Mineral display October 2023

SUNDAY 1ST OCTOBER 2023

FROM 12.30 PM TO 6.00 PM

Cumbria Amenity Trust Mining History Society (CATMHS)
Mineral Display


Members of the Society are hosting a mineral display in the Wesley room at Ambleside Parish Centre. This is a rare opportunity to see beautiful specimens collected mainly from mines in Cumbria and Weardale, one of areas traditional industries which helped shape it as it is today. There is the opportunity to discuss, understand minerals and their formation.
Entry free with Tea & Coffee provided. Donations welcome in aid of Ambleside Parish Centre

Anyone is welcome to bring along their material specimens along to show and have them photographed.

Linarite – Red Gill Mine, Caldbeck
Fluorite – Rogerley Mine, Weardale

Event Reminder: Deformed Dirt: research on the deformation caused by glaciers and ice sheet

Wednesday 20th September 2023
Time: 19.30hrs
Friends’ Meeting House, Elliot Park, Keswick. CA12 5NZ.
Prof Emrys Phillips PhD, MSc, CGeol FGS, FRGS
Deformed Dirt: research on the deformation caused by glaciers and ice sheets

The deformation caused by glaciers and ice sheets, known as glacitectonics, produces folding and faulting structures similar to those found in orogenic mountain belts but on a smaller scale and shorter time scales. The lecture will include a brief history of glacitectonic research, examples from around the world of the range of landforms and features formed as a result of glacitectonism and discuss why understanding these glacial deformation processes are so important.

Professor Phillips will be known to many members as he has given talks and led field trips for us. He is Individual Merit Research Scientist (Quaternary/glacial sciences) at BGS and Honorary Professor, School of Energy, Geoscience, Infrastructure and Society at Heriot Watt University

Event Reminder: Burtness Comb rock slope failure (Lateglacial rock avalanche)

Start: 10.00am at the cash pay-and-display car park at NY 195150, opposite Gatesgarth Farm (Buttermere). You will need about four £1 coins to pay.

Dr Peter Wilson, Ulster University

Itinerary: Initially a flat valley-floor walk of c.1 km from Gatesgarth Farm to Horse Close alongside Buttermere. Then a steep grassy slope up into Burtness Comb (c. 1 km and c. 400 m ascent). Once in the Comb the terrain becomes increasingly bouldery. The nature and source of the rock avalanche debris will be discussed and recently obtained surface exposure ages will be presented. Other features of geomorphological interest will also be discussed.

The rock avalanche is described in the following papers:

Clark, R. & Wilson, P. 2004. A rock avalanche deposit in Burtness Comb, Lake District, northwest England. Geological Journal 39, 419-430.

Wilson, P. & Jarman, D. 2013. The Burtness Comb rock avalanche, English Lake District: a rare case of rock slope failure – glacier interaction. Proceedings of the Geologists’ Association 124, 477-483.

Meeting 20th September 7.30 at Keswick Friends Meeting House

A table has been booked at the Cassa Bella restaurant in Keswick for 6 people including the speaker before the lecture. We are now unable to book a large table together so if anyone would like to organise booking their own table there is an online booking system at www.casabellakeswick.co.uk

The booking form has a ‘Notes’ box so it may be worth asking for a table near the table that’s already booked or at least ask to be in the same room. (Booking Ref RVWWDF in the name of Bethan Steele from 17.45pm). We hope to see you there.

Event Reminder: Coombe Crag Gorge

Saturday, September 16, 2023    10:00

CGS Risk Assessment Coombe Crag 2023Download

Leader Steve Rozario

Meet at 10.00am at  Banks East Turret Car Park: https://www.english-heritage.org.uk/visit/places/banks-east-turret-hadrians-wall/directions/ £2 parking charge, free for English Heritage members.

The purpose of this excursion is to examine the regional geology and the sedimentology of the Leahill Cyclothem, a minor Yoredale Group cyclothem, and the picturesque, postglacial incised Coombe Crag Gorge, near Brampton. Full details of the excursion will be published in the new Geologists’ Association guide to Cumbria. The excursion is a 6 km walk on waymarked public paths, with 200m of ascent and descent, and will take about 4 hours. The paths can be muddy when wet, there are sections through woodland with exposed tree roots and paths along the sides of a steep river gorge. One section has steep drops on both sides and may be difficult for vertigo sufferers, although this can be bypassed if needed. Boots or stout walking shoes should be worn. A packed lunch is recommended.

We will see:

– a short section of Hadrian’s Wall and a Roman Quarry

– a cyclothem succession of fossiliferous marine limestone, offshore mud, and a prograding delta.

– channel sandstones and overbank deposits

– a gorge carved by glacial meltwater with an incised meander
