Accommodation (back to top)

 The conference hotel is the Holiday Inn. Please book using these links:

Aberdeen University Express

£50.00 per room per night including breakfast (Continental plus Sausages, Bacon, Scrambled Eggs and Beans)

Aberdeen University Holiday Inn

£57.00 per room per night including full Scottish breakfast

There are plenty of other accomodation options both nearby in the centre and around the University. Staying in the centre or near Old Aberdeen is fine. Further than this, and commuting will become troublesome for you.

Getting to the Venue from the Hotel (back top top)

The main meeting venues look like this:

Library - venue Day1


Library - Venue First Day MacRobert - Venue Second-Fourth Day

There is a campus map here.

I suggest this route:

Route to Venue


Your walk is above. It takes you through a nature reserve, past a drillsite, over a bridge so old nobody knows who built it, past Thomas Glovers Aberdeen House and then into sacred ground where you should be safe. Its 30 – 40 minutes. I gave you two routes so that you don’t draw attention; leave the Kelpies and Bogles alone and they won’t menace you. Don’t go under the bridge and stay out of the caves.

 If it rains we’ll run a shuttle.

Travel to Aberdeen (back top top)


Aberdeen International connects to lots of nice places: Paris, Frankfurt, Amsterdam, Dublin, Bergen. It also connects to London airports.



A pleasant 3.5 hour journey from Edinburgh or Glasgow, with trains about every two hours during the day.

To London is about 9+ hours, and you also have to go to London in the first place.

Rail from Newcastle and Manchester, if you flew there is also reasonable and takes about 6+ hours with journeys every two hours or so.

Travel by rail in the UK is expensive, crowded at busy times but otherwise safe. Northern Britain, in daylight, is quite pleasant by rail as the views are nice and picturesque.

Book train tickets here



By car from Newcastle, Glasgow, Manchester or Edinburgh would be ok, particularly once you escape central Scotland (Edinburgh and Glasgow). You would want a GPS (you can’t rely on good phone signals truly in the wilds – if this is why you have a car), but this would be perfect for exploring Northern Scotland. Forty-Freeway Minutes North of Edinburgh and Glasgow the traffic density drops and its about 3 hours of driving.

Field Trips (back top top)

The trips are designed to run together to provide an introduction to highland geology, as well as a run through of some of the work my research group got up to in the last 10 years in the areas of Precambrian Geology, Impact Geology and a Little Geofluids and Geochemistry. We will also see some structural analogues for the Nankai Accreationary Complex.

The Highlands can you give you all kinds of weather in a single day, so you will need hiking boots, spare socks, spare jumpers and a raincoat that could be dried quickly, should it rain...

There will be a deadline after which I will have to sort out accommodation and transport. This will basically limit numbers. I expect this will limit us to 20-25 people.

Expected cost is about 250-350 GBP.

Schedules are tenative until numbers are confirmed


Monday 4th June

  • Precambrian Impact Deposits
  • Precambrian Geobiology (Psudo-Stromatolites)
  • Life styles and habitats in Precambrian Lakes

The area is beautiful and remote, and the fieldsites unique and interesting.

Lunch: Pies

Dinner: Ullapool.

Wednesday 6th June

0930 – Highland Geology Field Trip – Lead by Stephen Bowden

  • Knockan Crag – Moine Thrust
  • Glencoul – Detachment Surfaces
  • Assynt – Tripple unconformities and Imbrication
  • Scourie – A bit of Lewisian
