MONDAY 24TH
Course - The Practical Study of Minerals
When
Mon, 24 June, 19:30 – 21:30
Where
Wynstones School, Stroud Rd, Whaddon, Gloucester (map)
Description
The Practical Study of Minerals .
How to identify minerals using techniques based on both physical (crystallographic, twinning, cleavage, hardness, density, streak, colour, lustre, acid reaction, taste etc) and optical properties under the petrological microscope (relief, pleochroism, birefringence, extinction etc) Monday 29th April, for 10 weeks, until 15th July (not 6th nor 27th May). Held at Wynstones School, Stroud Rd, Whaddon, Gloucester from 7.30-9.30pm on Mondays. Cost £75.

Tuesday 25th
Dave Green - Geology and Landscape
When
Tue, 25 June, 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

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

Where
Doniford (Helwell) Bay, Watchet, West Somerset (map)
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.
