Ardross – St Monans

Ardross Castle. Photo: Angus Miller

The superb coastal exposures at St Monans demonstrate variety of Fife’s Carboniferous geology, and include the Ardross Fault which is well known for the number of volcanic necks along its length. We shall look at a section of the fault between St. Monans and Elie, and at the relationships between the necks, the fault, associated folding, and the host Carboniferous sedimentary rocks in the Pathhead Formation of the Strathclyde Group.

Berwick-upon-Tweed

The Ladies Skerrs dome, Meadow Haven, Berwick – Alison Tymon

This visit to coastal exposures around the town of Berwick-upon-Tweed will examine good coastal exposures of cyclothems, deposited in river deltas, swamps and shallow sea close to the equator. The strata include coal, fireclay, limestone and sandstone, some containing fossils. We will also examine structural evidence for the Berwick Monocline and associated faults, formed during the Variscan Orogeny. Note: this excursion is repeated from 2017, as part of a weekend visit by Yorkshire Geological Society; EGS members are welcome to attend, but transport from Edinburgh is not provided.

Pillow Lavas

Leadburn and Noble House

Excursion title:

Leadburn and Noble House

Please note for safety reasons this excursion will now not visit Leadburn Quarry but will instead focus on the Noble House quarry.

Date & time:

Wednesday 28 June 2017, 7 pm

Finish time:

9 pm

Leader(s):

Professor Brian Upton, University of Edinburgh

Excursion aims and description:

The rocks south of Leadburn are of Ordovician age, and include turbidite sequences formed on the floor of the Iapetus Ocean. These sedimentary rocks are visible in a quarry near Leadburn, and were formed in huge submarine fans which contain evidence of the processes involved and the source of the sediment. In contrast, volcanic activity on the sea floor around 450 million years ago formed pillow lavas with interbedded cherts, that can be observed near Noble House on the A701.

Transport:

Private car

Start place & time:

Penicuik, main public car park (opposite Lidl) @ 7pm. Car sharing from here is encouraged.

First locality:

Noble House Farm NT 184 501. Parking is limited and there will be a charge of £2 for each car.

Excursion route:

Visit a small disused quarry at Noble House, there is a 15/20 minute walk up to the quarry with pillow-lavas and chert beds. Walking distance of about 700m.

Geology Walk: Vogrie to Crichton Castle

Date & time:

Sunday 5 August 2018, 10 am

Finish time:

2 pm

Leader(s):

Lothian and Borders GeoConservation

Excursion aims and description:

The wooded banks of the River Tyne near Vogrie conceal an interesting industrial history, where both limestone and sandstone have been quarried extensively. Both Crichton Castle and the Kirk are built of local sandstone, deposited by rivers in the Carboniferous Period. Nearby, on the east and west banks of the River Tyne, the North Greens Limestone was worked, in quarries shown as abandoned on the 1892 OS map. The limestone was burnt in nearby limekilns.

This walk is organised by Lothian and Borders GeoConservation as part of Midlothian Outdoor Festival 2018.

Where to meet:

Vogrie House, Vogrie Country Park EH23 4NU. Note this is 5 minutes walk from the car park, which has a £2 parking charge.

Excursion route:

From Vogrie House, descend to the River Tyne and follow it south, via the Currie Lee limestone quarries, to Crichton Castle. Return on the west bank of the river.
