NE SCOTLAND
Saturday 6th - Saturday 13th April 2002
What we will see
There will be mostly metamorphic rocks, including Moine and Dalradian
metasediments but there are some unusual intrusive ultrabasic igneous
rocks and granites. Folding and faulting will be seen, in particular
Caledonian structures in Dalradian rocks. There are major
unconformities between Dalradian and Moine rocks and overlying
Devonian and Permo-Triassic sediments. Both Devonian and Permo-Trias
rocks are desert sediments so it will be interesting to compare them.
This area is geologically most complex, particularly the regional
metamorphic mineralogy. We will use guide-books and maps to try to
unravel the geology, largely looking at road cuttings and coastal
exposures. The Aberdeen Area geological guidebook will be useful for
sites to the east of Forres. There are some sites which we will have
to discover for ourselves, especially to the south of Forres in the
Grampians.
Useful maps are Landranger 27, 28, 29
Guidebooks
Geology of the Aberdeen Area, by N.H. Trewin, B.C. Kneller, C. Gillen
published by the Geological Society of Aberdeen has many useful
itineraries.
How we will get there
There is a good train service to Inverness which we can reach
comfortably in a day. We will hire a minibus or car there to use for
the rest of the holiday. Going by train will limit the amount of
luggage we can take with us but the alternative is four days driving
from Huddersfield which would put too much pressure on the drivers.
We will be able to shop for food in Inverness before driving to
Forres. Drivers should bring their driving licences.
Where we will stay
I have booked self-catering log cabins at Rafford, near Forres.
The full address is Tulloch Lodges, Rafford, Forres, Moray. !V36 2RU.
They are set in woodland with a lake nearby. The site is in square
NJ0656. The lodges will be reasonably comfortable and warm, but
will probably not be luxurious. There is information, laundry
facilities and a telephone on the site but no other facilities.
There are shops in Forres which is 4 miles away. Bed linen is
provided but towels are not. Electricity is provided by £1 coin
meter.
What it will cost
About £160 per person which will cover accommodation and
transport throughout the trip. You will need to make your own
arrangements for insurance and food.
Proposed Schedule
This is tide-dependent to some extent.
- Elgin Museum has collections of natural history, geology and
archaeology including local reptiles and fish from the Devonian and
Permo-Triassic sandstones.
- Nairn Museum has a good collection of minerals and fossils from
Morayshire and from other parts of the North Atlantic province,
from Greenland and Scandinavia.
- Dalradian metasediments from Portknockie to Sandend.
They include many sedimentary and tectonic structures.
- Devonian and Permo-Triassic sediments from Burghead to Lossiemouth.
Faulted and unconformable junctions between the two and some
mineralisation.
- Clashach Quarry which has dinosaur trackways on red Permo-Triassic
Hopeman sandstones.
- Quarry Wood, near Elgin. Both Devonian and Permian rocks are found
here in adjacent quarries, so comparison of the two will be interesting.
- Dalradian of the Portsoy District The Portsoy group consists of
limestones, metapelites, calc schists and quartzites which have been
intruded by a basic to ultrabasic sheet and then metamorphosed and folded
intensely.
- Findhorn Gorge at Randolph's Leap near Logie (NJ0049) has Moine
gneisses and migmatites.
Places are limited and transport arrangements need to be finalised,
so please book as soon as possible.
