Dave Green - Geology and Landscape

When

Tue, 2 July, 19:00 – 21:00

Description

Geology and Landscape of Gloucestershire and surroundings 

A weekly field-based introductory course. 

No previous knowledge of geology is assumed Tuesday evenings 28thMay to 16th July 2019 

Gloucestershire is one of the most geologically diverse counties in Britain. 

The aim of this field-based course is to take you towards an 

understanding of local scenery.  We will look at the components 

- the highly diverse  rocks and their structure; and processes 

- weathering, slope forming and erosion - which have combined to produce this equally varied landscape - the materials from 

which the scenery has been sculpted and the processes that have acted upon them since the area emerged from the sea 65 million years ago 

(about the same time that the dinosaurs became extinct) 

No special equipment is necessary, apart from stout footwear and possibly waterproofs - although we will hopefully have six balmy 

summer evenings! Meetings are held on Tuesdays each week, 

(apart from breaks on Tuesday 4th and 11th June), meeting at 7.00 pm and finishing 

at 9.00 pm or later (whenever the party feels in need of refreshment !!) at the following meeting points (see over) 

Cost: £50 for 6 week course 

or £10 per session

2nd  July Glasshouse 

A complex area of geology, where relatively ancient Silurian, Devonian and Carboniferous rocks meet younger Triassic sediments along the Malvern fault system. The older rocks have been thrown into a series of folds, whose north-south trend is faithfully reflected in the landscape by the outcrop of relatively resistant and weak rock, forming ridges and valleys They have also been cut by a major fault (the Glasshouse Fault), bringing older rocks (Lower Silurian) in the core of the May Hill anticline next to them, with consequent effect on the scenery.  This fault is an example of a strike slip fault, with mainly horizontal movement taking place; a little similar to the present San Andreas Fault in California. Meet at the roadside downhill from the Glasshouse Inn (used as the car park for the pub) SO709214. We will look at the geology by means of a circular walk of about 3km with a climb of about 40m.

25th June Bixslade and Bixhead 

Bixslade is a steep valley cut into the steep dip slope of the Upper Carboniferous Pennant Sandstone to the west of Cannop Pond> For hundreds of years used as a building stone, there used to be a tramway down from the main quarry at Bixhead to the stone cutting works at Cannop; a tramway that was also used to transport coal, and iron ore from deposits within the Pennant, that were worked within Bixslade. We will traverse the route of the tramway and return on a circular route involving a walk of about 3-4km and a climb and descent of about 130m. 

Meet in the layby (old section of road), on B 4234 north of Parkend, near the Stone Cutting Works, Cannop, at SO 615 095

Description

Lower Lias (Lower Jurassic) faunas of the West Somerset Coast - seniorum et minimus.

Leaders: Dr Andy King and Dr Dave Evans

Location: Doniford (Helwell) Bay, Watchet, West Somerset

Date: June 30th 2019 (Sunday)

Type: Field Trip (Day)

Summary: An opportunity to explore the evolution of and biostratigraphical resolution achievable using these fossils (amongst the earliest ammonites recorded in Britain) and to see the unique in-situ 'Nautilus Islands' palaeocommunity.

More info:

This is a great opportunity to explore the evolution of and biostratigraphical resolution achievable using these fossils (amongst the earliest ammonites recorded in Britain) and to see the unique in-situ 'Nautilus Islands' palaeocommunity - the subject of current research. Later, if time permits we will examine the local building stones and  learn something about recent research into "new" Permo-Triassic Sandstone types.

Start time 10:15 am.

Meet at Car Park (free) at ST 0766 4333, at end of lane leading to Helwell Bay Holiday site (adjacent to Watchet Memorial Ground and Football Club). Depart beach by 14:30 hrs.

Watchet Town building stones 15:00-16:00 hrs. Finish 1600 hrs.

Note: There are NO toilet facilities at this meeting point. However, public toilets are available nearby in Watchet at both the Harbour Road (ST 0720 4331) and Market Street (ST 0704 4337) Car Parks. Both these Car Parks are Pay and Display. It is a 10-15 min stroll from these Car Parks to the Meeting Point (follow signs to 'Fossil Beach' and the public footpath along the coast north of the West Somerset Railway Line which leads straight to the Meeting Point).

Trip outline:

First part: North of the Doniford (Helwell) Bay Fault

An extensive area of intertidal 'reef' which superbly exposes a late Triassic to early Jurassic (Hettangian) sequence of interbedded limestones, mudstones and shales; these represent the oldest Jurassic sediments exposed on the West Somerset coast. The strata include highly fossiliferous 'Pre-planorbis Beds' and 'Aldergrove Beds' with extensive limestone platforms covered with fossil oysters ( Liostrea) and Psiloceras ammonites. This is a great opportunity to explore the evolution of and biostratigraphical resolution achievable using these fossils (amongst the earliest ammonites recorded in Britain).

