September 2018
Understanding Geology and Scenery around Ross-on-Wye
Starts September 21st (not 25th
Oct or 8th Nov), finishes 6th December.
This
10 week course aims to introduce you to the ways in which the varied and
beautiful landscape round our area has come into being. The effects of folds,
faults and tectonic dip in exposing
different rock types, and the past and present processes of uplift,
weathering, erosion and deposition that have acted upon them, will be examined
by reference to local scenery. Use will be made of local maps and
cross-sections across them, both geological and topographic; together with
specimens of local rocks. Contact Paul Mason on
01989 760399. Cost £60 Enrol before 15th September to ensure that the
course runs.
Geology of the Bristol and Gloucester Region.
One of the most varied regions of Britain, spanning the
major divisions of the Variscan Front/Bristol Channel-Bray Fault, and the
Malvern fault/ Worcester Graben, incorporating rocks varying in age from late
PreCambrian to Cretaceous, and three of the terranes making up the geological
“jigsaw” of Britain. The course will cover roughly the area covered by the
eponymous BGS publication in the British Regional Geology series (3rd
edition 1992). Starts Mon 17th
September for 10 weeks (not 22nd
or29th Oct or 5th Nov), until 10th December Held at Wynstones School, Stroud Road,
Whaddon, Gloucester from 7.30-9.30pm on Mondays. Cost £75 (including tea, coffee etc at
breaktime!).
October 2018
Field Course: The Geology of Northern Cyprus and NW Turkey.
Dates will be
for a week to 10 days trip around a period from 19th to 31st October (half term in Glos). Half the time
will be spent in N Cyprus and half in Turkey, in the area around and to the
south west of Istanbul. A wide variety of geology is exposed; from the Kyrenia Terrane of N Cyprus, spectacularly exposed in the
narrow, and still rising, mountain range that forms the entire northernmost
coast, but deeply buried beneath the younger sediments of the Mesoria Basin to
the south. Jurassic and Cretaceous sediments were folded and metamorphosed
during subduction in the late Cretaceous, then exhumed, eroded and covered by
latest Cretaceous-Palaeogene sediments and volcanics, then by an Eocene
melange; the whole being thrust and folded by Eocene collision with Troodos. Turkey
was
not a single entity until the Early Tertiary, when several continental fragments
with independent Palaeozoic and Mesozoic geological histories were assembled
during a complex sequence of events leading to the collision of Gondwana and
Laurasia. We shall examine the Istanbul and Sakarya terranes, which were
detached parts of Laurasia, undergoing Triassic subduction, collision and
obduction/exhumation of ophiolites, including some of the best high pressure
metamorphic rocks in the world.
November - December 2018
Field
Course: 30th Nov – 2nd Dec (and possibly
Monday 3rd too) Geology of the
Quantocks and West Somerset
A
classic area for the study of the folded Upper Palaeozoic basement in the
Quantocks and Cannington Park, and the unconformable Triassic and Jurassic
sequence exposed in faulted basins associated with the Bristol Channel fault.
What is the evidence for and against massive Variscan movement of formerly
widely separated terranes along this fault? Excellent exposures, particularly
of the Mesozoic rocks at and near the coast.
17th
December (Monday) Annual Geological Reunion Dinner at Watersmeet, Hartpury 7.30 for 8.00pm
January 2019
The
Geology of Eruptions, Earthquakes and Tsunamis
Three of the most devastating natural
disaster-forming events are geological, all related to plate tectonics, and are
very difficult, if not impossible, to accurately forecast. What are the causes of these events and their
various manifestations? Why are some more dangerous than others? How can we
prevent or mitigate these effects? Examples of some of these phenomena will be
used to illustrate these points Monday 7th for 10 weeks (not 18h
Feb) until 18th March. Held at Wynstones School, Stroud Road,
Whaddon, Gloucester from 7.30-9.30pm on Mondays . Cost £75
Advances in Understanding Earth’s Structure and Operation.
This 10 week
course aims to introduce you to relatively new ideas, some accepted, some
controversial, about the internal structure and tectonics of the Earth. Many
ideas have changed radically since the inception of the Plate Tectonic hypothesis,
and especially in the period from the 1990s, partly as a result of new
technology, and the re-examination of parts of the theory that evidence did not
support. Each week we will examine a different topic, such as subduction,
mantle dynamics, mantle plumes. Held at The Chantry, Thornbury. First meeting 7.30 – 9.30, Thurs 10th January
until March 21st (not Thurs 21st Feb). Cost £75
February 2019
Possible Field Course: The Geology of Neapolitan Volcanoes and their Eruptions
Dates will be for
a week trip around a period from Fri 15th
to Monday 25th . LET ME KNOW
BEFORE CHRISTMAS IF YOU WANT TO COME to take advantage of cheaper air fares and
determine the viability of such a trip.
April 2019
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.
June - July 2019
Field Course: Tues 4th June - Tues 16th July Geology and Landscape in Gloucestershire
(evening field course Tuesdays 7-9 First
meeting point:- Stinchcombe Hill: Meet

(beyond the golf course car park) .
Further sessions on website,
separate leaflet, and/or by contacting Dave Green.
