Dave Green - Geostudies

Geostudies is run by Dave Green, a self-confessed geological enthusiast, who simply likes to pass it on! He has taught Geology at various levels, from O level to undergraduate, since 1974, at various institutions; secondary schools in Gloucester and Ross, Further Education Colleges in Stroud, Swindon, and the Forest of Dean, the WEA, the Open University and, for the last 12 years, the University of Bristol. He is an all-round geologist, but inclines towards agreeing that he is keener on the “hard rock” side of geology (older sediments, igneous and metamorphic rocks, geological structures etc.) but has a more than passable knowledge of soft rocks and their fossils, and is very interested in Quaternary geology and the development of landforms. It would be fair to describe him as “laid back” and patient in his approach, and keen to make sure that students are grasping ideas in a subject that can sometimes be fairly inaccessible, often due to jargon. Above all he is enthusiastic about the subject, something that he hopes will rub off!

Dr. Nick Chidlaw

The tutor is a geologist with 30 years of post-graduate experience in teaching, research, publishing and industrial consulting. As a research student, he studied the sedimentology of Early Jurassic strata in the Cotswolds, carried out at the former St Paul and St Mary College Cheltenham (now the University of Gloucestershire), and the University of Bristol. During this time he taught undergraduates thin section petrography and field mapping skills (Arran, Lake District, Lizard). In the late 1980's he worked as a part time OU tutor on the Science Foundation course in Bristol. He has taught adult education courses for over 20 years, mostly during his time at Bristol University, and in recent years for Cardiff University.

Spring 2018


The Soudley Valley, deeply incised into the eastern flank of the Forest of Dean plateau, is a microcosm of the Forest's geological and industrial heritage. On this gently-paced circular walk, you will be able to hear about these aspects and examine them for yourself. Rock types ranging from those formed in hot deserts, shallow tropical shelly seas and swampy rivers are present, exposed in abandoned building stone and roadstone quarries, and railway cuttings. The exteriors of abandoned limestone, iron and coal mines will also be visited. The walk will be approximately 2 miles in length, with frequent often extensive stops. Suitable for those with a little or no prior knowledge of geology, as well as the more-experienced.

Sunday 25th March 10am - 5pm : HOT DESERTS OF THE PAST

Since its formation some 400 million years ago, that part of the earth's crust that became the British Isles has slowly 'drifted' northwards by the agency of plate tectonics from the southern hemisphere to its present position. In doing so, it has passed through both hot arid latitudes either side of the equator. This course looks at river and floodplain deposits of Latest Silurian and of Devonian age, and desert screes of Triassic age, which were laid down under such climates. The course focuses on two excellent exposures which are designated geological SSSI's by Natural England either side of the Severn Estuary: Lydney Cliff about 10 miles upriver from Chepstow, and Kilkenny Bay at Portishead, near Bristol. In both exposures, contemporaneous calcareous fossil soils are preserved, which at Lydney are recognised as some of the best known globally. Both sites are tidal - the date and times being suitable for safe visits.

Saturday 15th and Sunday 16th April 10am - 5pm : Determining Geological Structure and History from Published Geological Maps

Those studying geology, either formally or informally, sooner or later will likely come across published geological maps and these, although often visually impressive with their variety of colours and complexity of drawn lines, can be daunting to interpret. The course is suitable for those with a basic overall knowledge of geology, as well as those with more experience. Attendance on the course should provide those present with confidence in successfully interpreting parts of many geological maps in the future, and so broaden their understanding of this key form of geological data communication. This course, arranged to run on the weekend of 3rd and 4th March, was postponed due to poor weather and travel conditions. Anyone who may have wished to attend the course on those dates but could not be available, may now be so for the rescheduled dates. Tuition fee is 45.00 per person

Undergraduate Courses - Geography
Honours Degree

The course emphasises the relevance of geography today and for tomorrow’s world. You’ll explore these and other issues in developed and developing world contexts.
Bringing together human and physical geography, the range of innovative modules allows you to specialise as the course progresses.
You’ll work in well-equipped laboratories and participate in fieldtrips to European countries and beyond. Recent trips have included Uganda, the Swiss Alps and Spain as well as numerous local destinations.

The degree gives you the skills and expertise relevant to key employment sectors. Education, geographic information systems, climate research, environmental management and sustainable development, are just some of the areas where graduates are now making major contributions.

The staff are passionate, committed educators and include many national award winners and internationally recognised authors and researchers.
