Volcanoes and the making of Scotland

Volcanoes and the Making of Scotland

/in /by
The next lecture of the Edinburgh Geological Society’s winter series will take place on Wednesday 23 November at 7:30pm in the Hutton Lecture Theatre at the Grant Institute of Geology, King’s Buildings, Edinburgh, when Professor Brian Upton, University of Edinburgh will talk about Volcanoes and the Making of Scotland.

Volcanoes have played a major role in the creation of Scotland’s geology. The most recent examples on the west coast are a mere 60 million years old, but rocks composing many of the famous Scottish landforms such as Glencoe are the direct result of earlier episodes of volcanism. Volcanoes and the Making of Scotland will explore back in time from the most recent examples to volcanoes of the obscure Precambrian times which left their signature in the ancient rocks of the far north-west.

Brian Upton is a Distinguished Fellow of the EGS and is Emeritus Professor of Petrology and Senior Honorary Professorial Fellow in the School of Geosciences of the University of Edinburgh.  The comprehensively-revised second edition of his highly-acclaimed book Volcanoes and the Making of Scotland has recently been published and has been enthusiastically reviewed.

The meeting will be followed by tea and biscuits in the Cockburn Museum of the Grant Institute, to which all are invited.

Volcanic Hazards

Volcanic Hazards

/in /by

The next lecture of the Edinburgh Geological Society’s winter series will take place on Wednesday 9 November at 7:30pm in the Hutton Lecture Theatre at the Grant Institute of Geology, King’s Buildings, Edinburgh, when Dr Charlotte Vye-Brown, BGS Scotland will talk about Volcanic Hazards. Of all the natural hazards, volcanic hazards are unique in the sense that there are many hazards associated with, and produced by, any single volcano that can have impacts hundreds or even thousands of kilometres away. Globally, an estimated 800 million people live within 100 km of a volcano that has the potential to erupt. There remain significant challenges to understand volcanic risk and assist with disaster mitigation. These challenges are pronounced in Africa due to significant knowledge gaps, lack of real-time monitoring, uncertainty, limited early warning capacity and pressure on resources. This talk will focus on recent research in Ethiopia on understanding the periodicity and character of past eruptions, identifying potential impacts, and evaluating future threat.

Charlotte Vye-Brown is a senior volcanologist with BGS in Edinburgh, working on projects on rift volcanism, particularly in East Africa; the volcanic history of the Ascension Islands; and emplacement and eruption styles of flood basalts.

The meeting will be followed by tea and biscuits in the Cockburn Museum of the Grant Institute, to which all are invited.

Paleosols as evidence of terrestrial climate change.

Palaeosols and Climate Change

/in /by
The next lecture of the Edinburgh Geological Society’s winter series will take place on Wednesday 26 October at 7:30pm in the Hutton Lecture Theatre at the Grant Institute of Geology, King’s Buildings, Edinburgh, when Dr Tim Kearsey, BGS Scotland will talk about Palaeosols as evidence of terrestrial climate change at major Palaeozoic vertebrate evolutionary events.
Climate change is a major driver of evolution. Palaeosols (fossil soils) are one of the few direct indicators of terrestrial climate and provide a record of climate changes and landscape architecture, and are critical in understanding the terrestrialization of vertebrates in the Carboniferous and the Earth’s largest mass extinction at the end of the Permian.

Tim Kearsey is a survey geologist and sedimentologist with BGS in Edinburgh. He has research interests in Palaeozoic stratigraphy and sedimentology; palaeosols and palaeo-environmental reconstruction; and geostatistics. In June 2015 he was joint leader (with David Millward) of the highly successful EGS excursion to Burnmouth.

The meeting will be followed by tea and biscuits in the Cockburn Museum of the Grant Institute, to which all are invited.

Power of Our Planet

/in /by
On Saturday 22 October 2016, starting at 10:00am, the British Geological Survey will be holding a one-day Science Showcase entitled ‘Power of our Planet‘ at Dynamic Earth in Edinburgh.  There will be a wide range of demonstrations and hands-on activities for all ages and levels of interest.  This year, this event replaces the popular BGS Doors Open Day, now sadly no more since the closure of Murchison House, and it will provide a great opportunity for members of the public to meet and engage with geologists and their work.
Everyone is encouraged to support this event and to publicise it to family and friends.
The ‘Power of our Planet’ event is free to attend; admission to the main Dynamic Earth galleries, if desired, will incur the usual admission charges.

Fluvial Channel Reservoirs

/in /by

The first evening lecture of the Edinburgh Geological Society’s winter series will take place on Wednesday 12 October at 7:30pm in the Hutton Lecture Theatre at the Grant Institute of Geology, King’s Buildings, Edinburgh, when Prof Patrick Corbett, Heriot Watt University will talk about: Fluvial Channel Reservoirs – 20 years diagnosing their reservoir engineering attributes.

In 1994 the first study was undertaken to collect permeability data from opencast or surface mines in the Ayrshire Coalfields with the specific objective of generating synthetic well test responses. Well tests are undertaken by engineers on making a discovery in a fluvial reservoir to try to understand the lateral extent and size of the reservoir. At that time the tools for doing the simulation were rather simple, the models produced were rather simple and the results looked rather like the expected results in the engineering textbooks at the time.  Since then, as the data and understanding have improved, as Google Earth has provided images of fluvial systems across the world, as the simulators became more powerful, the grid blocks smaller and the models much larger, and more well tests have been conducted, we begin to see that the 3-D pressure responses are much more complex. This goes, in some way, to explain why fluvial reservoirs have lower recovery (and therefore higher remaining potential) than many other types of oil reservoir.  Twenty-two years later, we are still studying opencast mines in Ayrshire (the Spireslack Mine), building models and trying to understand fluid flow in complex reservoirs.

Patrick Corbett is Professor of Petroleum Engineering at Heriot Watt University and Head of the Carbonates Reservoirs Group. His long-term research interests involve integration of reservoir geoscience, petrophysics, geophysics and reservoir engineering.

The meeting will be followed by tea and biscuits in the Cockburn Museum of the Grant Institute, to which all are invited.

South Queensferry and Siccar Point

/in /by
A reminder that there are two EGS excursions this week:

Wednesday 22 June
South Queensferry Shore

Leader Richard Smith, Lothian and Borders Geoconservation
Meet at 7pm opposite the Hawes Inn (where the pier joins the B924) – NT 136 783. Own transport.
Saturday 25 June
Cove, Pease Bay & Siccar Point, East Lothian
Leader Angus Miller, Geowalks
This is the annual Joint Excursion with the Geological Society of Glasgow
Transport will be by coach from Waterloo Place at 10.00 am (NOT the usual 9.00 am) with an extra pickup point at Milton Road to Cove. Pickup at the end of the day from Siccar Point Car Park on the entrance road to RK Drysdales Factory TD13 5YS, returning about 6pm after High Tea.
Further details of these excursions, including information on routes, main features of geological interest, and level of difficulty, can be found on the EGS website athttp://www.edinburghgeolsoc.org/x_home.html .
Please note that you will need to book for these excursions – contact Mel Farquharson on excur…@edinburghgeolsoc.org or by telephone 0131 552 3452.  This is especially important for the Saturday excursion to ensure that there are sufficient places on the coach, and also to pre-order from the menu for High Tea, as confirmed orders are needed asap.