Second part: South of the Doniford (Helwell) Bay Fault

Beach and cliff-side walk taking in the dark mudstones and shales assigned to the 'Doniford Shales' and 'Helwell Marls' of early Jurassic (early Sinemurian) age. These are the youngest Jurassic strata exposed on the West Somerset coast and are richly fossiliferous containing abundant bivalves (oysters including Gryphaea and pectinids) and ammonites (including the zonal index Arnioceras and some of the 'first giants' Coroniceras and Paracoroniceras). The strata also offer an opportunity to see the unique in-situ 'Nautilus Islands' palaeocommunity - the subject of current research.

If time permits, and people wish, we can then head back into Watchet (10 mins walk, for a cuppa, toilet break etc) and have a quick walk around the Esplanade, West Harbour area and Swain Street taking in some of the local building stones - including a brief introduction to one of the 'new' Permo-Triassic sandstone types currently being researched.

Volcanic Music

Eruptions Can Give Sound Warnings

THIS ARTICLE tells us that volcanic eruptions can give sound warnings. Villarrica volcano in Chile radiated very low frequency sound waves (infrasound) before erupting in March 2015.

Volcanoes can be compared to musical instruments. They are rather larger but the crater is rather like a horn. Its shape and size determines the sound produced. Lava rising in the crater lake changes the sound produced. 

One of the justifications volcanologists use for their research is that they can forecast eruptions. It seems that they will be adding microphones to their tool kit!

During the few days leading up to Villarrica’s 3 March 2015 explosion, the volcano’s characteristic explosion infrasound changed (top and bottom). Colored disks represent the spatial equivalents of the respective infrasound time series, which were recorded 4 kilometers from the vent; oscillations are mostly absent on 2 March. Waveforms on 27 February had well-defined oscillations that were mostly absent by 2 March (middle). Draped topography was created by the authors from the Shuttle Radar Topography Mission digital elevation model using an image from NASA Earth Observatory. VID and VIC are the stations that recorded the waveform data.

Two 4-Day Field Trips

Two 4-Day Field Trips in South West England

Nick Chidlaw is offering two field trips in the south west in the second half of September. He provides some background information followed by more particular details.

--------------------------------------------

Examination of the geology of south west England indicates that it was largely developed within a zone of plate tectonic collision. A key feature is the intensely folded and faulted nature of many of the rocks; these structures indicate that the rocks were compressed from a generally S to N direction in the geological past. This caused them to buckle up into rows of folds aligned approximately east-west, in many cases overturned to the north. Faulting of the rocks mostly took the form of high-angle ‘reverse’ and low-angle ‘thrust’ dislocations, along which extensive sheets (‘nappes’) of crust were carried over the top of others in a dominantly northerly direction. There is also evidence of major ‘strike-slip’ faults, where the crust either side of a near-vertical fault has moved in opposite directions relative to one another. One such fault locates north Devon some 400 km south east of its present position, in the Ardennes region, prior to such movement. It is now recognised that Devon and Cornwall are part of two discrete areas of crust that have highly contrasting geology to each other and that, although now juxtaposed, originated in different places and were created under different conditions. These are the ‘Cornubian Terrane’ (occupied by most of Devon and Cornwall), and the ‘North Armorican Composite Terrane’ (the northern margin of which occurs on shore in parts of south Devon and Cornwall). The rocks of the former terrane in the study area are mostly a variety of sedimentary rocks of Devonian age (419 – 359 Ma) which have been mildly metamorphosed; the latter terrane in the study area is mostly composed of rocks of a similar age, but which were originally ocean crust, and have been metamorphosed to a much greater degree. The highly deformed geology of south west England was created by plate tectonic collision, culminating at the end of the Carboniferous period in the ‘Variscan Orogeny’.  

 

Rocks formed subsequent to the Variscan Orogeny are widespread in south west England, and were created under crustal tension. In Permian times, mountainous land created by the plate collision, underwent extensive weathering and erosion, depositing coarse-grained sediments on slopes. De-compression of the orogenic belt allowed crustal melting at depth and the rising up into the higher crust of silica-rich magmas to form extensive granite intrusions together with smaller intrusions and volcanics, and causing alteration and metalliferous mineralisation of the adjacent rocks.    

------------------------------------

Please note that these field trips are independent of one another - you can decide to attend either or both, according to your interests and availability.

 

Some potential attendees may wish to attend both trips; there is a gap of 5 days between these trips, creating the opportunity for those people to stay in the south-west, and explore Devon and Cornwall ‘on holiday’ during this time.  

 

The two trips visit sites that are mostly coastal, and due regard to tidal conditions has been made, to enable maximum time available to study the rocks safely. 

 

Tuition fee is £85.00 per person per field trip.

 

If you / anyone else you know would like to attend either or both of these courses, please forward cheque payable to me to:

 

Dr N Chidlaw

8 Silver Street

Dursley,

Glos.

GL11 4ND

 

Bank transfer can be arranged if you do not use cheques - let me know.

 

Please provide me with your postal address - I will then be able to send you your trips handout(s) in good time before the trips run, should they become viable.

