Gritstone edge, Stanage, Peak District

The East Midlands Geological Society was formed in 1964 by a group of professional and amateur enthusiasts, who recognized the need for such a group in this area of great geological interest. This mix of people from all backgrounds has remained a feature of the Society to this day and gives it a friendly relaxed atmosphere which appeals to newcomers. We are based in Nottingham, are affiliated to the Geologists’ Association, and enjoy cordial relations with other geological societies and with the British Geological Survey at Keyworth.


The Society is open to all and welcomes new members with:

  1. + Six lectures each year
  2. + Six field trips each year
  3. + The Mercian Geologist, our scientific journal
  4. + Regular news letters
  5. + Information on geological events

While the main activities of the Society are aimed at furthering interest in geology, the social side a Christmas buffet after the December meeting and also an annual dinner. The Society holds its indoor meetings at Nottingham University, to which we remain indebted for the use of their lecture theatre in the School of Geography. The East Midlands Geological Society is open to all, and we maintain interests and links with local geology and also with the wider geological sciences; new members are always welcome.

Gritstone edge, Stanage, Peak District

MERCIAN GEOLOGIST : Once a year the society publishes the Mercian Geologist, its own journal, compiled by an editor who is a member of the Council. Papers are invited and published on all geological topics and whilst items on East Midlands geology are especially welcome, there is no restriction on the scope of papers considered. In recent years the journal has been refurbished and remodelled to give a more modern look, and now has more news features, informal reports and comment. The editor is pleased to receive non-scientific input from members on the society's affairs.

Mercian Geologist - notes for contributors

LANDMARKS OF GEOLOGY : The Society publishes the "Landmarks of Geology" series from the Mercian Geologist in the Local Geology section, and invites you to use this valuable source of reference. The series will continue to grow with successive items in our journal. Any reference to these items should cite the Mercian Geologist and the issue that they originate from, and not this website.


Mercian Geologist journals are now available to download for all EMGS site visitors - Click here

The later issues go online a year after their initial publication. For the current issue, printed copies are available as above from the secretary.

The archives are now in preparation, and complete runs will only be available some time in the future.

An index for Volumes 1-12 (1964-1991) was issued as Volume 12, Number 4.

Celebrating the Origins of Animal Life: Building a UNESCO Global Geopark in Charnwood Forest, UK
Saturday, 13th January 2024 - 6pm
Dr Jack Matthews, Geoheritage Conservation and Interpretation Officer, Charnwood Forest Geopark

Charnwood Forest in Leicestershire is host to some of the oldest animal fossils in the world, many of which have been key to our understanding of the rise of animals during the Ediacaran period around 570 million years ago. In addition to its internationally significant palaeontology, the area is also home to a number of working and historic quarries whose lithologies have shaped the built environment of the United Kingdom for more than 2000 years. This presentation will outline the internationally significant geodiversity of Charnwood Forest - including the outstanding ancient fossils - and the ways it has shaped the landscape, communities, and people of Britain’s ‘unexpected upland’.

Diamond Geology
Saturday, 10th February 2024 - 6pm
Dr Tony Waltham, President, East Midlands Geological Society

In both their geology and their industry, diamonds are like no other mineral. For centuries, the world’s supply came almost entirely from the alluvials of Golconda in India. Only in 1870 were kimberlite pipes discovered, and it was a long time after that before their gas-rich explosive origins were really appreciated. The main source of gem-quality stones switched to Kimberley in South Africa, but this has subsequently been displaced by Botswana, Russia and then Canada. Exploration for diamond-bearing pipes continues today, and has involved some exciting stories with both lone prospectors and major companies.

Geology of Stonehenge and the Bluestone controversy
Saturday, 9th March 2024 - 6pm
Professor Peter Worsley, Emeritus Professor of Quaternary Geology, University of Reading

Stonehenge has recently come into the public eye due to the publication of the results of new geochemical work. The Sun newspaper declared ‘Mystery of where the giant rocks came from SOLVED’ whereas The Guardian was more cautious with a headline ‘Archaeologists discover likely source of Stonehenge’s giant sarsen stones’. The senior English Heritage properties historian said that she was delighted that one of the most intriguing questions about Stonehenge had been answered. The background to this euphoria will be critically examined and the geological fundamentals reviewed.

Apart from the sarsens, the other geological problem lies with the assemblage of ‘foreign’ rocks incorporated into the henge structure, i.e. the so-called Bluestones. There now appears to be little doubt that the Bluestones are primarily derived from outcrops in south-west Wales but the mechanism whereby they arrived to Salisbury Plain is far from being resolved. Most archaeologists have accepted the hypothesis that Neolithic people were responsible for the transport of the Bluestones from their source to the plain but over time the favoured routes have changed drastically. In contrast geologists have been split between those who accept the human transport mode and those who favour natural earth surface processes as being responsible for transportation – i.e. glaciation. The strengths and weaknesses of these competing ideas will be discussed.

This lecture will be preceded by the EMGS Annual General Meeting.

The Lower Cretaceous ‘East Lindsey Group’ – a jewel in the geological crown of Lincolnshire
Saturday, 13th April 2024 - 6pm
Paul Hildreth, General Secretary and Past President, Yorkshire Geological Society

The county of Lincolnshire is often overlooked as a venue for geology field trips and even research but it possesses several opportunities for examining significant and interesting exposures. The Elsham Sandstone is a unique, local deposit within the Kimmeridge Clay Formation and at Welton-le-Wold neighbouring sites offer exposures of three glacial tills and an interglacial gravel deposit. 

The county’s jewel in the crown however is the under-published Lower Cretaceous sequence coeval, at least in part, with the very well-known Wealden Group of south east England and the enigmatic Speeton Clay of Filey Bay. This ‘East Lindsey Group’ is unique to Lincolnshire. It thins northwards to feather out north of Caistor and experiences facies changes in the area beneath The Wash which pass into an East Midlands suite transitional with those of the south of England. 

The impact of the ‘East Lindsey Group’ is threefold. It has influenced the shape of the western edge of the Lincolnshire Wolds producing an attractive fringing landscape between the broad Upper Jurassic (Oxfordian - Kimmeridgian) clay vale and the Chalk scarp. It has supplied three locally-important and distinctive building stones that can be recognised in the villages and towns of East Lindsey. It has provided the raw material, ironstone, for a relatively short-lived but locally important mining industry, the scars of which are still visible in the hillsides and valleys of the Claxby and Nettleton area. 

The various lithologies and palaeontology of the rocks comprising the ‘East Lindsey Group’ allow for a reconstruction of the palaeogeography of the Lincolnshire area during early Cretaceous times (145 – 113 million years ago) and its relationship with other parts of the present day United Kingdom.
