Trip update

December lecture "Expedition volcano" by Prof. Chris Jackson

In June 2017, 15 scientists and BBC film crew travelled to Nyiragongo, one of the largest and most active volcanoes in the Democratic Republic of Congo, and home to the largest permanent lava lake on Earth. Posing a permanent threat to the city of Goma, a settlement with >1,000,000 people, Nyiragongo last erupted in 2002, and has been intermittently active ever since.

In this talk Prof. Jackson, who took part in this expedition, will describe the overall geological setting of this lethal yet mysterious volcano, which is situated within the East Africa Rift, the giant geological fracture responsible for the splitting apart of Africa. He will show footage and photography taken from the volcano summit and deep within the crater, next to the 700 m wide, 600 m deep lava lake, showcasing the volcano's structure, and the unusual chemistry and physical properties of its lava.

Transmitted on BBC2 in October 2017, Expedition Volcano discussed much, much more about the geology and study of this fascinating yet devastating natural wonder, the threat it poses to the nearby populous, and the great wealth and conflict it has brought to this turbulent region.

Register for this fascinating lecture via the registrion form - link above in the menu.

GA Logo

Geologist's Association Festival of Geology

The Annual GA Festival of Geology takes place on Saturday 3rd November 2018 at UCL, with field trips on Sunday the 4th.

LOUGS always has a stall there, joint with the National Society, and you can expect many other local groups, societies, sellers, speakers and more. See the flyer here for more details. Hope to see you there!

Trip update

Bognor Foreshore trip on 14 July : Change of Start details

This trip wil now start from 11:30am at St Mary Magdalene church, Bersted Street, South Bersted, Bognor Regis PO22 9QB. Grid Ref.: SU 9347 0022. Roadside parking

The foreshore exposures of Palaeogene geology at Bognor Regis include two geological SSSIs, which have yielded nationally important fossil material from the London Clay and Reading Formations. A good low tide is required, constraining a beach visit to late afternoon / early evening, so the day will commence with visits to two medieval churches to look at the history of the area and use of local building stone.

Longer trip 2019 announced : The Scottish Borders

The Scottish borders are notorious for witnessing the death of an ocean. As such they are the perfect place to interrogate, in an attempt to understand what happened as the oceanic sediments of the Ordovician and Silurian Iapetus Ocean were sliced and folded into the suture of the first physical union of England and Scotland.

More details can be found in the "Upcoming Events - Longer Trips" section.

Past Events Archive Online with Interactive Map

The archive of event reviews published in London Platform between 2001-17 is now online. You can use it to get a better impression of what we do, to get ideas for self-led days out, or simply browse. Use the interactive map to explore areas of interest : Interactive Map.

There are lots of interesting lectures and trips planned for this year. Be tempted by the list in the events section and register using the form.

London Pavement Geology

London Building Stones App now available - it's free!

The "London Pavement Geology" App is now available to download free from the iTunes App store for iPhone & iPad, and from GooglePlay for Android. It archives well over 1000 building stone localities within the M25. You can view these from the App and also submit new locations. Please do spread the word – and please do submit new locations!

Both can also be downloaded from the website via the links:

OU OpenLearn


A useful resource provided by the Open University is OpenLearn giving everyone free access to OU learning materials. The project, launched in 2006, contains more than 8000 study hours of learning materials across all disciplines.

From LearningSpace, there is a topic index. The "Science" component contains chapters or sections of current OU science courses (level 1 to postgraduate) as well as some of the discontinued courses (for example S182 Studying Mammals and S278 Energy Resources).

If you register on OpenLearn (also at no cost) you can participate in associated online activities and forums and keep track of the courses you have looked at, alternatively, you can just (anonymously) browse through the content.

Additional free resources can be found on the Open University channels on YouTube and iTunesU.

The OU is also part of the OpenCourseWare Consortium where you can access course materials from contributing universities across the globe.

Gilberts Pit new entrance

New access at Gilbert’s Pit, Charlton unveiled on 18th May 2016

Gilbert’s Pit SSSI (Site of Special Scientific Interest) at Charlton in Southeast London is one of a number of former quarries worked in this area for their sand, gravel and chalk. This pit was primarily worked for the Thanet Sand used for moulding at the Woolwich Arsenal foundries and glass manufacture. Notified as an SSSI in 1953 it represents the only permanent exposure in the Woolwich area of the Woolwich Formation.

Steps have been built up the east side of the quarry face, LOUGS members assisted in preparing the area on our Conservation Days in 2013 and 2015. Click here for futher details, and photos.

Building Stone England

Building Stone in England

The BGS have recently completed the first phase of a project with English Heritage to find Building Stone in England. [Apologies to those in Scotland, Wales, Ireland and Europe!] The background to the survey may be seen here.

You can download some guides to the stones used in your area, together with the free data files here. There is a webGIS using this data here, where you can see the coverage to date.

The data and information has mostly been provided by local consultants, employed by English Heritage, who are familiar with the area. If, however, you spot something you want to amend or add, please let them know, addresses are on the webpages. Constructive criticism welcomed!

For Northern Ireland, see for another approach.

New OU website for International Students

International Students

The Open University have recently launched a new website for international students, hopefully making it as easy as possible for overseas students to find all of the information they need about OU courses, including the BSc (Hons) Environmental Studies and BSc (Hons) Natural Sciences. This can be found at the following web address:
