Plan (“The Plan”) for submission to the relevant local planning authority, East Herts District Council under the Neighbourhood Planning Regulations 2012 (“The Regulations”). 2. A consultation statement is a statutory document of the Neighbourhood Planning process. The Regulations of 2012, Part 5 Paragraph 15 (2) define a “consultation statement” as a document that: a) Details of the persons and bodies who were consulted about the proposed neighbourhood development plan; b) Explains how they were consulted; c) Summarises the main issues and concerns raised by the persons consulted; d) Describes how these issues and concerns have been considered and, where relevant, addressed in the Neighbourhood Development Plan. 3. The consultation process was necessary in order to: a) Publicise and explain the Neighbourhood Planning process among Sele ward residents; b) Seek the opinion of the public on the improvements needed in the area, and feedback on the proposed objectives and policies of the Plan. 4. The document sets out the steps taken to engage and consult with the community in Sele ward and presents how the opinion of the public has influenced the writing and amendment of the Sele Neighbourhood Plan. 5. Hertford Town Council would like to sincerely thank all those who have contributed to the production of the Sele Neighbourhood Area Plan. The volunteers for this project spent many hours gathering data and proposing objectives and solutions for the Neighbourhood Plan, under the guidance of the Planning Consultant, Jacqueline Veater.

East Suffolk has beds of sand and clay deposited during the closing chapters of the series of geological epochs. In the region there are probably the greatest number of formations to be found in any such limited area. Basically everything rests on the Cretaceous chalk laid down over 70 million years ago. Locally there are at least 250' missing of the upper chalk which is represented on the Norfolk shore at Trimingham by the Ostrea lunata zone.

All rights reserved Coldfall Wood is interesting geologically because three different rock types underlie the surface. It is also bisected by streams into a valley that is far larger than would be possible with the present rate of flow. At the highest point abutting the cemetery and allotments glacial till is underfoot, overlying gravel that was transported by a river across what is now the London basin to join the Thames on its ancestral route further north. The bed rock is the London Clay that underlies most of London. Jurassic oyster from the till The Friends of Coldfall Wood www.londongeopartnership.org.uk www.coldfallwoods.co.uk/the-friends-of-coldfall-wood 1. London Clay c. 50-55 million years old The Solid geology of London is mostly underlain by a thick layer of stiff blue clay known as the London Clay. When it is seen in temporary excavations it is usually a rusty orange as the iron within it has oxidised. The clay was laid down as mud about 50 million years ago from rivers eroding the nearest coastline which was probably in the Midlands. Occasionally fossilised fruits and seeds of land plants such as the Nipa palm are found within the marine clay which indicate a tropical climate, but seeds of Magnolia suggest some seasonality.