The deadline for the minimum number (10) of enrolments for both trips is Tuesday 13th August.  Maximum number of enrolments is 30. If the minimum of enrolments is reached by this deadline, the arrangements will continue; if not, the course will be cancelled and fees received will be returned to those who have sent them in, soon afterwards.

Please note that for each course you will need to:

Arrange your own transport and accommodation (such as B&B) if you live beyond commuting distance - tutor can advise

Bring your own packed lunch(es) each day, and any refreshments (e.g. flask of coffee, fruit juice, mineral water, high energy snacks etc.)

Wear strong footwear with good tread and ankle support, and warm waterproof clothing if weather is poor

Wear hard hats when below rock faces (bring one, or request from the tutor in advance of the trip(s) to borrow one)

You would be insured against accident for the duration of both trips.

Please see details of the two trips below. I hope this proposal is of interest to you, and to hear from you soon.

Regards,

NICK CHIDLAW.

GEOLOGY BETWEEN THE BOLT PROMONTORY AND DARTMOOR, SOUTH DEVON (Thursday 19th – Sunday 22nd September; 10.00 am – 5.00 pm each day)

 

This field trip focuses on the varied geology of the Bigbury Bay area, and at Plymouth and the nearby south west margin of Dartmoor. We examine rocks of both the North Armorican Composite Terrane and the Cornubian Terrane, and the boundary between; post-orogenic sediments are studied, as well as the south west margin of the Dartmoor granite and its effect on the adjacent ‘country’ rocks when it was intruded.

 

View of Outer and Inner Hope villages, Bigbury Bay west of Salcombe. Here, the North Armorican Composite Terrane (which continues south into France) and the Cornubian Terrane (occupied by most of Devon and Cornwall) meet. The boundary, (‘Start Boundary Fault’) lies on the left (north) side of the promontory extending out to sea on the left of this picture. The rocks south of the fault in this picture are heavily sheared, leading to the creation of the cove.  

----------------------------------

 

FIELD GEOLOGY ON THE LIZARD PENINSULA, CORNWALL  (Saturday 28th September – Tuesday 1st October; 10.00 am – 5.00 pm each day)

This field trip, located on the Lizard peninsula to the south of Falmouth, includes the southern margin of the Cornubian Terrane, and the northern margin of the North Armorican Composite Terrane. The nature of the boundary between the two will be examined. Deep water ‘turbidite’ sediments, highly deformed, and rocks formed by undersea landslides, both mildly metamorphosed, characterise the Cornubian Terrane rocks here. The North Armorican Composite Terrane rocks are composed mostly of the Lizard Complex, a much deformed and dismembered fragment of Devonian oceanic ‘lithosphere’ (crust and uppermost mantle).  Such remnants of oceanic rocks, that became driven up onto continents through plate tectonic activity, are known as ‘ophiolites’.   

View of Kynance Cove on the south west side of the Lizard Peninsula. Here, peridotite rock from the Devonian earth’s upper mantle has been extensively altered to variably-coloured serpentine. The least-altered peridotite on the Lizard is black on colour (due to finely-disseminated magnetite). Much of the alteration may have occurred in Devonian times, when the ocean crust was under tectonic tension, allowing sea water to penetrate down into these upper mantle rocks, causing the ‘serpentinisation’.

18th June Sandhurst and Wainlode 

The River Severn has eroded its course maily along the outcrop of the soft Triassic Mercia Mudstone or the Jurassic Lower Lias Clay. In between these formations is a thin series of beds of more resistant rock – the Rhaetic, which forms a series of low wooded ridges broken by faults, and occasionally cut into by the river (as at Aust, Sedbury, Westbury and here at Wainlode) to form impressive cliffs. This location is also a classic area to observe the Severn Terraces. Meet initially at the car park (along the lane) of the pub The Red Lion, at the foot of Wainlode Hill (SO848259), from where we will travel in a few cars to Sandhurst for a linear walk of about 3km with a climb of about 60m.

Parallel Roads of Glen Roy

Parallel Roads of Glen Roy

A source has sent me a video, taken from a drone, of the Glen Roy area. You can download it from HERE. Unfortunately it will not play on the blog.

It would benefit from editing and some commentary, either spoken or in the form of captions, but it does indicate the possibilities of using drones in geologic education. Also filming, while heading into the sun, should be avoided!

But it does give me the opportunity to recommend a book which I recently bought:- Land of Mountain and Flood, The Geology and Landforms of Scotland by Alan McKirdy, John Gordon and Roger Crofts. ISBN: 978 1 78027 497 3. Published by Birlinn Limited.

Their explanation of the Parallel Roads is given below. You can download the PDF for this page HERE. (The watermark is there because I am evaluating an alternative to Adobe Acrobat - which now costs too much).

The book looks like it should be on a coffee table - big, lots of pictures, glossy - but it is written by people who know their stuff and it shows. Many of the people they acknowledge as having inspired them, taught me when I was at Aberdeen University, so it must be good!
