Day Excursion Programme

Day excursions 2017

We have a varied set of excursions for this summer and hope that you will find something that interests you. Booking instructions can be found in the February newsletter (newsletter 159/3). Please email the day excursion secretary at daytrips@gsocg.org for an electronic version of the application form and the address to which the completed form and cheque should be sent. As usual, the number of places available on the excursions is limited by the size of the bus, so please return your booking form as soon as possible to avoid disappointment.

Saturday 3rd June.  Kilewnan Burn and Dunmore from Fintry village
Joint Excursion with the Edinburgh Geological Society
Walk on footpaths, 4km total; hill ascent to 250m; walk along stream section; visit to old quarry. Walk to and along Kilewnan Burn. Walk up hill to top of Dunmore, then downhill and across hillside slope towards Fintry quarry. 
The Fintry Hills are part of the Clyde Plateau Volcanic Formation to the south-west of Stirling, and show good examples of varied basaltic igneous rocks that formed close to eruptive centres, in a landscape of craters and cinder cones. As well as the igneous rocks, we shall also be looking at Carboniferous sedimentary rocks of the Clyde Sandstone Formation and the Ballagan Beds (cement stones).
Toilets will be available in Fintry at the start and finish of the excursion.
The excursion will be followed by high tea at the Fintry Sports and Recreation Club, in company with our Edinburgh colleagues.
See Excursion 10 in the Stirling & Perth Guide (Browne & Gillen, 2015, EGS).
Leader: Dr Con Gillen
Leaving Gregory Building at 9:00, returning at 19:00, travelling by coach
 
Saturday 10th June. Tyndrum/Glen Orchy
We will visit the former lead mine some 1 km west of and 150 m above Tyndrum Lower station and examine the mineralisation and the country rocks into which it was emplaced. The mineralisation consists of mainly vein quartz with sphalerite  and galena. Other minerals which may be found are: chalcopyrite, pyrite, barite, and calcite. In the afternoon we shall make four stops along a generally level path in Glen Orchy where we shall see the Meall Garbh Psammite of the (lower) Grampian Group and the overlying Beinn Udlaidh Quartzite and Coire Daimh Pelite of the Appin Group.

Saturday 24th June. Glasgow Museums Resource Centre
This morning excursion is a guided tour of the Glasgow Museums Resource Centre at 200 Woodhead Road, South Nitshill Industrial Estate, Glasgow G53 7NN. You will need to arrange your own transport. The centre is about 5 minutes walk from Nitshill railway station. Museum staff will be showing us some of the many items in the geology collection which are not on public display. Because of restricted space within the building, numbers will be limited to 15 but, in the event of higher demand, a further trip will be offered on another occasion. There will be no charge for this excursion.
Leader: Ann Ainsworth
Meet outside the GMRC at 10:15 for a 10:30 start (own transport).
 
Saturday 22nd July. Comrie including Highland Boundary Fault and Earthquake House
Comrie lies on the Highland Boundary Fault and has been called the “Shakin’ Town” because of the frequent seismic activity there, especially during the 19th century. Our visit will focus mainly on the geology in the Grampian block immediately to the north of the fault where we will explore beautifully exposed examples of contact metamorphic changes to the Dalradian Aberfoyle slate adjacent to a late Caledonian diorite intrusion, the Comrie pluton at Craig More. We will visit the famous “Earthquake House” by The Ross, just west of the town and see an early example of a seismometer. In the afternoon we will take a walk from Comrie along Glen Lednock to see the De’il’s Cauldron waterfall where the River Lednock has incised a rock-cut gorge, and finally return to the Comrie pluton to examine the igneous rocks themselves and their contact relations with the country-rocks. Comrie has some excellent opportunities for cake, and if we are not too long delayed on the rocks we may wish to explore these, too! The trip will involve a few kilometres of variably rough and boggy walking, sometimes quite steep for short intervals.

Saturday 29th July. Little Glen Shee, Dunkeld
The excursion is an opportunity to examine Dalradian rocks (slates and grits of the Southern Highland Group) and structures related to the Tay Nappe, a structure that has produced folds at various scales. The area is close to the Highland Boundary Fault and the Highland Border steep belt (or “downbend”'), followed to the north by the flat belt of the structure.
Toilets will be available in Dunkeld at the start and finish of the excursion.
See Excursion 18 in the Stirling & Perth Guide (Browne & Gillen, 2015, EGS).

Saturday 19th August. Solway coast - Southerness to Powillimount
The coastal section from Southerness to Powillimount within the Kirkbean Outlier forms part of the northern margin of the Solway-Northumbrian Basin which lies between the Southern Uplands to the north and the Lake District to the south. The northern margin of the basin is locally formed by the North Solway Fault, the basin itself being an extensional basin active during the Early Carboniferous (Dinantian). Synsedimentary faulting, downthrowing to the south, combined with cyclical sea-level changes to produce a wide range of sediments from open, shallow marine limestones and mudrocks to floodplain sandstones, silts and coals as the basin-fill developed. Faunas and floras responded to these changing conditions, and the excursion will track these responses and their resulting ecologies, as well as the various sedimentary structures to be seen, and also the tectonic structures imposed on the basin during the Late Carboniferous. Around 2 km of easy coastal walking.
