Monday 8th
Dave Green - The Geology of Norway (and Scandinavia)
When
Mon, 8 January, 19:30 – 21:30
Where
Wynstones School, Stroud Road, Whaddon, Gloucester (map)
Description
Scandinavia forms a large part of the ancient continent of Baltica. Although once extensively covered by Phanerozoic rocks, these have been largely eroded apart from those preserved in downfaulted graben (as in the North Sea and Oslo) and upththrust nappes, pushed onto Baltica during the violent collision with Laurentia in the Caledonian Orogeny at the end of the Silurian. Otherwise, Scandinavia is composed of PreCambrian rocks (mainly igneous and metamorphic) accreted to Baltica during its formation, from 3500 to 900 million years ago. The course aims to introduce you to this long and fascinating history. Monday 8th for 10 weeks (not 12h or 19th Feb) until 26th March. Held at Wynstones School, Stroud Road, Whaddon, Gloucester from 7.30-9.30pm on Mondays . Cost £70

Thursday 11th
Dave Green - Mountain Building
When
Thu, 11 January, 19:30 – 21:30
Where
The Chantry, Thornbury (map)
Description
This 10 week course aims to introduce you to the geological processes that produce mountains, mainly by the study of different examples, both past (e.g. the Caledonian and Variscan belts) and present (e.g. the Alps and Andes). This includes the classic collisional orogenies, such as the Himalayas, Urals and Pyrenees; the accretionary orogenies, such as Taiwan, the Southern Uplands and the Andes; but also mountain ranges produced by very different tectonic forces, such as the East African Highlands, the Cantabrian Range and the Scottish Highlands. Held at The Chantry, Thornbury. First meeting 7.30 – 9.30, Thurs 11th January until March 22nd (not Thurs 15th Feb) in the ?TBA Room.Cost £75

Course Programme
Introduction and early ideas about the origins of mountain ranges
Plate Tectonics and an overview of the anatomy of a “typical” orogenic belt, in plan and in section. Tectonic zones, arcs and oroclines. Uplift and collapse.
Island Arc – continent orogenies such as Taiwan today and the Palaeozoic Grampian Highlands.
Andean (Cordilleran) mountain belts, such as the Andes, Rockies today or the Cadomian (Ediacaran-Cambrian) orogeny in the past
Continental Collision Zones, such as the Himalayas and Alps today, or the Caledonian (mid Palaeozoic) and late Palaeozoic Variscan belts.
Intracontinental orogenic belts, such as the Tienshan and Petermann belts today. The status of mountainous areas like Norway, the Cantabrian Range of Northern Spain and the East African Highlands.
Metamorphism and Plutonism in orogenic belts
Orogenic collapse, Channel Flow, Gneiss domes. The instability of Mountains.
Erosion and Exhumation of Orogenic Belts.
Historical change in the processes of mountain building, and the role of the supercontinent cycle
Useful Reading:
There is a [very good] text book exclusively about this subject “Orogenesis – the making of Mountains” by Michael Johnson and Simon Harley, published by Cambridge 2012.
A useful little book in the “Very Short Introduction“ series, published by Oxford 2015 is “Plate Tectonics” by Peter Molnar
Another useful book, not just for this course, is “The Making of Europe – a geological history” by Graham Park, published by Dunedin 2014.
In addition/alternatively, I enclose a dropbox link to various relevant books and articles, of varying degrees of accessibility:

Saturday 13th
South Wales GA - Holiday Geology
When
Sat, 13 January, 11:00 – 16:00
Where
National Museum Cardiff (map)
Description
This is a chance for all you budding speakers to come and entertain your fellow members with tales of geology seen on your travels or anything else with a geological flavour, no matter how tenuous, that you think will be of interest. I will be looking for about 8-10 'volunteers' to fill the day's programme. Each talk should be for a maximum of 15 minutes but can be shorter if you wish. The meeting is now only six weeks away and to date I have only had two volunteers so there are still plenty of slots in the programme. So that I can plan a balanced programme for the day it would be appreciated if you could let me know the topic of your talk at least a day before the meeting.
We will be providing tea and coffee from about 10.15am but you will have to makeyour own lunch arrangements. You can eat a packed lunch in the meeting room orthere are other options, such as the museum restaurant next door or various othereating places in the city centre. In order to make sure that we have enoughrefreshments can you please let me know that you will be attending by 10th Januaryat the latest. We will have our usual book stall and there will be space for smalldisplays so if you would like to display anything
